Also known as Mount Pioa, 523-meter-high (1,716-foot-high) Rainmaker Mountain is credited with trapping clouds, which results in Pago Pago’s receiving the highest annual rainfall of any harbor around the world. It’s possible to get a closer look at this majestic beauty with a drive up Rainmaker Pass, from which the mountain’s summit, a series of three peaks rather than just one, is visible. Known for the tropical vegetation along its slopes, it was named a National Natural Landmark in 1972.
