This is a circular walk of just over 5 miles with some quite long but not excessively steep gradients.
The route follows the high cliffs from Hell's Mouth to Navax Head. It then passes some chilly north-facing coves with very steep paths, frequented only by the hardiest of naturists, before crossing the heathland reserve of The Knavocks. Although the name might sound like somewhere that naturists might catch a chill, it’s actually from a Cornish word thought to mean “Autumn dwelling”.
The walk continues alongside the crumbling cliffs to reaching Mutton Cove where there is a large grey seal colony. There are excellent views of the seals from the coast path, though care must be taken not to disturb them as they are scared by noise and rapid movement possibly thanks to our spear-wealding ancestors.
The path continues around Godrevy Head with excellent views of the iconic lighthouse and across St Ives Bay. Basking sharks and ocean sunfish have be sighted from the headland and pods of dolphins are quite regularly seen.
The path passes along some small coves before turning up the Red River Valley through the Gwithian Towans. The towans provide an important habitat a range of wildlife including glow-worms.
The return to Hell’s Mouth is along an ancient pilgrimmage route as far as the Gwealavellan cross and then via the wooded valley below Carlean.
The walk is available as a guided walk app for Android and also available for Apple iPhones and iPads via the iWalk app.
There are also a few other walks on the Portreath-Godrevy heritage coast on the iwalknorthcornwall website.
