Extremely cozy and relaxed atmosphere, very nice people, great variety of cool bouldering problems, lovely choice of snacks and cold drinks. Big difference to other gyms: the walls don't have any grip; completely new experience/climbing style for me!

Really the only bouldering place I've been to in Germany, and one that I like. Quality of service is excellent. The bouldering elements themselves are well placed with mats, and there are free climbing devices that you can set with an app. My only pet peeve is that it's expensive, in comparison to other places near Frankfurt at least. But that too is reasonable

Very nice Bouldering gym. Clean, warm, good music and interesting problems. Prices are okay, especially if you come before 4pm. New routes are set weekly so you never get bored. Definitly recommend going here.

Nice atmosphere, plenty of interesting routes with all sort of difficulty, pretty good bouldering place.

Great place and ever greater atmosphere! Here you can not only climb, but also have a cozy and nice place to chill. It has a even a bouldering version of twister. The courses they offer are good and their team is always friendly and cooperative. In addition, their routes cover all difficulty levels, are well planed, fun and changed very often. Totally recommend to go by yourself or with friends.

The hall is very long, meaning that there are lots of routes - and, typically for bouldering, they're low enough that you can fall fairly easily if you absolutely have to. The atmosphere is generally relaxed - I would consider coming to some of their polish up courses, which are offered at different times during the month, if you want to step up your game.

Nice staff, great atmosphere and a good training area in addition to the bouldering. Lots of boulders to choose between. I would say most overhang, but also some slab.

Lived in four countries more than 10 cities. This is the best bouldering place so far. Routes are reset frequent enough to be fun but not too frequent that you can’t come back to work on the same thing. Friendly staff and relaxed atmosphere ;) nice climbing community

Very nice place whether you are going with your friends or family. Child friendly as well, so you can do birthdays there

Always enjoy visiting Boulderhaus, amazing place. Taking away one star because some of the staff doesn't know first aid. Otherwise amazing!

Great bouldering place with a really nice atmosphere, bar with food and drinks make it a good place for hanging out with friends while doing some exercise, friendly staff.

Nice routes, spacious bouldering gym with a good atmosphere

Very nice place. Very well designed in this old industry building. It offers a great selection of training utensils and great routes for every difficulty. However the walls are a bit slippery so going on friction is not very easy.
