The Terras da Comporta Resort was developed by Vanguard Properties, the largest real estate developer in Portugal. The project comprises two plots of land, with the Dunas site occupying around 1,011 hectares of land in the Grândola municipality, around an hour south of Lisbon.

The Dunas Course was designed by David McLay-Kidd in a secluded setting on the edge of the Sado Estuary Nature Reserve. Built across 84 hectares of natural, sandy terrain, the course features vast playing areas and bold bunkering.
