EcoCamp offers a string of geodesic domes in the far jagged tip of the Torres del Paine National Park. Each has snug beds layered with sheepskin throws, quilted walls to guard against the elements and skylights overhead for stargazing. All except the standard domes have private bathrooms – and some even have heaters, wood-burning stoves, sofas and verandas. Activities range from guided treks and wildlife excursions to mountain biking through the wild Patagonian plains.

Los Notros Argentina
The frozen wall of the Perito Moreno Glacier forms the backdrop to Los Notros. This rigid river of ice – which ruptures and refreezes – can be climbed on foot, scaled with crampons or seen by cruising the Brazo Rico waterway, past icebergs that have flaked off over time. If all that sounds too taxing, admire it from the comfort of one of 32 guestrooms at the lodge. Sybarites can indulge in gourmet food at the restaurant, which serves duck, trout and terrines with 150 Argentinian wines.

Poised over the precipice of the Salto Chico waterfall, explora flaunts 49 rooms within a landmark building by architect José Cruz Ovalle.
