At the end of 11 miles of bad road that peters out at Kaulana Bay, in the lee of a jagged, black-lava point, is Ka Lae (“The Point”)—the tail end of the United States, often called South Point. From the tip, the nearest continental landfall is Antarctica, 7,500 miles away. It’s a rugged 2-mile hike down a cliff from Ka Lae to the anomaly known as Papakolea (Green Sand) Beach. In May, the 10-day Kau Coffee Festival (www.kaucoffeefestival.com) in Pahala includes hikes, music, hula, and farm tours.
