Mello Blocco was held in Val di Mello. You can climb there for free, though you cannot park there without a special permit (we didn't know and got a ticket, the signs are not very obvious). The walk from town is about 20 minutes and is not too bad. You can camp in town at the Sasso Remenno Campground. It is about a five minute walk from town. A little expensive (about 15 euro per night I think) to pitch a tent, but they have really nice showers and bathrooms, and a bar and restaurant on the grounds. You can also climb at the Sasso Remenno boulders which are only a two minute walk from the campground. There is good bouldering up in the woods, and sport climbs on a huge boulder that is right on the road. You can buy the guidebook from the campground's restaurant. Oh and temperature wise...I went in August, and it was around 80 F during the day, but down into the 50s and 40s at night.
