For those seeking adventure and solitude, Aganoa Beach is a hidden gem on Upolu’s south coast. This secluded, crescent-shaped black-sand beach is accessed via a rough 3 km dirt track through the forest—perfect for spotting kingfisher birds along the way. With no facilities and often few visitors, Aganoa offers a raw and untouched coastal experience. While the deep waters and occasional strong currents require caution, the beach is a prime surf spot between April and September.
