Postbridge & Fernworthy Reservoir loop — Dartmoor National Park

Embark on the Postbridge & Fernworthy Reservoir loop, a difficult 13.5-mile (21.7 km) hike in Dartmoor National Park that challenges you with 1256 feet (383 metres) of elevation gain over approximately 6 hours. This route guides you through varied terrain, from untouched moorland to dense forest paths and the tranquil shoreline of Fernworthy Reservoir. You will experience a notable steep ascent to Hartland Tor, offering expansive views, and traverse areas that can be wet and boggy, especially near river headwaters, so be prepared for uneven ground.

Starting from the picturesque hamlet of Postbridge, this loop is considered difficult primarily due to its sustained distance rather than extreme climbs, though the ascent to Hartland Tor is a significant feature. While seasoned hikers might find the overall elevation manageable, the length requires good fitness and sure-footedness. Plan your visit to account for potentially wet conditions, and ensure you have appropriate footwear for the mixed surfaces you will encounter throughout the day.

This trail is rich in history and natural beauty, featuring several prehistoric sites like the Grey Wethers Stone Circles, a well-known double stone circle. Fernworthy Reservoir itself is a haven for wildlife, home to rare species such as the marsh fritillary butterfly and various birds. When water levels are low, you might even spot a submerged clapper bridge that once crossed the South Teign River, adding another layer of historical intrigue to your journey through Dartmoor's diverse landscapes.
