There are daily flights, weather permitting, from Santiago to Balmaceda. From there, it’s an eighthour drive to Patagonia Park via the lakeside town of Puerto Río Tranquilo. Where to Stay In the heart of Patagonia Park, the Lodge at Valle Chacabuco is built from locally quarried stone with rustic ceiling beams and floors of recycled and refurbished wood. Decor is safari-chic—think black-and-white wildlife photography, leather armchairs, and handhewn furniture. The central lounge area, with an open fireplace and views of Mount Tamanguito, is the perfect perch to enjoy a Patagonian beer or wine after a hike through the fields ( open from October 1–April 30; patagoniapark.org; doubles from US$400).
