Tropicana on the West Coast is another popular spot. This is a quite beach but is popular with surfers when there are waves, a beautiful beach with turquoise waters and perfect for a late afternoon walk.
If you're surfing just be wary the waters here are shallow and at low tide you've got coral right underneath your feet. If there's a cool break and you enjoy a drink then the best way to see all the West Coast is to go on a catamaran trip.
