5. Henllys Vale
This walk alongside the Afon Twrch (Twrch means boar in Welsh) leads to the former lime kilns and chimney of Henllys Vale. The route follows the old rail/tram route from the colliery site.
The footpath has recently been improved to allow easier access however halfway along the route is a short and moderately steep natural incline. The Afon Twrch is home to a range of wildlife including birds such as the (white-breasted) Dipper.
The route up to and over the footbridge is level and surfaced. Beyond the footbridge the path is compacted earth and short grass. The river bank closer to the lime kilns is eroding in places so care should be taken. When you get closer to the lime kilns, there are short slopes, some natural and stone steps and the path becomes narrow in places.
How to get there: Henllys Vale is just off the A4068 at Ystradowen between Ystradgynlais and Brynaman. The start of the walk can be reached by turning off by the bus stop on the corner of the main road (A4068) in Ystradowen. Follow this road past the park and down a hill to the stone bridge. Cross the bridge and park in the natural pull-in by the large boulders. The walk starts at the kissing gate.
