On a calm day, Tresaith beach has a tropical feel, whilst at other times westerly winds bring much more dramatic scenes of waves crashing against cliffs and rocks. The unusual feature of the northern end of the beach is a result of glacial activity when a glacier blocked and diverted the route of the river Saith, causing it to cascade in a waterfall directly onto the beach. There are plenty of rock pools to explore. They are full of interesting creatures and the rocks are covered in limpets, barnacles and mussels.
Tresaith beach is a popular location for surfing, and also has a busy sailing club with racing on most Sundays throughout the season.
