The places for the tents are limited. The reason for this is the following. We want everybody to be happy there, so we want everybody to have their own private space: no tent right next to you!
If you come with a family, and you simply like to camp, this is the ideal place for you. Actually there is no other chace to camp here, at this wonderfull, protected piece of nature, but the festival only.
Don't forget, that camping is free!
The best choice yet is the combination of bike+tent, especially if you come from Budapest.
