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.

A remnant of Merthyr's past. This bridge carried a railway line that either took you through a tunnel to Aberdare or sent you north towards Cefn Coed and on to Brecon via Torpantau. Under the bridge was the Merthyr to Cardiff Glamorganshire canal which carried the produce of Cyfarthfa iron works to the ports of Cardiff which was then shipped all over the world.

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.
