About Margaret River

Margaret River town sits between vineyards and the Indian Ocean, with world-class surf at Prevelly, Yallingup and Gracetown along the coast. The region's wineries and breweries fill the hinterland, and the caves at Mammoth and Lake offer stalactites and fossils underground. December to March is the dry, warm season; surf is best in the shoulder months, and winter brings storms and green hills.
