UltraAnt Climbing Club

Old school cool underground-y boulder gym in the basement of an old town city building.No modern hi-tech to be seen but that is not a bad thing in this case. Gives a very different vibe and experience, compared to many other, very modern and spotless gyms.Boulders are plenty and very creatively built, including building elements like arches and a doorway.The atmosphere was very friendly and welcoming.Has walls with adjustable overhang, rental shoes and showers.Two bits of advice:1) The entrance is shared with the building above and the gym has no doorbell at the main entrance. From the street, enter the main door - it should be unlocked and open. Head inside, then right, then follow the signage downstairs. Doorbell is in the basement.2) Payment is cash only and the payment model was a bit confusing for me and my companion due to an obligatory one-time payment for a member card on top of the entry fee. I recommend talking to the extremely friendly and helpful staff to figure out what exactly you need to pay.An ATM is a short walk from the gym.Will definitely come back and would recommend!

Only for advance climbers, cant recommend for beginners. But if you are in town and love climbing pay them a visit!

There is a wide variety of problems, but it is the smallest climbing gym I've EVER seen. The climbing area is the size of the locker room at most other gyms.

Super surprised when I went to this gym! Very very good location and super friendly staff!I'm not the strongest climber so couldn't do any of the hardest boulders but, everything up to the second hardest grade was really well set! Fun movement and nice holds!I do recommend this for some fun climbing!

Great little gym! I only had a little time in town but needed to log some climbing time after all the pilsner I've been swilling: this place was perfect. Reasonably priced, friendly staff, lockers, and a bar so that after a quick workout I could get right back to beer drinking. A nice respite from the throngs of tourists. Mostly bouldering with a few lead climbs. I found a good variety of routes and some interesting, not always obvious, route setting. I'd happily recommend this spot to anybody looking to pull on some plastic while in Prague.

Super small and old boulder hall. It's very different from other ones because you don't follow the routes by the colours but by some stickers attached to them that you can't really see while you're climbing. It's very confusing. Would go there again.

Great gym, located in the city center, right next to old town. Mostly bouldering but you can do some lead climbing (you can actually climb across the roof if you are tough enough!) Though one of the smaller gyms in the city, they have walls that can change angle degrees, making the same problem quite different, also a little dining area for after a session with beer on tap, always a plus.

A great little wall. A bit dated but i was looking for a few hours to keep my eye in and this place was exactly what I needed. The yellow trousered woman that helped me was pleasant and gave me assistance when needed. The routes follow an older way of setting so it can be a bit confusing as you don't follow colours as much as stickers across a wall. Makes onsighting a bit more difficult. But that is only a minor issue. Spent 3 hrs and didn't run out of things to climb. Good afternoon had!. And its cheap!!! What more does a climber need?

A cosy old-school style boulder gym is somehow refreshing amongst the others, huge modern boulder gyms. Thereto, it’s placed in the very heart of Prague. Friendly staff included. One could not wish more.

Excelent price/quality/location Bouldering GYM.Personally I found the level of the routes quite challenging in general, which it's also something that varies from country to country, but with the number of professional climbers in Czech Republic you can't expect any less!I have to add the hospitality from the owner was incomparable to me, he is a really nice person, Greetings from this Chilean climber :)
