The parking spot given to start the route is free but not the nearest to the route. There is plenty of road parking nearer the start of the actual lake.,

Cambrian Colliery was the site of two major mining disasters leading to major loss of life. This memorial is a tribute to those who lost their lives and a reminder of the terrible toll taken by this industry.

Cwm Clydach Countryside Park is an oasis of calm for wildlife with stunning views that has been created from the blackened scar of a coal mine. Walking alongside the lakes offers the chance to spot Kingfishers, herons, butterflies, newts and more. The two lakes are referred to as the “top lake” and “bottom lake” and there are also waterfalls. For refreshments, there is an on-site cafe.
