The northern end of the Ceredigion Coast Path extends to the Dyfi Estuary National Nature Reserve at Ynyslas.

Ecology

The Dyfi National Nature Reserve and the Ynyslas Sand Dunes are situated where the mouth of the Afon Leri joins the Dyfi Estuary at Ynyslas. Cors Fochno is situated to the east beyond the Afon Leri. 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.

Railway

From 1867 Ynyslas had a railway station on the Cambrian Railways, with sidings serving the riverside wharves. The Plynlimon and Hafan Tramway proposed to create a narrow-gauge line to the wharves in the 1890s but this was never built. Ynyslas railway station was closed by the London Midland Region of British Railways on 14 June 1965.

Recreation

Borth Rowing Club stores its boat at, and launches from the Ynyslas Boatyard on the banks of the Afon Leri. The 18 hole golf course at the Borth & Ynyslas Golf Club stretches from Borth to Ynyslas. Swimming is not allowed at Ynyslas in the sea or estuary, due to the dangerously strong currents. Ynyslas was the home of the Aberystwyth Beach Cricket Society, under the name the Ynyslas Oval.
