About Caldey Island#

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.

How to Get to Caldey Island#

Ferries run from Tenby (Pembrokeshire) to Caldey Island in summer months; the crossing is short and timetabled. Passengers disembark at the island’s quay and follow clear footpaths to the monastery and walking routes.
