• Bouldering needs no course, so kids can drop in and climb the 4.5m walls; rope climbing needs belay skills or a taster course first
• Six auto-belay machines cover 28 routes graded from an easy 3c up to 7b
• All gear for rent, from shoes and harness to rope, with no booking needed; bring a padlock for the lockers or buy one at the desk

A large climbing gym on the Gaswerk industrial site, with about 330 rope routes on walls up to 17m and around 260 boulders, indoors and outside.

Kids can drop in to boulder on the 4.5m walls; climbing on a rope needs belay skills, so first-timers book a taster course. All gear rents at the desk, and there's a bistro and lounge.
