Seclusion factor: You reach the resort via a 30-minute taxi ride from Puerto Vallarta to Boca de Tomatlán, a 30-minute boat ride, and a walk through a village and up a path to a seaside cliff. No worries―a mule will haul your luggage.
What makes it special: Ask the kitchen to pack a picnic for a day trip to the deserted Marietas Islands. The nature preserve is home to whales and rare birds like the blue-footed booby.
Cost: from $175 per night, plus $95 daily per person for meals;
