Hello Fernando...first question, will you have a car? The nearest area is Kochel (limestone) but I donยดt know much about it since I havenยดt bouldered there myself. Boulderrausch.de however has directions, Kochel is also in 8a.nuยดs database. Kochel is also reachable by public transport but that can be a little bit tedious.
