April 22, 2026, Pentwyn Reservoir

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.

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.
