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.
