Row, Rope-Up, Traverse: The Adventures of ‘Sea Stack’ Climbing in Ireland

Waves crashed on a rocky shore. The tide was high and still rising. “Jump in the boat!” my guide shouted.

Soon we were bobbing on a stretch of cold water. Kelp swirled below. With climbing shoes and a backpack on I leaned forward to view a rock pillar looming ahead.

It was a Sunday morning in Ireland. I was on the country’s west coast to explore and test gear with a group from Columbia Sportswear and three local guides.

“Careful stepping out,” my climbing guide, Iain Miller, noted. He steadied the raft against kelp-covered rocks. “The brown slime is slippery.”

Our objective was an 80-foot sea stack. Like a stranded ship, the blocky formation was beached just off land. Its flat top, a summit surrounded by water, was a goal of the day.

Sheep chewed on green hills back on the shore. The ocean stretched away, a dark plane under a sunny sky.

It took some serious gear — pack rafts, paddles, climbing shoes, helmets, webbing, and 300 meters of rope — but our guides from Unique Ascent had a plan.

We’d boat to the sea stack, climb up one of two routes on its face, then as an adrenaline bonus the climbers would take an elevated Tyrolean traverse back to dry land.

Climbers wait to ferry to a stack

I’ve long been intrigued by sea stack climbing. Creaking pillars of stone stranded over ocean water are rare and exciting rock climbing objectives.

In Ireland, where the west coast stretches for hundreds of miles, sea stacks dot the view. The stone on our climb, a formation called Berg Stack, was solid and surprisingly dry.

As our group possessed varying abilities, our introductory sea stack was far from extreme. After the boat ride, I waited on a ledge as the other climbers were ferried over.

Ferry to base of the route via pack raft

Two top-ropes hung from above; the guides had led the stack and set up the routes before we arrived. I climbed around on the ocean stone while the group gathered on a ledge.

The tide was rising. Time to climb.

Cracks and grippy handholds made for an easy but fun ascent. Once tied in I climbed a crack and then traversed onto a face for added challenge. The pitch was all the more enjoyable because of the setting and an ocean breeze.

Nuts for anchors atop Berg Stack

On top, it was back into the sun. Water and wind had scoured the stone clean — this was not a dank bird-covered sea rock but a summit the size of a basketball court.

We climbed up one by one, a guide belaying from the top. Climbing nuts and hexes, jammed in cracks, served as anchors for the webbing and ropes.

Heading up…

At the prow of the formation ropes streamed horizontally toward land. One at a time we clipped in, lowered as the lines stretched, then pulled and zipped back to the other side.

A seal bobbed in the water while I waited for the next climber to come. His gray snout and whiskers, curious, turned our way. Rock climbers on an ocean shore were indeed a rare sight among the kelp and crashing Irish waves.
