The granite used to construct London Bridge in the 19th century was quarried from the slopes immediately surrounding Haytor.
The Haytor Granite Tramway, built in 1820, is one of the earliest examples of a horse-drawn railway using stone tracks.
The rocks are composed of coarse-grained granite containing large feldspar crystals, a geological feature known as 'porphyritic granite'.
The site acts as a major drainage divide, influencing the headwaters of several streams flowing into the River Teign.
The granite outcrops exhibit 'tors' formation, a process where chemical weathering exploits vertical joints in the rock.
Haytor Rocks consists of two prominent granite outcrops located on the eastern edge of Dartmoor National Park. These tors were formed by the cooling of magma deep underground approximately 280 million years ago, followed by millions of years of erosion. The site serves as a geological landmark and a primary access point for the surrounding moorland. An abandoned granite tramway, featuring unique stone sleepers, runs from the rocks down toward the village of Haytor Vale. The site is a managed area within a protected national park landscape. Visitors can climb the granite stacks to gain views across the Teign Valley and toward the South Devon coast.
The gap between the two main granite stacks provides a framed view of the surrounding rolling moorland.
Wear sturdy, waterproof hiking boots, as the ground surrounding the rocks is frequently boggy and uneven.
Carry a physical map and compass, as mobile signal is unreliable across the moor and mist can descend rapidly.
Layer your clothing regardless of the season, as the exposed summit experiences significantly higher wind speeds than the car park.
Attempting to climb the granite stacks during wet or icy conditions, as the stone becomes extremely slippery.
Stay on marked paths to prevent erosion of the fragile moorland flora; follow the Countryside Code by keeping dogs on leads near livestock.
