Hedgehogs are welcome visitors in many UK gardens. They feed on a range of insects and invertebrates, move quietly through borders at night and are a familiar part of British garden wildlife. If you have seen one near your fence line, you may have wondered whether hedgehogs can climb wooden fences, or whether they need a gap to pass through instead.
The simple answer is that hedgehogs can sometimes climb rough or low obstacles, but they are not natural climbers. They are ground-dwelling animals with short legs, round bodies and a strong preference for moving along the ground. A wooden fence may be possible for a determined hedgehog to climb in certain conditions, but it is not a safe or reliable route.
If you want to make your garden hedgehog-friendly, the best approach is not to expect hedgehogs to climb over fences. It is much safer to provide ground-level access through hedgehog holes, small gaps beneath boundaries or gravel boards with hedgehog holes built in.
Can hedgehogs climb wooden fences?
Hedgehogs can climb some rough surfaces, including low timber, stones, mesh, stacked materials and uneven garden features. Their claws can grip textured surfaces, and they are stronger and more determined than their shape suggests.
However, climbing is not what hedgehogs are built for. A tall, smooth or vertical fence is difficult for them, and even if they manage to climb up, getting down safely is another problem. A fall from height can injure a hedgehog, especially if it lands on paving, gravel, tools, pots or other hard objects.
So, while a hedgehog may be able to climb a wooden fence in the right circumstances, it should not be relied on as a normal route through a garden.
Why hedgehogs are mainly ground-dwelling animals
Hedgehogs spend most of their time at ground level. They search through grass, leaf litter, borders, hedges and compost areas for food. Their bodies are designed for walking, foraging, curling up for protection and pushing through low vegetation.
They do not climb in the same way as squirrels, cats or rats. Their legs are short, their bodies are rounded and they do not have the same balance or agility as true climbing animals.
This means garden design should help hedgehogs move at ground level rather than forcing them over fences, walls or steep barriers.
Why hedgehogs need to move between gardens
A single garden is usually too small to provide everything a hedgehog needs. Hedgehogs can travel surprisingly far at night in search of food, mates, nesting sites and shelter. Garden boundaries can interrupt these natural routes.
They may need to move between gardens to find:
- Beetles, worms and other invertebrates
- Safe nesting areas
- Dry shelter
- Access to water
- Routes away from danger
- Mates during the breeding season
- Suitable hibernation sites
Solid fences, walls, concrete gravel boards and sealed garden gates can make it harder for hedgehogs to move safely. When gardens are linked together, hedgehogs can travel without needing to cross as many roads or exposed areas.
Why climbing fences can be risky for hedgehogs
Even if a hedgehog can climb a rough wooden fence, it may not be safe. The climb itself can be difficult, and the landing area may be hazardous.
Risks include:
- Falling from height
- Landing on paving or sharp objects
- Getting trapped behind stored items
- Becoming caught in netting or wire
- Falling into ponds or drains
- Becoming stuck between fences and sheds
- Being unable to return the same way
A hedgehog that climbs into a garden may not easily climb back out. This can leave it trapped, especially if the fence line has no ground-level exit.
Ground-level access is better than climbing
The safest way to help hedgehogs is to provide a ground-level route. This is often called a hedgehog highway. It allows hedgehogs to move between gardens without climbing.
A hedgehog access hole does not need to be large. A small opening at the base of a fence or wall can be enough for a hedgehog to pass through while still keeping most domestic pets contained.
Ground-level access is usually better because it is:
- Safer than climbing
- More natural for hedgehogs
- Easier for young or weaker hedgehogs
- Less likely to cause falls
- Simple to include in new fencing
- Often easy to retrofit into existing boundaries
If you are installing new fence panels, gravel boards or garden gates, it is worth planning hedgehog access from the start.
What size should a hedgehog hole be?
A commonly recommended hedgehog hole size is around 13cm by 13cm. This gives enough space for a hedgehog to pass through while keeping the opening relatively small.
The hole should be at ground level and should not have sharp edges. It should open into a safe area on both sides of the fence.
If you are creating a hole in a fence panel, gravel board or timber boundary, check that the structure remains strong and stable afterwards. Do not cut into posts or important structural sections.
Using gravel boards with hedgehog holes
Gravel boards are often used at the base of fence panels to protect the timber from damp ground. They are useful for extending the life of fence panels, but a solid gravel board can block hedgehog movement if there are no gaps elsewhere.
A gravel board with a hedgehog hole can solve this problem. It gives the fence a tidy, protected base while still allowing hedgehogs to pass through safely.
