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

Named after the rabbit warren which once provided a source of food, this area has seen huge changes since Radnor Forest was an ancient hunting forest.

In those days, it was a large moorland but in Victorian times the then-owners, the Harpton Court Estate, decided to create a “picturesque” forest and planted lots of trees.

You can see many of these trees, which are now huge, on our three waymarked walking trails which follow historic walking routes.

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

Radnor Forest

View from Fishpools Trail, Radnor ForestWarren Wood is in the area known as Radnor Forest.

Radnor Forest was once a royal hunting ground but it wasn’t an area covered in trees, which is our understanding of the word ‘forest’.

To the Norman kings it was an unenclosed piece of land, legally set aside for them 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.

Walking trails

Waterfall Walk

⅓ mile/0.5 kilometres (one way), easy

This mainly level 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

¾ mile/1 kilometre, moderate

This circular woodland walk leads you to a viewpoint above the famous Water-Break-its-Neck waterfall. The trail then goes up and over an old stone arched footbridge with views down into the waterfall gorge.

Warren Trail

1½ miles/2.3 kilometres, strenuous

The Warren Trail is an energetic ramble with a climb of 560 feet (170 metres).

This circular 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!
