Nothing else in Mexico looks quite like Balandra, a vast shallow lagoon on the Sea of Cortez where pale jade water sits warm and waist deep across an enormous flat backed by desert hills. It is protected, so visitor numbers are capped and the calm is real, and at low tide you can almost walk across the bay. It takes the top spot because the water quality and the sheer strangeness of the colour are unmatched, and the sargassum that troubles the Caribbean never reaches here.
