Punta Umbría stands out for its varied ecosystem formed by the Marismas del Odiel Natural Areas (one of the most outstanding wetlands in Spain), Los Enebrales (made up of pine trees and junipers as well as a rich and varied fauna), the Laguna del Portil Nature Reserve (formed by the enclosure of streams produced by the interposition of mobile dunes), and in a short time, the Dunar de la Canaleta Park. In fact, 70% of the territory of Punta Umbría is a protected area.

The Marismas del Odiel Natural Park is a Biosphere Reserve according to the classification granted by UNESCO, constituting one of the most important wetland ecosystems in Spain, serving as a habitat for important colonies of birds such as the spoonbill and the gray heron. You may go on routes organized with guides, which depart from its reception and interpretation centre.
