Why dive here
With 112+ marine species recorded in the area - including blue whales, dolphins, dwarf minke whales, humpback whales and ocean sunfish (mola mola) - Three Sisters offers some of Scottish West Coast's richest diving.
The Three Sisters, tucked away on the Scottish West Coast, offers a surprisingly gentle dive. We drop down to a maximum of 19 meters, a comfortable depth for those just getting their fins wet. What you'll find here isn't dramatic drop-offs, but instead a collection of kelp-draped boulders and small gullies. Look closely amongst the fronds for wrasse, blennies, and the occasional crab scuttling past. It’s a site that rewards a slow pace and an observant eye, perfect for beginners honing their buoyancy or anyone looking for a relaxed exploration of the shallows.
