The Cresta del Giardino (Garden's ridge) divides the Val Scarettone from the val Mala, in the NW sector of the Grigna Meridionale.
This is the least frequented range in the whole group, quite easy to understand why
It has some, few, rock routes (100-150m) on good quality rock and some more new could be done, but the access is short only from Rifugio Rosalba and there are no paths so to get them a bushwhacking on very steep slopes is required.
