Wild Swimming

Lunan Bay

Lunan Bay is one of Angus's finest beaches — 3km of clean, north-facing sand between Red Castle and the Lunan Water mouth, with a distinctly wild, uncrowded character. The red sandstone ruins of Red Castle (13th century) stand on the dune edge above the northern end of the bay. Cold North Sea exposure, zero crowds on weekdays, and the ancient castle backdrop make this one of eastern Scotland's best wild swim beaches.

Common questions

Is Lunan Bay a good wild swim beach?
Excellent for experienced open-water swimmers — clean, uncrowded, and dramatic. The rip current near the river mouth means beginners should stick to the central section of beach.
