Rainmaker Mountain — also known as Mount Pioa or Mount Peiva — rises behind the bay and is one of the most recognisable landmarks on Tutuila. It catches moisture-laden trade winds and creates its own micro-climate: the summit is almost perpetually in cloud, which is why this part of the south coast receives some of the highest rainfall in American Samoa. The dense rainforest on its flanks is part of the National Park of American Samoa.
The mountain is best appreciated from the water or from the beach, where the whole massif frames the eastern end of the bay. There is no maintained trail to the summit; the national park section nearby has walking tracks through the same forest type.
story: "Somerset Maugham based the character Sadie Thompson in his 1921 story Rain on a woman he met in Pago Pago while waiting for a ship during heavy downpours. The relentless rain he described was almost certainly driven off Rainmaker Mountain, which intercepts clouds year-round."
