Cistercian monks, beaches and seals. What more could you ask?
To get to Caldey, take the small passenger ferry from the harbour in Tenby (Pembrokeshire). As of this week, it’s £11 for adults and £6 for children, and takes about 20 minutes. Note: no boats on Sundays.
When you’re on Caldey, you can walk up to the lighthouse at the far tip of the island and look at the seals on the rocks below, you can go and (very quietly) watch the monks’ chanting service, you can buy perfume (which used to be made by the monks, but I think is now outsourced), you can explore ancient St. Illtyd’s church and see the ogham writing there, you can loll on the beach with a picnic, you can see remains of prehistoric creatures in the tiny museum/post office … for such a small island, there’s an awful lot to do!
