Designed by American Arthur Hills, Oitavos Dunes is a beautiful golf course routed through the sandy, tree-lined site that feels more links than parkland. The balancing act is certainly an achievement in itself, and golfers who visit Oitavos Dunes will notice the spectacular change in biomes, which clearly have this as the créme de la créme of the country. Interestingly, Oitavos Dunes was the first golf course to receive Audubon Gold Certification, which acknowledges and celebrates its relationship with nature and local animals.
