This is our favorite fantasy, and we bet you've had it a time or two as well: You're walking through a forest, ducking under vines and minding the tree roots, when suddenly you emerge out into the sunlight on the edge of a perfect beach with soft, fine sand that gently descends into clear waters. You look left and right, and there's not a soul in sight. Sigh. Places like this do exist, and we've found them for you: Some require a bit of a trek, others are like natural swimming pools, and at one the sand is likely mixed with Minoan archaeological ruins. So get out there, have a local draw you a map, and be one of the few whose daydreams are fulfilled.
