Inner Stack (From SE) © cearbhalld

Crag features

This island lies about one mile north of Howth Harbour, and the known climbs are to be found on the big quartzite stacks at the south east. corner of the island. The climbs, typically, are steep but with good holds. It is a great venue for a relaxed and different climbing day out.


Approach notes

RESTRICTIONS. Gulls, guillemots, and other seabirds nest on the Stacks, which should therefore be avoided from the beginning of April until mid July.

The Outer Stack is now permanently inaccessible because of the density of the gannet population.

Access is by boat from Howth Harbour. Check out for regular sailings.
