Pentwyn Reservoir is the smaller sister to Pontsticill Reservoir, both being separated by a causeway going towards the old Dolygaer outdoor centre. It is a very popular spot with fishermen and outdoor enthusiasts alike. The reservoir is used daily for a mix of watersports such as paddle boarding, kayaking, canoeing and raft building. It is in a beautiful setting, and you have great views north towards Pen y Fan and nice walks nearby.

This is great fun, I've done both descents now, both north and south but neither climb, and I'm very happy about that. Would want an unloaded bike to clean the whole trail.

An impressive sight and a wonderful tribute to the miners that lost their lives

To access this area is a very steep incline and decline into this valley section 7- 9% gradient in either direction. The Taf Fechan LNR comprises about 2.5 km of river with steep valley sides of Carboniferous limestone. The river has eroded the limestone into a narrow gorge in the centre of the site. A mosaic of deciduous woodland on the slopes with a canopy of Beech, Birch and Ash, gives way to Alder and Grey Willow closer to the river.
