Is a nice place for bouldering, we decided to give it a shot, our first time ever. At fist we thought it looked kind of chabby as the outside building and the entrance aren't inviting at all! As we moved towards the inside bouldering area, it looked okay. The staff gave us some first time instructions and we imidiatly started off climbing. The walls are both suited to beginners and more advanced climbers, so there is fun for everyone. If you'd like to visit Graviton try to pick a day when it is not to crowed, cause then the walls are yours!

Very friendly staff, clean hall and challenging boulders. Had a great time!

Great bouldering gym! Nice wall, holds and good setting. Worth the visit.

Lovely bolder hall, with a nice variety of climbing routes of different levels. It's nice and quiet there. Not too many people so you don't have to wait till the wall is free. There is a nice bar with friendly staff and a nice variety of beverages. They also have a lot of games for when you want a break from climbing and these are free to use. They even have a pool and fussball table.

A very nice gym. Very friendly and helpful people. It is super close to the station. (Google Maps says it is a 20 minute walk, however it is a 5 minute walk in reality) The prices aren't too high at all, and they have discount for students and people below 18. I'd recommend this gym if you want to start bouldering, since they offer nice courses for a good price. (35 euro's excluding the admittance fee of ~10 euros for 4 fridays)

My favorite place I've gone bouldering. Student discount on certain days, lots of different levels for people of different experience. Bar and seating inside to hang out after your climb.

Very friendly staff and atmosphere. Quite small, but offers a reasonable selection of routes for the price. Would benefit from female route setters for a better variety of routes though.

Awesome place to go climbing. The vibe is really good and there is always someone to chat or hangout with. The climbing routes are changed frequently to bring new challenges.

Routes are renewed often, employees are always willing to give tips and tricks and are always friendly. Top location for both newbies and the more advanced climbers!

The staff is really nice. The price is 9 euros + 3 euros for renting shoes (optional). If you are a student, check on Thursdays as it is only 6 euros.
