Bernardo O'Higgins is the largest of Chile's extensive network of national parks. At 35,259 square kilometers (13,614 square miles), it's larger than the state of Maryland. (You could even throw in Delaware and still have room to spare.) Within its borders are soaring peaks—the tallest, reaching an altitude of 3,607 meters (11,834 feet), is the Lautaro volcano. At sea level, numerous fjords stretch deep into the park. The park also includes much of the Southern Patagonian Ice Field, and glaciers here come right down to the water's edge.
