The first time I visited Sandbanks Park, I missed Dunes Beach. I only saw signs for Outlet Beach and did not know there were three beaches to explore. Dunes Beach, obviously the one the closest to the dunes, is definitely unique. You must get closer to better gauge the size of this natural playground. My kids turned into desert survivors in a flash (once they'd hiked the highest peek). Then, they slid down the silky slope all the way to the water. The shallow water in the bay is the calmest of the Sandbanks, and the warmest. Perfect for younger kids. Outlet Beach's water is also shallow and great to built sand castles. It stretches along 3 kilometres, 30 metres wide in some places. It includes a designated pet area where it meets the River Outlet. Sandbanks Beach's narrow strip of sand runs along 8 kilometres. It is the best place for beach walkers. The water is a bit deeper and the nice waves that usually form when it is more windy adds to the pleasure for young swimmers.
