Talybont Reservoir is a great asset to the local scenery and is easy on the eye. It is surrounded by hiking and biking trails, but it is disappointing that this big water source can't be used for water recreation purposes.

A fantastic long, slightly downhill gravel stretch high above Talybont Reservoir, this trail delivers both in terms of adrenaline and views! The track is wide and mostly quiet, though the gravel can be loose and a bit chunky in sections, so a gravel bike, sturdy tourer or mountain bike is best.

Llangasty (St Gastyn's Church). A lovely place to stop on the southern shore of the largest natural lake in south Wales.
