Rural municipality formed by several masies (traditional Catalan farm buildings) and a tiny village in the northwest sector of the Massif of Montseny. It is a place for rambling and to get to the Matagalls' Peak and to the plain called Pla de la Calma through Collformic, at an altitude of 1145 metres.

It is a place almost hidden, of a moderate climate, so that second houses were built around. Because of the great variety of altitudes and its complicated orographic system, we find a great diversity of climates and vegetations.

The historical centre is the Sant Martí del Brull's Church, situated at the foot of the remains of the Brull's Castle. We also have to stand out the great masies (traditional Catalan farm buildings) as Casademunt and the prehistorical site of Montgròs. All this variety gives the village cultural and landscape diversity, where the visitor can follow infinite nature routes that go into the Natural Park of Montseny.
