About
Steep Holm is a nature reserve, bird sanctuary, and Site of Special Scientific Interest due to its rare plants, including the May flowering wild Mediterranean Peony. Here you can find peace and quiet with fantastic 360 degree views of the Bristol Channel and the Somerset and Welsh coastlines. Walk the cliff tops, ramble around the military buildings, explore the underground ammunition stores, get involved with an archaeological dig, or simply while away the day on a rugged and beautiful island. 10-12 hours to explore.
The terrain is rough, with a moderately steep path to the summit, so may be unsuitable for those unsteady on foot and very young children. Depending on the time of year, rare and unusual plants, including the wild Mediterranean Peony, large colonies of gulls, Cormorants, Peregrine Falcons, Ravens, other resident birds, and Muntjac Deer, may be seen. Victorian gun emplacements with their original seven ton cannons, Second World War gun emplacements, and underground ammunition stores. A German field railway recycled on Steep Holm to take wartime ammunition to the summit. An on-going archaeological dig – visitors are welcome to help. An exhibition room with artefacts found on the island, where you can follow the story of Steep Holm and its many occupiers.
