Apia sits at the mouth of which river?

Apia sits at the mouth of which river? Apia sits at the mouth of the Vaisigano River.

The river reaches the coast at Apia’s natural harbour, helping shape the city’s geography and historic importance. Apia’s built-up area occupies a narrow coastal plain, with the Vaisigano forming one of the key waterways running through the capital.

Two principal ridges extend southward on either side of the Vaisigano River. The city proper is also described in relation to the Mulivai River, which lies to the west; this can cause confusion because Apia’s broader urban area includes many villages and waterways rather than one compact municipal boundary.

The river’s low-lying valley contributes to flooding during Samoa’s wet season. Inland, Mount Vaea rises above the city, and its slopes contain the grave of Robert Louis Stevenson. The Sepik River belongs to Papua New Guinea, while the Rewa River is in Fiji, so neither is associated with Apia.
