To-Sua Ocean Trench — “To-Sua” translated means “giant swimming hole” —is a 98-foot deep natural pool located on the southeast coast of Upolu Island. Surrounded by lush greenery and tropical gardens, this rare natural wonder was hidden for decades and sits directly in the middle of a volcano. It was only discovered thanks to the owners who found it while developing the land around it.

Visitors can go scuba diving in the cave as well, though it's only recommended for skilled divers. Mark Kolbe Others can reach the pool by a ladder and relax the day away in its crystal clear waters.
