Nature's diversity is one of the Algarve's greatest treasures.

From the coast to the Algarve hills, there is a whole diversity to be explored in the most varied ways. In the coastal area, an extremely diversified ecological system invites you to take a longer and closer look during pleasant walks along the countless trails and routes existing along the entire coastline.

Far from the extensive beaches of fine, golden sand, the green and brown tones mix with the vibrant colours of the orchards with the most varied typical fruits of the region. In the more inland parts of the region, there are also countless routes worth exploring. Both the mountain and valley landscapes and the geological features of the region are something to be enjoyed while enjoying the calm, the sound of birds and the pure air of the Algarve hills.

• Ria Formosa Natural Park - This is the largest wetland area in southern Portugal and covers an area of around 18,400 hectares. It is a spectacular barrier-island system almost 60 km long made up of 2 peninsulas and 5 barrier islands. It is one of the most precious treasures of the Algarve's ecosystem full of undiscovered wildlife. The area is particularly important for birdlife, especially waterfowl. The dunes and saltpans have rich and unique vegetation, especially characteristic of this type of environment. 

• Vilamoura Environmental Park - Located in the municipality of Loulé, near Vilamoura Marina, this park is in part of the old Quarteira Estate where several species of birds nest. It is a protected area, classified as an Agricultural Reserve, with orchards and horticultural, cereal and pasture crops. In the 1970s, after the agricultural fields were abandoned an extensive reed bed was formed, and two artificial lakes were later built - important for local vertebrate species.

• Ria de Alvor - indicated as the third most important wetland in the whole of the Algarve and the first in the Western Algarve. It combines factors such as tidal action, climate, soil type and topography, and has a wide diversity of habitats that support large biodiversity. The habitats that exist in the Ria de Alvor are the result of the Mediterranean climate with mild, wet winters and hot, dry summers, and the geographical and geological characteristics of this location, which contribute to a wide variety of habitats.
