The Trewavas area offers some of the most enjoyable and accessible climbing on Cornwall's South Coast. Routes are mainly single pitch, up to 20m in length, and low to middle-grade but with several harder lines. Trewavas granite is finer-grained than that of the Land's End Peninsula. Cracks in the rock can sometimes be disconcertingly blind but protection is ample. The rock is excellent throughout, although there is some loose rock in places at sea level. The cliffs are generally steep and the climbing can be strenuous. Most climbs lie high above the sea on steep-sided buttresses, although there are some worthwhile climbs at sea level. Attractive surroundings, a sunny outlook, and fine sea views are compulsory; all of which make Trewavas one of the most popular venues in West Cornwall.
From the A394 Penzance to Helston road, turn onto the minor road signed to Rinsey at the village of Ashton. Follow the signs to Rinsey hamlet and take a track to the National Trust car park. Follow the coast path down to an old mine building and take the path that gently climbs up the hill (not the coast path). Follow the path which skirts walls and open ground past another cluster of old mine buildings. The crags are located near here.
