Ninja & Obstacle Gyms in London

Only one place on this list is built just for the course. CTC Obstacles on Nelson St is the dedicated pick among Ninja & Obstacle Gyms in London, with adult obstacle-race training, kids' ninja classes and weekend open gym drop-ins from $18.80.

The other three tuck a course inside a bigger park. The Factory on Kellogg Lane puts its warrior course in the Hero Room beside four 145-foot zip lines, and has a licensed bar for the grown-ups. AeroSports on Wharncliffe Rd S adds Ninja Tag and runs GLOW Night on Tuesdays at 4 pm. Funvilla on Commissioners Road East pairs its ninja course with soft play for $23.99.
