The Llwybr cerdded mynydd (mountain walk trail) is a series of six caches that cross Mynydd Maendy, Mynydd Portref and Mynydd Meiros.
A good OS map is needed to follow the footpaths and a good sturdy pair of boots is a necessity. Please keep to the footpaths at all times and do not climb over any fences.
All of the caches are 0.5L plastic box with space for swaps, so should be fairly easy to find.
