One hidden gem candidate is a smaller waterfall in Conwy county that packs a punch for what else it offers: as well as a very large plunge pool, alongside it is a slightly mysterious cave.

Suddenly, a man in a red T-shirt and black trousers appears and begins crawling into a small hole or cave in the waterfall. To the astonishment of the onlookers, he disappears completely from sight.

The cave, adorned with icicle ceilings ... For nature enthusiasts, the majestic Frozen Waterfall and Pin Valley National Park, home to diverse wildlife, promise a serene and scenic retreat.
