I am the owner of this property & you have my permission to search here BUT YOU DO NOT NEED TO GO UP THE STEPS. Please, no searching after 10pm. The Dart Bridge referred to in the name of this cache goes over the River Dart nearby. The Dart catchment area covers 475 square kms from Dartmoor to Dartmouth. Just along the road from the cache is Russets Lane. If you go up here you will come to Higher Kiln Quarry, maintained by Devon Wildlife Trust. Quarrying for limestone here led to the discovery of a series of caves formed by the River Dart approx. 250,000 years ago. The lime kilns (visible) used local limestone to produce quicklime for agriculture & building in the local area. There is a useful information board next to one of the old kilns. The caves contained fossilised remains of hippo, rhinoceros, brown bear, lion, hyena, bison & straight-tusked elephant that used to roam the area. 16 different species are represented, forming the richest-known discovery of Pleistocene fossils in Britain. The caves are protected by the William Pengelly Cave Studies Centre. Each Wednesday in August the caves can be accessed via the visitor centre, with guided tours. They are closed to the public other than this. In winter, rare Greater Horseshoe bats hibernate in the caves. They can be seen at dusk on warm summer evenings - near the caves & in various spots around Buckfastleigh - when they emerge to hunt for insects. It is quite a sight.
