Full Disclosure: This area is a destination spot for me. I personally have never climbed in Ireland, but know that there are many spots with great rock available for climbing. I hope not to offend local climbers and will certainly secede the future of this area to those who know more than me. My only hope is to get the ball rolling in gathering more information about the climbing potential of this great country.
From the states you'll take a boat or a plane across the Atlantic Ocean and make your way to some of these great spots.
