Bull Rock
For a major expedition off shore for a group with the right boats and personnel, look no further than Bull Rock, 5km beyond the end of Dursey Island and some 15km from Garnish Pier. This very impressive rock rises almost vertically from the sea on all sides to a height of 80m and is topped by a lighthouse. There is a large archway right through the middle of the rock, through
which it is possible to take a dive boat, but watch out for the thousands of sea birds that nest on the cliffs! Although it is probably possible to dive in a tidal shadow, it makes sense to plan a dive here for slack water to reduce risks.
Excellent deep diving is assured here wherever you enter the water with the life running on well beyond safe diving depths. The helicopter landing pad, 60m above sealevel, was washed away by a wave during a storm some years ago, needless to say it needs to be exceptionally calm to dive here. There are two other offshore rocks nearby, the Cow and the Calf, equally impressive.
