This is a circular walk of just over 5 miles with some moderately steep gradients.
The walk starts on the North Cliffs at Deadman's Cove and follows the coast path to a second cove of the same name. This was probably not a good place to get shipwrecked!
The route follows the Coast Path which is diverted around the site of the 2011 cliff fall at Hudder Cove that went viral on YouTube.
At Hell's Mouth, the route turns inland through a river valley and along a farm lane to the Gwealavellan cross. The walk then descends into the Red River valley at Menadarva.
The walk then follows the bridleway along the Red River through the nature reserve. The Red River is so named due to the ochre (iron hydroxide) that gets deposited when iron dissolved in the acidic water draining from the mines gets diluted in the river water. The water draining from the mine at Dulcoath is now filtered through a reed bed which has dramatically reduced the mineral content in the river water, though the river bed is still orange from the ochre deposits. The bacteria in the reed bed do some nifty biochemistry to tie up the minerals from the mine drainage into harmless insoluble compounds. There is even talk of the minerals being commercially recoverable from the reed beds in the future, which seems like a big step forward from pollution.
The bridleway emerges in Coombe, and the circular route is completed to the North Cliffs via a footpath.
The walk is available as a guided walk app for Android and also available in the iWalk app for iPhone.
There are also a few other walks on the Portreath-Godrevy heritage coast on the iwalknorthcornwall website.
