Southwest Alentejo and Vicentine Coast Natural Park (PNSACV) is a natural park located in southwest Portugal. It occupies an area of 895.7 sqkm (605.8 sqkm on land and 289.9 sqkm at sea) and is one of the last strongholds of the wild European coast. It has one of the highest levels of biodiversity in the country with over 12 endemic species of plant and several bird nesting sites. The park was created on 7 July 1988 in order to promote the protection and sustainable use of natural resources and other natural, landscape and cultural values while promoting the economic, social and cultural development of the region.

The Rota Vicentina is a network of hiking and cycling trails that crosses the Southwest Alentejo and Vicentine Coast Natural Park. Two hiking routes of the Rota Vicentina are especially popular:
