Standing guard at the entrance to Clew Bay, Clare Island is a tiny mountainous island in County Mayo. Famous as the home of the pirate queen Grainne Uaile (Grace O’Malley), today just 145 people live here year round. But the diminutive island is a haven for adventure lovers as Outsider’s editor Roisin Finlay discovers.

I’m standing on the top of a 30-foot sea stack. The Atlantic in all her watery glory stretches out around a cotton wool grey sky. The pile of rock is called the Bird’s Nest thanks to the toupee of grass which grows on its top, dancing and waving like a wayward comb-over in the light breeze. It’s one of those calm mild days. A ‘pet of a day’ as my mother would say.

I take a few deep breaths and mutter some clichéd ‘psyche-me-up’ expressions before I jump. A guttural roar fills the air before I blast into the sea, light disappearing and a storm of water and bubbles rushing past my face. Then the blackness recedes and I surface into the light. Grinning. I did it! I am coasteering off the northeast coast of Clare Island in Co Mayo.

Coasteering on Clare Island:

The idea behind this activity is simple. You explore a section of coastline through a combination of swimming, clamouring along rocks and jumping off certain points. It’s a basic concept but it can be dangerous so it’s important to use a qualified guide.

We’re under the watchful eye of two guides from Clare Island Adventures, a collective which organises accommodation, transport to the island and adventure activities while you’re there.

The Best Irish Islands to Escape to

For both comfort and safety, our guides Ian and Susan have kitted us out with a helmet, buoyancy aid and not one but two wetsuits for extra warmth.

The water is about 10° Celsius and despite dreading being freezing for the trip I am completely fine. In fact, I forget about the cold pretty quickly as I am distracted by the stunning scenery which pans in soft lines of grey, blue, purple and green from Achill Island to Croagh Patrick.

Our route also brings us into a sea cave. The atmosphere is ethereally peaceful until a cormorant flaps suddenly from the darkness, indignant at the intrusion no doubt. Some of the group swim down an ever narrowing and darkening cavern but I’m too spooked so I find a perch and admire the colour of the rocks and take in the sunlight playing tricks through the crystal clear green water. I can only imagine what the light show would be like on a clear sunny day.

The Ultimate Irish Adventure Bucket List 

When we regroup we recommence our rock clamouring and leaping into the sea. The trip is cleverly organised so that the jumps increase in height gradually until finally we reach the Bird’s Nest. Ian, our gentle giant guide, makes sure everyone knows that there is no pressure to jump.