This is particularly useful where:
- New fence panels are being installed
- Concrete gravel boards are being used
- The fence line is otherwise fully sealed
- You want a neat, permanent hedgehog access point
- You are replacing an old boundary with a more wildlife-friendly option
When fitting a hedgehog-friendly gravel board, make sure the opening is not blocked by soil, stones, paving, edging or dense planting.
Can hedgehogs get under fence panels?
Hedgehogs can pass under fence panels if there is a suitable gap. However, many modern fences are installed with gravel boards or panels close to the ground, which can prevent access.
A small, safe gap can be helpful for hedgehogs, but it must be considered alongside other needs. If you have small dogs, rabbits, guinea pigs or other pets, you may need to manage access carefully.
Where a simple gap is not suitable, a dedicated hedgehog hole in a gravel board or low section of fencing can give a more controlled route.
Can hedgehogs climb trellis?
Hedgehogs may be able to scramble up low, rough or angled trellis, but trellis should not be used as a main access route. It is designed for climbing plants, not for hedgehogs.
There is also a risk of hedgehogs becoming trapped or falling if they try to climb unstable, loose or narrow trellis. Ground-level access is safer.
Trellis panels are still useful in a wildlife-friendly garden because they support climbing plants, provide cover and create habitat for insects. They should simply be paired with safe ground-level access through the boundary.
Can hedgehogs climb walls?
Hedgehogs may climb low stone edges, rough banks or uneven structures, but high walls are a major barrier. Smooth walls are particularly difficult.
If a garden is enclosed by walls, a hedgehog hole may need to be created at the base where safe and practical. Alternatively, access may be possible through a gate gap or a purpose-made passage.
Before making any changes to a wall, consider its structure, ownership and any restrictions. Do not weaken a boundary wall by cutting into it without proper advice.
Can hedgehogs climb steps?
Hedgehogs can manage some shallow steps, especially if the rise is low and the surface gives grip. Steep steps, smooth steps or open gaps can be difficult and risky.
If you want to help hedgehogs move through a garden with level changes, a shallow ramp, planted slope or low stepped route may be safer than a steep drop.
Make sure any ramp or route does not lead to hazards such as ponds, drains, roads or steps they cannot return up.
Should you add a ramp for hedgehogs?
A shallow ramp can help in specific situations, such as helping hedgehogs leave a pond edge, move out of a sunken area or cross a small level change.
However, a ramp over a fence is not usually the best solution. It may be too steep, unsafe, unstable or attractive to other animals. It may also allow hedgehogs to climb into a space they cannot leave.
Where possible, create a safe hole at ground level rather than a climbing route over the fence.
How to make a fence hedgehog-friendly
A hedgehog-friendly fence provides safe access at ground level while still working as a boundary for the garden.
Ways to improve a fence include:
- Adding a hedgehog hole at the base
- Using a gravel board with a hedgehog opening
- Leaving a safe gap beneath part of the fence
- Checking that the opening is clear on both sides
- Avoiding sharp mesh or jagged timber around the hole
- Keeping the route away from ponds, drains and steps
- Making sure pets cannot escape if this is a concern
- Speaking to neighbours about linked access routes
The best route is simple, low, clear and safe.
Where to place a hedgehog hole
The position of the hedgehog hole matters. It should allow safe travel between gardens without leading directly into danger.
Good places include:
- Quiet corners of the garden
- Near hedges or planted borders
- Away from busy patios
- Away from ponds without escape ramps
- Away from open drains or holes
- Where neighbours are happy to allow access
- Where the opening can remain clear
A hedgehog hole hidden by light planting can feel safer for hedgehogs, but do not let it become blocked by soil, leaves or dense growth.
Check both sides of the fence
Before creating a hedgehog hole, check what is on the other side. A safe opening on your side is not enough if it leads to a drop, a pond, a dog run, a road or an area where the hedgehog could become trapped.
If the boundary is shared with a neighbour, discuss the idea first. Hedgehog highways work best when several gardens are linked together.
Do not cut holes in a neighbour’s fence, wall or gravel board without permission.
Hedgehogs and garden gates
Garden gates can either help or block hedgehog movement. A small gap beneath a gate may allow hedgehogs to pass through, but it may also allow pets to escape or unwanted animals to enter.
If the gate gap is suitable and safe, it can form part of the hedgehog route. If you need a secure gate for pets, consider adding a dedicated hedgehog hole elsewhere in the fence line.
Check that gate hardware, thresholds and edging do not create sharp or trapping points.
