Analysis of information sources in references of the Wikipedia article "Twelve Bens" in English language version.
The finest rock formations in the Twelve Bens are found in the south wall of Gleann Eidheanach (Glen Inagh), running from Binn an Choire Bhig to Mám na bFhonsaí, east of Binn Dubh (L808530).
Even if you had to crawl across bogs to get to them, it would be worth it as the nine [should be six] peaks which form the Glencoaghan Horseshoe provide some of the most exhilarating mountaineering on this island.
The formula is preserved in the range known in English as "The Twelve Bens of Connemara", although the names of the exact twelve peaks are no longer known
