On The Rocks is at Kingston Mills next weekend! This is a very pretty little crag by the river in Kingston, just outside town. Join us for an Intro session on Saturday or Anchor Building on Sunday, or even a Top-rope Meet-up on Friday afternoon!
This is one of only two weekends at the site this summer, so if you're keen to get introduced to the crag and learn a few new skills, don't miss it! Registration is through our calendar at www.ontherocksclimbing.com
