Welcome

Planted by the Forestry Commission in the 1930s, Hafren Forest is named after Afon Hafren (the Welsh name for the River Severn).

The source of the River Severn is in a peat bog on the slopes of Pumlumon, Mid Wales’ highest mountain. In no time at all it becomes a torrent with falls and cascades plunging headlong through the forest.

A walk along one of the trails, which are waymarked from the car park, is a great way to enjoy this beautiful river.

The longest route takes you to the source of the Severn, just outside the forest’s boundary.

The shorter trails go to waterfalls within the forest, including the famous Severn-Break-its-Neck.

Hafren Forest is also home to many public footpaths and bridleways and it is the starting point for two long distance walks.

There are pleasant picnic areas near the car park and a riverside accessible trail to a viewing platform over the cascades.

Walking trails

The walking trails are waymarked from start to finish.

Look out for the information panel at the start of the trails in the main car park (Rhyd-y-benwch).

Find out about walking trail grades.

Cascades Walk

Grade: Accessible
Distance: ½ mile/0.9 kilometres
Time: 30 minutes
Trail information: The trail follows a sloping path from the car park to the boardwalk. It returns on a well surfaced wide path through the forest.

The Cascades Walk goes down to a boardwalk along the riverbank and along the side of the tumbling cascades.

Here there is a raised platform to enjoy the view before returning through the forest to the car park.

Severn-Break-its-Neck Trail

Grade: Moderate
Distance: 1¾ miles/2.8 kilometres
Time: 1 hour
Trail information: The trail follows a level path along the river, before going up some steps to a boardwalk through the meadow and then onto a stoned path to the waterfall. There are steep narrow steps down to the bridge over the waterfall, and a short but steep climb back onto the forest road which the trail follows back to the car park.

The Severn-Break-its-Neck Trail sets off alongside the river and then goes through a wildflower meadow with a boardwalk section.

It crosses a footbridge where the River Severn thunders down a gully and forms the famous Severn-Break-its-Neck waterfall.

It returns to the car park on a forest road with views across the forest.

Blaen Hafren Falls Trail

Grade: Moderate
Distance: 3¾ miles/6 kilometres
Time: 1½ hours
Trail description: The trail follows a well-surfaced path with compact gravel and loose stones to the waterfall. It returns on a forest road. There are some steep ascents and descents and several benches along the route.

This scenic route goes through the heart of the forest alongside the River Severn to Blaen Hafren Falls.

Source of the Severn Trail

Grade: Strenuous
Distance: 8 miles/13 kilometres
Time: 4½ hours
Trail information: The trail sets out on a well-surfaced path with compact gravel and loose stones. The there-and-back section to the source of the Severn is on stone slabs and a path of loose stone; there may be sheep on this section. The return route is via forest road and a narrow loose shale riverside path. Some steep ascents and descents and several benches along the route.

The Source of the Severn Trail leads alongside the river and through the forest to Blaen Hafren Falls.

It then climbs steeply to the forest boundary and onto a stone path through boggy moorland to the Severn’s source on Pumlumon - the source is marked by a carved wooden post.

The trail passes by some heritage features including a standing stone and the remains of a mine and a farmstead - look out for the information panels along the route.

Ospreys in Hafren Forest

Ospreys spend the summer by a reservoir in Hafren Forest called Llyn Clywedog.

These large birds of prey return to Africa in late August.

You can watch the live feed from one of the osprey nests during the breeding season (normally March to August).

Two live stream cameras film the nest 24 hours a day.

Live footage from both cameras is available on YouTube by searching “Llyn Clywedog Ospreys”, or by using the following links:
