Main image

Caldey Island is a small island off the south Pembrokeshire coast of Wales, notable for its long monastic history and an active abbey community that occupies much of the island.

Caldey has been a site of Christian worship since the early medieval period, with successive religious communities on the island; the present abbey buildings date from the modern era and house a contemporary monastic community.

Located off the south coast of Pembrokeshire near the seaside town of Tenby, the island is reached by a short boat crossing and lies within the Pembrokeshire coastal landscape.

  • Access: Daily visitor boats operate from Tenby during the main tourist season; access can be limited outside scheduled services so check timetables in advance.
  • Visitor etiquette: The island has an active monastic community; visitors should observe silence and respect areas reserved for the monks and their routines.

What to See #

  • Caldey Abbey: A working monastic complex on the island that is home to a small Cistercian community and includes an abbey church, guest facilities and a small shop selling locally produced goods.
  • Walks and beaches: Coastal paths and sandy coves that circle the island and provide short walking routes with views across the sea to the Pembrokeshire mainland and surrounding islets.
