North of Dumaguete you can find the remarkable Bais/Manjuyod Sandbar . There you can appear to walk on water. Emerging like a white oasis in the midst of blue, this strip of land provides a great spot for recreation.
But during high tide it disappears. If you plan to prolong your fun, you can stay overnight in one of several cottages on stilts that are found nearby. You can easily reach the area by boat.