Hedgehogs and closeboard fencing
Closeboard fencing provides strong privacy and security, but it can create a solid barrier for hedgehogs if it is installed tight to the ground or with continuous gravel boards.
If you are using closeboard fence panels or traditional closeboard fencing, include a hedgehog access point where appropriate. This might be a small opening in a gravel board, a purpose-made gap at the base or a route through a less visible section of boundary.
Make sure the access point does not weaken the fence or leave an unsafe edge.
Hedgehogs and slatted fencing
Slatted fence panels may allow airflow and partial visibility, but the gaps between slats are not normally intended for hedgehog access. Hedgehogs need a safe opening at ground level, not narrow gaps higher up.
If using slatted fence panels, still include a ground-level route if you want the garden to be hedgehog-friendly.
Hedgehogs and picket fencing
Picket fence panels are often more open than solid panels, and hedgehogs may be able to pass through or under them depending on the design. However, the gaps must be safe and not too narrow.
If the picket fence sits above the ground, it may already allow movement. If there is a base rail or gravel board, a dedicated opening may still be needed.
Hedgehogs and mesh fencing
Mesh fencing can be risky if the holes are large enough for a hedgehog to partly enter but too small to pass through cleanly. Hedgehogs can become stuck in unsuitable netting or mesh.
If using mesh near hedgehog routes, choose a safe design and check it regularly. Avoid loose garden netting at ground level, especially around vegetable patches, ponds and fruit cages.
Loose netting is one of the common hazards for hedgehogs in gardens.
Other garden hazards for hedgehogs
Hedgehog access is only useful if the garden itself is safe. Once hedgehogs can enter, check for hazards.
Common risks include:
- Open drains
- Ponds without escape ramps
- Loose netting
- Deep holes
- Sharp garden waste
- Uncovered post holes during fence installation
- Bonfire piles
- Pesticides and slug pellets
- Strimmers used without checking long grass first
- Dogs left unsupervised with hedgehogs
A hedgehog-friendly garden should provide access, cover, water and safe routes.
Hedgehogs and ponds
Hedgehogs can swim, but they can drown if they cannot get out of a pond. If you have a pond, provide a shallow edge, stones, a ramp or planting that allows wildlife to escape.
This is especially important if you create hedgehog access into the garden. A hedgehog hole near a pond should only be used if the pond has safe exit points.
Hedgehogs and garden netting
Garden netting can trap hedgehogs. This includes loose fruit netting, football goal netting, pea netting and mesh left at ground level.
Keep netting raised off the ground where possible and store unused netting safely. Check netted areas regularly, especially if hedgehogs are known to visit.
If you are using netting to protect crops, make sure it is taut, secure and not lying loose along the soil.
Hedgehogs and bonfires
Hedgehogs may nest in piles of leaves, branches and garden waste. Bonfires are dangerous if they are lit without checking first.
If you build a bonfire, move the material to a fresh spot before lighting wherever possible. Check carefully for hedgehogs and other wildlife.
Never assume a pile of garden waste is empty.
Hedgehogs and lawn care
Hedgehogs may forage in lawns, especially where there are beetles, worms and other invertebrates. Lawn care can affect how useful the garden is to them.
To make lawn areas safer:
- Check long grass before mowing or strimming
- Avoid unnecessary chemical use
- Keep some planted edges for cover
- Provide shallow water in dry weather
- Leave some leaf litter in quiet areas where suitable
A perfectly tidy garden is not always the most useful for wildlife. A balanced approach works better: keep main areas neat and allow quieter corners to be more natural.
Should you feed hedgehogs?
If hedgehogs visit regularly, you can provide supplementary food, especially during dry periods or when natural food is limited. Suitable hedgehog food or meaty cat or dog food is often used. Fresh water is important.
Avoid bread and milk. These are not suitable for hedgehogs and can cause problems.
If feeding, keep the area clean and avoid attracting rats. A feeding station can help limit access by cats and larger animals.
Hedgehog houses and shelter
A hedgehog house can provide shelter, but it should be placed in a quiet, sheltered part of the garden. It should not be in a busy path, exposed patio or area likely to flood.
Natural shelter is also useful. Leaf piles, log piles, dense shrubs and quiet corners can all help.
If you are installing new fencing, sheds, decking or landscaping, check for hedgehogs before clearing old piles of material or dense growth.
Making a garden more hedgehog-friendly
A hedgehog-friendly garden does not need to be wild everywhere. It simply needs safe movement, shelter, food sources and reduced hazards.
