Simply walk across the sand without stopping.

Avoid jumping onto the sand while having a blue suit without Gravity: the water tide makes it impossible to normalize the jump so there would be a risk of losing the blue suit and sinking into the sand. With Gravity, a full height jump makes it safe to land on the sand.
