The car park stands on the site of a farmhouse which once bore the name Rhyd y Benwch (Upper Ford). Now the Rhyd-y-benwch picnic site acts as a gateway to a number of waymarked forest walks.
Natural Resources Wales have created a number of different trails along the Severn and through the towering pine and spruce trees. All four routes are circular and are focused around the picnic area and toilet facilities at Rhyd-y-benwch.
In addition, the numerous forestry tracks and roads are also excellent terrain for the cyclist. The picnic site is situated next to a wildflower meadow which is at its best in late July.
The Source of the Severn Trail and one of the peaks of Pumlumon (Pen Pumlumon Arwystli 741m, 2431ft) can be reached from the car park along waymarked walks.
Trails can become slippery due to adverse weather conditions. Please take extra care when in the forest. Suitable footwear should be worn at all times.
In Llanidloes town centre, face the Market Hall from Great Oak Street and take Short Bridge Street directly opposite. Follow the narrow road to Old Hall and then on to the Rhyd-y-benwch car park.
The Rhyd-y-benwch car park can also be reached from the northern end of Llyn Clywedog on minor roads.
The nearest train station is Caersws.
