ⓘ Saint Tudwal's Islands


ⓘ St Tudwals Island Monastery

Saint Tudwals Islands are a small archipelago lying south of Abersoch on the Llŷn Peninsula in North Wales, at the western end of Tremadog Bay. They were apparently referred to as the Studwells in the early 19th century.

There are two main islands: Saint Tudwals Island West Welsh: Ynys Tudwal Fawr52°47′56″N 4°28′18″W and Saint Tudwals Island East Welsh: Ynys Tudwal Fach 52°48′19″N 4°27′43″W, plus the Carreg y Trai rocks.

The islands are known for their seal population. The western island houses the St Tudwal’s Lighthouse, and the eastern has the remains of a priory. The western island reaches 144 feet 44 metres and is the higher of the two.


1. Saint Tudwals Island East

Saint Tudwals Island East Welsh: Ynys Tudwal Fach is a grass covered, kidney-shaped island, about 550 yards 500 m in length and 220 yards 200 m in width. It was owned by author Carla Lane until her death in May 2016.

The highest point on the island is 125 feet 38 m above sea level. It is located just over 0.62 miles 1.00 km off the Llŷn Peninsula in Gwynedd. The nearest settlement apart from the lighthouse on Saint Tudwals Island West is Machroes. Small ships sail from the nearby town of Abersoch to take passengers to view the wildlife. The island is believed to be the original hermitage of Saint Tudwal, which is presumably where its name comes from. The remains of a priory, referred to in the 1291 tax rolls, can be found on its eastern side.


2. Saint Tudwals Island West

The West island was purchased by adventurer Bear Grylls and converted into a holiday home. On 22 August 2013 it was reported that he was facing a planning investigation by Gwynedd Council, after installing a slide into the sea. He has since taken the slide down, saying it was never intended to be permanent and that he would clear it with the council before using it again.
