The waterfall is one of the few in the UK that discharges its water directly onto a sandy beach.
The name 'Tresaith' translates from Welsh as 'Town of the Seven,' referring to a local legend about seven daughters of a king.
The cliff face at Tresaith shows evidence of complex folding and faulting characteristic of the local bedrock geology.
The waterfall's volume is highly dependent on recent rainfall levels, occasionally drying to a trickle during prolonged dry spells.
Tresaith Waterfall is a coastal cascade where the Afon Saith flows directly over a cliff onto the sandy beach of Tresaith in Ceredigion, Wales. The waterfall drops approximately 30 feet from the cliffs onto the shore at high tide, though it is best viewed when the tide recedes to reveal the sandy cove. It marks the endpoint of the Afon Saith stream as it exits the valley. The surrounding geology consists of ancient sedimentary rocks typical of the Cardigan Bay coastline. The site is accessible via the Wales Coast Path, which traverses the clifftops above the beach. As of July 2026, the area remains an open-access natural site maintained as part of the local coastal environment. It is a prominent feature of the Ceredigion Heritage Coast.
From the beach at low tide, looking up toward the point where the stream meets the cliff edge.
Check the local tide tables before visiting; the waterfall base is only accessible for close-up viewing at low tide.
Wear sturdy footwear suitable for walking on wet, uneven sand and slippery rocks.
Approach the waterfall from the beach rather than attempting to scramble down the cliffs.
Attempting to climb the cliff face near the waterfall, as the rock is unstable.
Respect the natural environment; do not litter or disturb the cliff-nesting birds.