Useful features include:
- Hedgehog holes through fences or gravel boards
- Quiet planted borders
- Log piles
- Leaf litter in selected areas
- Wildlife-friendly ponds with escape routes
- Fresh water
- Reduced pesticide use
- Safe compost areas
- Gaps under hedges where suitable
- Trellis and planting that support insects
Linking gardens together is one of the most helpful actions. A single hedgehog hole is useful, but a connected row of gardens is better.
Retrofitting hedgehog access into an existing fence
If your fence is already installed, you may still be able to create access. The method depends on the fence type.
Possible options include:
- Cutting a small opening in a timber gravel board
- Adding a neat framed hole at the base of a fence panel
- Creating a small gap beneath a gate where safe
- Replacing one gravel board with a hedgehog-friendly version
- Adding a short tunnel through a planted boundary
Do not cut into structural posts or weaken the fence. Smooth any rough edges and check the opening regularly.
Adding hedgehog access when installing new fencing
The best time to plan hedgehog access is when installing new fencing. It is easier to include a suitable opening before the fence is finished.
If you are ordering fence panels, fence posts and gravel boards, decide where the hedgehog route will go before installation starts. Make sure it does not conflict with gates, posts or areas where pets need to be contained.
Hedgehog-friendly gravel boards are a neat option because they provide a built-in opening without leaving the fence line looking unfinished.
Common mistakes when helping hedgehogs
Good intentions can sometimes create problems. Avoid making changes that let hedgehogs into unsafe spaces or trap them.
Common mistakes include:
- Expecting hedgehogs to climb over fences
- Creating a hole that leads to a drop or hazard
- Leaving sharp edges around an opening
- Blocking the hole later with soil or pots
- Using loose netting at ground level
- Forgetting to check both sides of the boundary
- Adding a ramp that is too steep or unstable
- Using slug pellets or pesticides without considering wildlife
- Lighting bonfires without checking for hedgehogs
- Cutting a hole in a shared fence without permission
The goal is safe access, not just any access.

Frequently asked questions
Can hedgehogs climb wooden fences?
Hedgehogs can sometimes climb rough or low wooden obstacles, but they are not natural climbers. A tall or smooth wooden fence is a significant barrier, and climbing can be risky. Ground-level access is much safer.
Can hedgehogs climb trellis?
They may be able to scramble up low or rough trellis, but trellis should not be used as their main route. It can be unstable or unsafe. A hedgehog hole at ground level is better.
How do hedgehogs get through fences?
Hedgehogs usually move through gaps at ground level, under gates, beneath hedges or through purpose-made hedgehog holes in fences or gravel boards.
What size hole does a hedgehog need in a fence?
A commonly recommended size is around 13cm by 13cm. This is usually large enough for a hedgehog to pass through while remaining small enough for many domestic garden boundaries.
Can hedgehogs get under gravel boards?
Only if there is a gap. Solid gravel boards can block hedgehog movement. A gravel board with a hedgehog hole gives access while still protecting fence panels.
Should I make a hedgehog hole in my fence?
If it is safe and you have permission where needed, a hedgehog hole can be very helpful. Check what is on both sides of the fence and make sure the opening does not create risks for pets or wildlife.
Can hedgehogs climb walls?
They may manage low, rough or uneven walls, but high or smooth walls are difficult barriers. A ground-level route is safer where possible.
Are hedgehogs good for gardens?
Hedgehogs are generally welcome garden visitors. They feed on a variety of invertebrates and form part of a healthy garden ecosystem.
What hazards should I remove for hedgehogs?
Check for loose netting, ponds without escape routes, open drains, deep holes, bonfire piles, sharp waste and unsafe gaps around sheds or fences.
How can I make my garden more hedgehog-friendly?
Create safe access between gardens, provide water, reduce chemical use, leave some cover, check for hazards and consider adding a hedgehog house or quiet natural area.
Final thoughts
Hedgehogs are more capable than they look, and they may sometimes climb rough wooden fences or low obstacles. However, climbing is not natural or safe for them. A fence that forces hedgehogs to climb can trap them, injure them or prevent them moving through the area altogether.
The best way to help hedgehogs is to provide safe ground-level access. A small hedgehog hole in a fence, a carefully planned gap beneath a boundary or a gravel board with a hedgehog hole can make a real difference.
When planning fence panels, gravel boards, trellis panels or garden gates, think about wildlife as well as privacy and security. With a few simple changes, a garden can remain practical for people while still allowing hedgehogs to move safely through the landscape at night.
