Sant Llorenç del Munt i l'Obac Natural Park Nature · Vacarisses, Vallès Occidental, Barcelona The Parc Natural de Sant Llorenç del Munt i l'Obac brings together the massif of Sant Llorenç del Munt and the Serra de l'Obac, between the comarques of Bages, Vallès Occidental and Moianès, and extends across twelve municipalities, including Vacarisses. Its main peaks are the Montcau, at 1,056.7 metres, and la Mola, at 1,101.9 metres, where the Romanesque monastery of Sant Llorenç del Munt stands next to former lime kilns. Managed by the Diputació de Barcelona, it was declared a natural park in 1987 and enlarged in 1998 to its current 13,694 hectares, following a first zoning plan in 1972 and a special plan in 1982 that curbed urban growth in its surroundings. In August 2003 a fire seriously damaged its northeastern part. Photo: Catalaalatac (CC BY-SA 4.0) What to see and do in Vacarisses
