Errisberg sits overlooking the North Atlantic with stunning, panoramic views out to sea of the Roundstone bog and Dog's Bay. Inland, well, on a good day, you can catch sight of the Twelve Bens. At only 300 metres high, Errisberg is not that high, but it’s big on attitude, and the views are simply awesome.

Derryclare is 673 metres high and sits just south of its bigger neighbour Bencorr, and both of them form two of the ’12 Bens of Connemara’. They are connected by a rocky ridge that offers great views in all directions.

At 711 metres, Bencorr is the second highest peak of the ’12 Bens of Connemara’, which has some of the finest walking in Ireland. The mountains are not very high, the highest being only 730 metres, but they offer wonderful hiking opportunities with super scenery and are a feast for the eyes. As with all mountains, however, treat them with respect and ensure you are properly equipped at all times.

A good hill to do, with beautiful views down over towards nearby Freaghillaun South and Inishbofin, which is further away in the distance. The going is quite hard with no real paths, so expect it to be boggy and rocky with ferns. However, the views are well worth it. You are best put to park at the harbour to walk this hill.

We took whatever looked like a path on the way up. On the way down things got clearer and made some other choices. You can take both paths or everything in between. Very enjoyable walk up the Tully Mountain.

The second highest of the spectacular Twelve Bens, Bencorr (Binn Chorr in Irish) is a beautiful peak. It's one of the highlights of the Glencoaghan Horseshoe, one of Ireland's great mountain routes. In Carrot Ridge, the mountain boasts one of Ireland's great rock climbing ridges too, with routes of varying difficulty.
