Overview
Crab Island is a powerful, high-performance right breaking over rock reef off a small island just outside the harbour in the very touristy Doolin Village. In the 20th century this was the heaviest wave around, and it still packs a punch. The water is very clean, but the limestone reef below is razor sharp and can get shallow, and it is a long way back to the harbour if you get hurt or lose your board.
When It Works
The island picks up swell from southwest to west-northwest and is usable from 0.9 m / 3 ft to 3.7 m / 12 ft, which covers everything from head high to triple overhead. Spring and autumn are the standout seasons, though waves break here all year round. Mid winter tends to be spotty, mostly because the wave does not handle wind well.
Wind and Tide
Look for east-southeast offshore wind, with a workable wind window running from east to southeast. The reef breaks on low to mid tide, and a rising tide is generally the better call.
Local Tips
This one is for expert surfers on a shortboard or a gun. Expect a moderately busy lineup when it works: it is a staple for locals and the takeoff spot is fairly tight, so smiles and strategy go a long way on a good sunny day. It gets overlooked when it is a little bigger, largely because of the paddle.
Access
Park at the harbour and paddle out from the rocks. Do a shoulder day beforehand, because the island is further out than it looks.
