 The walk from "Kate Kearney's Cottage" (at ), to the full "Head of the Gap" (at ) is 6 kilometres and takes circa 1 hour (and another hour for the return journey back to "Kate Kearney's Cottage").While not as well known as other Irish rock climbing locations (like Ailladie, Fair Head or Dalkey Quarry), various Old Red Sandstone cliffs and crags along the Gap of Dunloe are used as locations for rock climbing, and over 107 routes are listed and graded in the "Irish Climbing Online Wiki".There are only two crags on the east side of the valley, namely "Céim" and "Bothán", with most of the crags being in the north-west side of the valley, near "Brennan's Leap" (the cliff at the western shore of Coosaun Lough) / the "Wishing Bridge" (the stone bridge between Coosaun Lough and Black Lake).
