Knockan Crag is a series of cliffs designated as a National Nature Reserve. Knockan Crag holds the key to an amazing story of colliding continents and scientific intrigue. The low cliff of Knockan exposes rocks that set the scientific world ablaze in the 19th century, with the discovery that a slice of old rocks sits on top of much younger ones. The Moine Thrust, as it is known, was created by the force of two continents crashing together many millions of years ago. Facilities include a car park, toilets, visitor centre and trails ranging from easy to strenuous.
