Les Guilleries is a mountain range located in the comarcas of Osona and La Selva in Catalonia, nestled between the Plains of Vic (Plana de Vic) to the west, the Anglès municipality to the east, the northern shores of the water reservoirs Sau and Susqueda to the north, and the municipality of Sant Hilari Sacalm to the south. The latter is considered an unofficial capital of Les Guilleries as it’s a major town and even boasts a specialized local history museum.
The tallest point of Les Guilleries is Sant Miquel de Solterra whose peak towers 1204 metres above the sea. Hiking to the top will reward you with the ruins of the Solterra castle and the Saint Michael chapel.
