Outer Rock - West Coast
Outer Rock sits off Ireland's west coast, a straightforward intermediate dive down to 24m. It's a predominantly rocky reef, where we've often found conger eels tucked into crevices and plenty of wrasse darting through the kelp. Visibility can be a bit variable, but on a good day, it’s a solid dive for those looking to experience typical Irish coastal diving without anything too challenging.
