14 Bluest Waters in the Whole Wide World
To Sua Ocean Trench, Samoa
Known colloquially as “The Big Hole,” this local swimming spot in the South Pacific is a natural wonder. To enjoy the translucent teal water, visitors must hike through a lush forest in the lava fields outside of Lotofaga village on Upolu Island in Samoa. From there it’s a long climb down a steep ladder—or for the bravest, a quick jump—into the hole that is almost 100-feet deep. The water comes in from lava tubes that connect to the ocean, making sure that this downright gorgeous swimming hole never dries out.
