South of the border, luxury isn’t relegated to just the resorts. At the new Camp Cecil, on the UNESCO-protected island of Espíritu Santo in Baja, white canvas tents with cushy beds, teak lanterns, and rattan sofas in the sand are the kind of hideaway you could get used to. Naturalist guides take you kayaking around bird colonies, SUPing over translucent waves, bouldering up sculpted arroyos, and swimming with sea lion pups. Ivan, the camp’s Italian chef, lays out three miraculously fresh meals a day, plus happy hour. From $275.
