Indoor climbing at The Tower climbing centre, Leicester. The climbing wall is inside the sports centre, which can be seen by the water flumes that come out of the building.
There is a bouldering area with a cave, and a roped climbing with 15 panels, some lovely overhangs and steps. http://www.thetowerclimbingcentre.co.uk/
Entry before 6pm is cheaper, so we usually arrive around 5.50pm. New people welcome!
