Pumalín Douglas Tompkins National Park (Spanish: Parque nacional Pumalín Douglas Tompkins) is a 400,000-hectare (1,000,000-acre) national park in the Palena Province of Chile, created by Tompkins Conservation, which was endowed and led by the American business magnate Doug Tompkins and his wife, former CEO of Patagonia, Inc., Kris Tompkins. Designated a Nature Sanctuary in 2005, Parque Pumalín was Chile's largest private nature reserve and operated as a public-access park, with an extensive infrastructure of trails, campgrounds, and visitor centers. By an accord announced on 18 March 2017, the park was gifted to the Chilean state and became South America's largest national park.
