Croaghaun, Achill Island

4.3
#8 of 8 in Parks in Achill Island
Croaghaun is a mountain in County Mayo, Ireland. At 688 metres, it has the highest sea cliffs in Ireland and Great Britain as well as the third highest sea cliffs in Europe .
Croaghaun is the most westerly peak of Achill Island, and its highest mountain. Its cliffs lie on the northern slope of the mountain. The cliffs at Croaghaun can only be seen by hiking around or to the summit of the mountain, or from the sea. They are part of a sequence of sheer rock faces which start south of Keem Bay and loop around the uninhabited north-west of the island, by Achill Head and Saddle Head, and east to Slievemore, occasionally dropping vertically into the waters of the Atlantic Ocean.
The Croaghaun cliffs are home to two families of peregrine falcons . September and October are the best time to see the fastest creatures on Earth here, as they teach their young to fly. Metamorphic, quartz-laden gems may be observed, along with Mediterranean heathers and the waters of the Atlantic. It is common to see shoals of bottle-nosed dolphins and basking sharks, once a source of revenue for Achill Island . Porpoises are found in large numbers. Killer whales, humpback whales, and other whales have been sighted.

  • The start from the end of the Keem beach car park is steep. Your calves are going to be in high demand; Just look at the level curves on the Ordnance Survey Mayo Map No.30! Once the ridge is reached via one of the many runs, the crossing will take you to the various headlands, the highest peaking at 332 meters. From here you have a beautiful view of Achill Head and, of course, the Croghaun opposite. This is where you really realize the difficulty of the company if you want to go to its top. The slope is extremely steep. Be careful to pinpoint where you're headed. There are plenty of sheep tracks, borrowed or not by hikers. It is easy to get it wrong when you try to get around muddy areas or other difficulties of the terrain. Hiking shoes and walking sticks are highly recommended as it is easy to twist an ankle. Resist the temptation to descend to the two corrie lakes because there is absolutely no path and the progression is difficult and slow as one walks in the heather and there are holes, even crevices. Stay on the side where the ground is firmer. For those who are apprehensuting and want to take a simple walk, you can just make a round trip to the watch tower, very visible from below. For those who want to pin the Croghaun to their list, the easiest access is to leave Lake Acorrymore which is located 200 meters above sea level (it is possible to park there) but if it is the proximity of the cliffs that tempts you, you must leave Ke em Strand but it's much longer. Avoid climbing if the weather conditions are not favourable (fog, strong wind)... Anyway, if it's to see nothing at the top, what's the point!?

  • Possibly the most beautiful place in the world.
  • We got beautiful views from the top of Croaghaun. Very tough hike from Keem bay as 0 to 688 mnm but views were worthwhile. Extremely steep towards the top.
