Cresmina Dune
Cascais e Estoril, Portugal
The Cresmina Dune extends over 66 hectares and is a part of the Guincho-Oitavos dune system, located on the edge of the Sintra-Cascais Natural Park near Cascais in Portugal. This dune system is unusual in that, as a result of the prevailing northwest winds, the sand from the Guincho and Cresmina beaches eventually returns to the sea 5 km further to the south near Guia, after migrating over the flat, rocky and largely uninhabited area of Cabo Raso.
