A dramatic geological feature, The Green Bridge of Wales is an arch naturally created in the rock as it wore away by the ebbing and flowing of the tide. Currently standing as an arch, it is expected that the top of the arch will eventually wear away leaving a stack of rocks in place. The Green Bridge of Wales can only be accessed through the Castlemartin Firing Range, so please call the Visitor Centre if travelling specially to check if the range is open. If you are making the trip, the chapel in the cliff, St Govans is nearby and is also well recommended.
