In addition to the mill, which was used for yarn production are here in the rock carved labyrinths to be about 4000 years old (Bronze Age). But nobody can say exactly. There are also studies that assume that they were made about 300 years ago with metal tools.

All hikes in Cornwall are extraordinary excellent. Still the Rocky Valley trip was one of my best walks ever. We did the hike with some friends and we all found the Rocky Valley breathtaking.

The Trewethett Mill ruins are the fascinating remains of a historic watermill near Trevalga and Trevalga Stream on the rugged north coast of Cornwall. The mill was formerly powered by the water from a small stream that flowed through the valley towards the Atlantic Ocean.

Today, the characteristic stone walls can still be seen at this spot, steeped in history and overgrown with coastal greenery. The ruin is hidden in the dramatic cliff landscape, a stone's throw from the famous coastal path.

St Nectan's Glen & Rocky Valley loop — Cornwall

01:51

Embark on the St Nectan's Glen & Rocky Valley loop for an easy 4.1-mile (6.6 km) hike through diverse Cornish landscapes. You will gain about 402 feet (123 metres) in elevation over approximately 1 hour and 50 minutes. The trail guides you through ancient woodlands, where the River Trevillet flows, before opening up to rugged coastal scenery with panoramic views of the Rocky Valley and the turquoise sea. You can expect to see the impressive 60-foot (18-meter) St Nectan's Glen Waterfall, a highlight of the route.

Good footwear, like walking boots, is recommended, especially since forest paths can become muddy after rain. The trail includes sections along the South West Coast Path, offering spectacular coastal vistas over Willapark headland. Be aware that some paths run close to unfenced cliff edges, so exercise caution. Access to the St Nectan's Glen Waterfall usually requires a small admission fee, which helps with its upkeep.

This loop is notable for its blend of natural beauty and historical intrigue. The dramatic Rocky Valley features ancient woodland and canyons, with the river leading to a waterfall that cascades into the sea. Keep an eye out for mysterious circular labyrinth carvings on the rock face within the valley, thought by some to be very old. You will also pass the ruins of medieval mills, including the 18th-century Trevillet Mill, adding a historical layer to your hike.
