The club dived one day in Clew Bay in Oct 2010 (Stephen McMullan AD assessment trip)


Overshadowed by the diving available at Clare Island and Inishturk, Clew Bay provides a useful alternative in strong south westerlies if you can’t get out to the islands.

There are excellent launch facilities at Old Head and amazing views of the bay and Croagh Patrick.

The sites are unspectacular and best used for training and assessments in foul weather.

Killary Harbour provides a close alternative once you have your fill of Clew Bay.


The advice received was that there are reefs off Old Head which are “supposed” to be nice dives in 13-18m and there is a rock called the “perch” north east of Old Head marked by a green buoy with depths down to 27m.

In practice we explored several reefs which were found to be mediocre and missed the “perch”.
