“Great place! Nice staff, the equipment is well maintained, the selection of food and drinks is a nice addition and the prices are well aligned”
“My main climbing gym, lot's of routes to do, people here are friendly, music is good, drinks are affordable. Routes can be a tad bit challenging for beginners, even the "easy" ones…”
“…The training area is pretty spacious and has lots of equipment as well as 2 good sprays, the angles are very close though (30° & 35°) so not much variety there, other than the holds.”
