3 curated Swimming spots in Samoa, each with its own note and source.
Upolu Hochland
A crater lake at 760 m in the highlands of Upolu, about 400 m long and up to 17 m deep. Reaching the shore is a roughly two-hour return hike over muddy stretches and climbs; a local guide is advised because the path is hard to find. Feral goldfish live in the water.
