Cairnstrath
Noirmoutier-en-l’Île, Pays de la Loire, France
UNVERIFIED — Cairnstrath is an exact named France Atlantic/Channel dive site established by current operator, club or current exact-site evidence. Its displayed coordinate is a deliberately rounded locality marker, not the underwater site. Access, identity, depth and conditions require a current local briefing; this is source-backed desk research, not field verification.
