We don't currently have a regular climbing night but here are some links to local indoor climbing walls.
Directions and info for the wall can be found here. If you're trying to find it in the dark then look for the sports hall on the right as you go up New Road - it's just after the school and bus stop. Go through the main doors, left, right. The wall has a bouldering area and higher section with fixed ropes. Harnesses are available for hire, or you can boulder.
One for the summer, if the weather looks good.
