Along the coast near the village of Cregneash is an impressive collection of fissures cut deep into the cliffs. There is a pretty long walk downhill to the coast. Once you pass through the gate, you are entering the chasms and need to watch where you walk. There are well defined paths formed over time by lots of walkers, but take care over loose rock.
The Chasms are located in the southwest of the Island near the village of Cregneash. Go through Cregneash and up the hill. Parking at the top of the hill, but the rest must be walked down the other side of the hill towards the sea.
