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