Gillies Trail and Waterfall in Caegarw, Mountain Ash. Not many people are aware of the path that leads up to the mountain behind Caegarw and the impressive waterfall that is only a short 10 minute walk from the start of the trail. The path is accompanied by a beautiful river which follows alongside for a good part of the trial and there is a fair share of wildlife to spot too! If you’re looking for a new place to visit in Mountain Ash or a place to go with your dogs off the lead, this is ideal!

Lluest-wen Reservoir was constructed in 1898, but came to national attention in 1969 when a major leak caused an evacuation of residents down-valley while emergency repair work was carried out. Back in 1929 the place set a maximum daily rainfall record for Wales, with 211mm of rain recorded. You have been warned!
