Tresaith (otherwise Tre-saith) is a coastal village in Ceredigion, Wales, between Aberporth and Llangranog. It is linked to the former by a two-mile section of the Ceredigion Coast Path, part of the Wales Coast Path. Tresaith is within the Ceredigion Heritage Coast which offers extensive walking and views. There is an abundance of wildlife and flora. Many kinds of seabirds can be spotted and regular sightings of grey seals and dolphins are made.
Until the mid 19th century it consisted of two dwellings, a thatched cottage and the Ship Inn. The Parry family who ran the inn were shipowners and their first vessel, the New Hope, was built on the beach at Tresaith in 1827. Later, several smacks of about 25 tons operated from here, bringing in coal, limestone and culm. In the last few decades of the 19th century the village became popular as a seaside holiday destination and contemporary newspapers referred to it as the Second Brighton.
