Here you'll cross over the Afon Leri river at the Dyfi estuary at Ynyslas. This area is part of the Ynyslas National Nature Reserve, a huge area where at low tide, the remains of an ancient submerged forest with stumps of petrified oak, pine, birch, willow and hazel are exposed on the beach.

Great walk along the beach in Borth. A lot quieter than nearby Aberystwyth.

Meticulously whittled, this rather impressive wooden eagle is definitely worth stopping. Only a stone's throw away from the beach by the way
