Tucked into the fairytale landscape of Tollymore Forest Park, The Hermitage is one of Northern Ireland’s most enchanting wild swim spots. A hidden plunge pool carved by the Shimna River, its crystal-clear waters shimmer beneath a canopy of ancient trees and moss-cloaked boulders. The deep, still basin—once a Victorian bathing retreat—invites brave swimmers to take a refreshing dip in its cool embrace, while the surrounding forest murmurs with myth and quiet magic. Easy to access yet wonderfully secluded, it’s the kind of place that feels like a secret—until you dive in. Just watch out for the resident otters—they love it here too.
