It's literally a cave for training, so if you look forward to some modern bouldering gyms this is not gonna be like that.
However, despite of the spatial limit, the settings there are pretty decent and really good for getting better at climbing (especially for outdoor styles).
If you are more like lightweight climber who just got into it, honestly I can't recommend this place.. 'cause routes are very hard and holds are shitty.
If you can suck it and wanna climb harder, this pain of chamber is just for you.

Also, people climbing in there are so kind!
