Warren Wood, near New Radnor

What's here

The car park and trails at Warren Wood will be closed from the end of July to allow for trees infected with Ash Dieback to be felled safely. During the closure, we will also upgrade parts of the boardwalk. Find another place to visit on the Days Out webpage.


Currently no access to the Water-Break-its-Neck waterfall.


We have closed the boardwalk that leads to the waterfall on the Waterfall Walk. Ash Dieback has infected many of the trees on either side of the boardwalk. This may have weakened the trees and could cause them to fall onto the boardwalk.


Warren Wood has been popular with tourists for over 200 years because of the waterfall known as Water-Break-its-Neck.

This is a spectacular sight after rain but can become a trickle after a long dry spell.

Warren Wood is named after the rabbit warren which once provided a source of food and this part of Radnor Forest has seen huge changes over the centuries.

The Victorian landowners created a forest in the popular Picturesque style by planting trees on the moorland.

You can see many of these trees, which are now huge, on our walking trails.

There is a small picnic site in the parking area which you pass on your way to the main Warren Wood car park.

Walking trails

Waterfall Walk

Currently no access to the Water-Break-its-Neck waterfall.

  • Grade: Easy
  • Distance: ½ mile/0.9 kilometre (there and back)

This short walk goes along a steep-sided gorge to the waterfall, which was a popular destination for Victorian tourists.

The waterfall is a spectacular sight after a few days of rain but it can be reduced to a trickle after a long hot spell.

The trail returns via the same route to the car park or you can join one of the longer trails through the wood.

Water-Break-its-Neck Trail

  • Grade: Moderate
  • Distance: ½ mile/1 kilometre (there and back)

This woodland walk goes above the famous Water-Break-its-Neck waterfall and has views down into the gorge.

Warren Trail

  • Grade: Strenuous
  • Distance: 1½ miles/2.3 kilometres

This is an energetic ramble with some steep climbs.

This route has great views of some of the largest trees in Radnorshire, many of which were planted in Victorian times.

Look out for the monkey puzzle trees!

Radnor Forest

Warren Wood is in the area known as Radnor Forest.

Radnor Forest was once a royal hunting ground. In those days it wasn’t an area covered in trees but an unenclosed piece of land, legally set aside for the Norman kings to hunt deer.

Today Radnor Forest is a land of hill farming and great moorlands, steep narrow valleys and hills, rising up to the highest point in Radnorshire, Black Mixen at 2150 feet (650 metres).

There are walking trails at two other woodlands managed by Natural Resources Wales within Radnor Forest.

Go to Nash Wood and Fishpools for more information.

Closures and diversions

Sometimes we need to close or divert trails for your safety whilst we undertake maintenance work or other operations.

We may have to close a site in extreme weather, such as high winds or snow and ice, due to the risk of injury to visitors or staff.

Please always follow any instructions on site and any temporary diversion signs.
