The Montgrí mountain range, with calcareous rock, has a total protected surface area of 3,768.10 hectares under the PEIN. Aside from its natural beauty, it is also outstanding for the rich historical and cultural heritage it retains, such as Montgrí castle, the prehistoric caves and Santa Caterina church.
The Montgrí range has good signposting for hiking and for bicycle excursions.
Visitors can likewise engage in interesting activities: guided and thematic visits, excursions, reconstruction work, bird watching, reforestation, work camps, cabin rebuilding, etc. Companies in the zone also organise other sport- and adventure-related activities and activities based on various themes.

Flora: This is a highly deforested zone, mainly taken over by pine groves reaching down to the sea, and thickets of rockrose and holm oak. Interspersed among the sectors with vegetation are primarily rocky zones forming ravines, caves and crags.
Pine, the predominant tree, is nevertheless to be found alongside kermes oak, furze, white rockrose, black rockrose and rosemary. In the maritime zone the rocky settings form bays backed by steep but very beautiful cliffs, such as Cala Pedrosa or Cala Ferriola.

Fauna: In terms of fauna, we might highlight the presence of many birds of prey, such as the Bonelli’s eagle, the peregrine falcon, Montagu’s harrier, the falcon, the short-toed eagle, the sparrow hawk and the goshawk. Other characteristic birds are those typical of rocky environments, such as the blue rock thrush and the rock sparrow. In the holm oak and bramble zones there are various species of small birds, while in the woodland habitat there are blue titmouse, woodpigeons, crossbills, etc. Finally, in the clearings, we can observe crested larks and partridges.
The seacoast is inhabited by species similar to those which live on the nearby Medes Islands: with algae formations, various sea birds and fish typical of the rocky-bottomed waters, as well as algae colonies.
