Points of interest

Sant Llorenç del Munt i L’Obac Natural Park, the first Natural Park to be declared in Spain, is a largely rocky mountain massif in central Catalonia close to Barcelona. The highest summit (where the Romanesque Monastery of Sant Llorenç del Munt is located) is called la Mola at 1,104 metres. Montcau 1,056 metres is another important peak of the massif.

Rugged and rocky, the unique landscape of the area is due to the constant erosion that the rocks are subjected to, resulting in cliffs and monoliths of red conglomerates of outstanding beauty.

This area is also included in UNESCO’s Global Geoparks register.

The base of the massif is occupied by pine forests (Pinus halepensis, Pinus sylvestris, Pinus nigra) and in many areas they mixed with holm oaks (Quercus ilex) and Mediterranean shrubs such as heather (Erica sp) and strawberry tree (Arbutus unedo).

Holm oaks are the most characteristic and extensive forest with undergrowth species such as rowan (Sorbus), box (Buxus) and kermes oak (Quercus coccifera). Hazelnut groves (Corylus avellana) can be found in the shadiest valleys.

In the rocks and on the cliffs there are plants of great interest, adapted to extreme conditions. Typical of places with little soil and facing north are Pyrenean-violet (Ramonda myconi), the endemic limestone saxifrage (Saxifraga callosa ssp. Catalaunica ), the polypody fern (Polypodium vulgare ), aromatic thyme (Thymus vulgaris), wolf’s eye (Onosma tricerosperma), St Bernard’s lily (Anthericum liliago ), wild tulip (Tulipa sylvestris ssp. Australis) and narcissus (Narcissus dubius and Narcissus assoanus).
