Main Beach Sand Dunes
These sand dunes are taken close to the Sheraton Mirage, about 1 kilometre up from the main beach of Main Beach. If you want to get away from the crowds, but still be near a lifeguard and amenities this is the perfect spot. Wander another minute or so in either direction and you'll have the sand dunes to yourself (but avoid this area late at night for that same reason).
