No glass windows separate guests from the elements at this zen, innovative, eco-lodge. Designed by award-winning architect John Hix entirely of poured concrete, mosquito netting and retractable doors are used in the rooms when the elements get fierce. But that’s a rare occurrence, and most find staying here, using the private outdoor showers, sitting on their terraces and communing with nature to be a remarkably serene experience. In fact, that’s just about all you can do at Hix Island House: The remote, 12-acre complex has a swimming pool and a daily yoga class, and that’s it. Guests are provided with food and a kitchen, but must travel if they want entertainment or a restaurant meal. Still, those who stay here often find it a tremendously joyous, rejuvenating experience. Book early, as Hix House gets many repeat guests.
