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.

definitely fine to walk through here but maybe not in the week on a bike. It was pretty much deserted on a Sunday so we were able to avoid the busyish B road albeit at a much slower pace. Best east to west.

the lower reservoir has a nice flat road next to it, a welcome relief after the lumpy roads that lead to it from either direction.
