The diversity of its nature is certainly one of the great strengths of the Algarve. It is so easy to move between differing environments, each with a range of nuances on a similar theme of natural beauty. From the coast up to the hills, there is a wide range of landscapes to explore, each of them special in their own way. The coastline is home to an ecological system of amazing biodiversity - from the indigenous birds with their imposing nests through to the molluscs and crustaceans that have long supplied the regional shellfish sector - perfect for some close-up observation over the course of a long stroll.
