St Tudwal's Island West
St Tudwal's Island West is a rocky island rising steeply from the sea off the Gwynedd coast, topped with a lighthouse that helps guide ships. The western island features dramatic cliffs, caves, and jagged rocks, while the smaller eastern island has gentler slopes covered in grass and holds the remains of an ancient priory.
The islands are connected to Saint Tudwal, a 6th-century monk who is believed to have founded a hermitage here and made it a pilgrimage site. The priory was first recorded in tax documents from the 13th century and served as an important religious retreat on the Welsh coast for centuries.
The islands are named after Saint Tudwal, a monk believed to have settled here in the 6th century and made it a place of prayer and refuge. The remains of the priory on the eastern island still reflect the quiet spiritual role this place held for religious communities centuries ago.
The islands are best reached by boat from Abersoch or nearby ports, with trips taking just a few minutes. Plan visits on calm days with light winds, and always check tide times before going, as currents between the islands can be strong during certain times.
The western island is privately owned by Bear Grylls since 2001 and its lighthouse remains actively used today to guide ships through Tremadog Bay. Grey seals are commonly spotted resting on rocks around the islands and often follow boats and paddlers out of curiosity, creating memorable wildlife encounters.
