The former owner of North Face, Doug Tomkins, has created a 30,000 acre wildlife refuge and eco-retreat in Argentina's Corrientes province. The Conservation Land Trust has attracted a slew of nature lovers in pursuit of discovering the beauty of Argentina's vast northeast. The place to stay? Estancia Rincon del Socorro is a 12,000-hectare former cattle ranch on the edge of the Ibera wetlands that is now a nature reserve. Doug and his wife Kris restored a beautiful property, originally built in 1896, including three bungalows and the main house, El Casco, which offers spacious rooms with high ceilings, a screened verandah, well-stocked library, and terraced dining area where beautiful organic meals are served, with fruit and vegetables plucked from the kitchen garden and delicious Argentine barbecue (free range meats). Relax by the pool or take to the savannah on horseback, riding with a gaucho on one of the native horses.
