Departing Puerto Natales, travel through Patagonia's vast grasslands teeming with wildlife to UNESCO-listed Torres del Paine National Park. Witness guanacos grazing freely, marvel at the thunderous Salto Grande waterfall against the Paine Massif, and admire the dazzling turquoise waters of Lake Pehoe. Continue to Lake Gray for breathtaking views of Gray Glacier's floating icebergs. After lunch, explore the Milodon Cave, where 14,000-year-old giant sloth fossils were discovered, before returning to Puerto Natales by evening.
