Eastwater Cavern

Eastwater Cavern lies in the Mendip Hills near Priddy, Somerset, formed in limestone where streams carve underground passages. The cave’s entrance sits among boulders, leading into a wide bedding-plane sloping forty degrees down. Further in, the tunnel drops towards a canyon, while lower levels require pitches and climbs to reach. Primrose Pot plunges fifty-seven metres straight down, one of the deepest vertical drops in the Mendips. The water flowing through the cave emerges four kilometres south at Wookey Hole Caves, eighteen metres lower than the entrance. Explorers first dug here in April 1902 under Herbert E. Balch, with help from the Wells Natural History Society. By February 1903 they had traced the streamway to the cave’s bottom. Later digs opened Dolphin Pot in 1940 and Primrose Pot in 1950, while the West End series was found in 1983. Flooding in 1910 made parts unstable, halting access for three years. A rock-fall killed a caver in 1960, and another blockage trapped the Dolphin ladder pitch until it was reopened in 1966. Visitors walk through boulder-choked passages and traverse steep slopes to reach the canyon. The lower sections demand careful climbing down pitches like Primrose Pot. Water echoes along the streamway, feeding the resurgence at Wookey Hole. The cave’s unstable boulder chokes remain a reminder of its shifting nature. Each section tells part of the story of discovery and danger underground.
