Isla Blanca is in fact a narrow peninsula some 30 minutes north of Cancún, with the lagoon to the west and the Caribbean to the east. Seemingly no one except the locals come to this untouched, isolated beach, dotted with tiny seafood restaurants, the occasional vacation cabin, intermittent lounge-chair rentals, and a growing camp of kite surfers. You’ll need to arrive by car via coastal highway that quickly turns to rough dirt path, but the experience transcends the rusticity once you hit the Caribbean’s pristine white sands and cool turquoise surf; the lagoon’s shallow, brackish waters, just steps from the ocean, provide ideal fly-fishing and kite-surfing conditions.
