East Dartmoor is a real treasure trove of hidden granite outcrops, many of which are huge and dominating, particularly between and around the villages of Lustleigh and Manaton. Due to their locations often being hidden within dense woodlands, many of these grand rocks have failed to get a mention in the Dartmoor Literature.
Situated within a small copse on private land near to the hamlet of Horsham to the east of Manaton can be found a giant outcrop of rock, its broken but nonetheless compact appearance resembling a huge block that lords over the dwellings below. Several smaller outcrops are scattered through the trees here, some above and some below the main rockpile, suggesting the tor was even grander than it is today.
Despite its secluded location, its lower rocks can be viewed from the driveway below to the east where a public footpath runs up from Horsham Steps into Lustleigh Cleave. A truly lesser-known gem its existence is only indicated on old OS maps where a small gathering of rocks are marked, but Horsham Tor covers a much greater area than that which is shown.
