Cwm Lliedi Reservoirs are located in Swiss Valley, just North of Llanelli. The two reservoirs are a popular destination for dog-walkers, ramblers and wildlife enthusiasts. There is a 2-mile woodland walk surrounding the reservoirs so there are plenty of birds and wildlife to see.
The eastern path which is not suitable for wheelchair user has a good gravel surface but can be muddy at times and stout walking boots are recommended.
