The Montgrí massif is the great limestone formation that forms the natural border between the Baix and Alt Empordà.

It has an area of ​​2,300 hectares and is made up of three mountains, all slightly higher than three hundred meters in height: the mountain of Ullà (or Mount Anill), the mountain of Montgrí and Montplà, in addition to several lower elevations that give it continuity for about eight kilometers in length to the coast of L’Estartit, where the Maura rock and the Moratxa tower stand out.

The landscape value of this area is characterized mainly by its great heterogeneity, by its uniqueness and by the set of geological, meteorological and human factors, which have shaped its physical and natural environment with characteristic plant and animal communities.

With regard to fauna, it is worth noting the presence of a large number of birds of prey, such as the Bonelli’s eagle, the kestrel, the short-toed eagle or the hawk. Other characteristic birds are those typical of rocky environments, such as the solitary rocker or the screech sparrow. In areas of holm oaks and undergrowth, different species of small birds stand out, and in forest habitats, blue tit, wood pigeons, crossbills, etc. Finally, in the open areas we can observe limps and partridges.

It is a highly deforested area, occupied mainly by pine forests that reach the sea, with holm oaks. Between the vegetation sectors there are eminently rocky areas that form crags, caves and cliffs.
The pine, which is the predominant tree, coexists with kermes oak, gorse, white jaguars, black jaguars and rosemary.
In the maritime zone, the rocky environments form very steep coves but of great beauty, such as Cala Pedrosa or Cala Ferriola.

Ponç Hug, Count of Empúries, altered the course of the Ter around 1302 and the dry course of the river no longer represented a barrier to the spread of the sands deposited by the Muga, the Fluvià and the Ter itself.
Transported and piled up by the north wind, some large mobile dunes advanced until the end of the 19th century, causing problems for agriculture and the population. Some dunes that advanced an average of 16 meters / year.
From 1895 a long work of forestry engineering began and this dune was fixed by repopulating all these dunes with plant species, making screens against the wind and also planting species in perpendicular lines.
Plant species such as borró (Amohila arenaria), white pine (Pinus halepensis), stone pine (P. pinea), pinastro pine (P. pinaster), cypress (Cupressus sempervirens) and drought-resistant shrubs such as mastic (Pistacia lentiscus ) or broom (Spartium junceum).
