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.

I have been coming up here now for about forty years. There are a variety of routes to here, but each one brings you to this one spot. These lumps of stone and the views are drop-dead gorgeous. Top it off with a visit to the pub afterwards, and it's a good day out. It's also a good run—before you get to the pub, of course!

The Pontsticill Reservoir is filled by the Taf Fechan via the Pentwyn Reservoir directly upstream. It was built by damming the valley and completed in 1927. The aim was to supply drinking water for the increasingly populated area to the south. You can loop the reservoir for a nice gentle run or follow the longer Taff Trail up the western shore.
