To Sua Ocean Trench: Samoa's Iconic Swimming Hole on Upolu
Discover the stunning To Sua Ocean Trench, a unique sea-filled swimming hole on Upolu's south coast, and why it's a must-visit in Samoa.
“On the south coast of Upolu in Samoa, To Sua Ocean Trench near Lotofaga turns a flat grassy plateau into a sudden drop of lava rock and clear sea water, a striking natural basin set a short distance from the shore.”
An article from AD HOC NEWS highlights the incredible natural wonder that is the To Sua Ocean Trench, calling it a place "where Lotofaga’s lawn drops into the sea". This description perfectly captures the essence of this unique spot on the south coast of Upolu, near the village of Lotofaga.
The article explains that "To Sua" translates to "big hole," a fitting name for this deep, sea-filled trench formed within a lava field. It's a remarkable geological feature, with clear seawater at the bottom connected to the Pacific Ocean through underwater passages. This means the water in the trench gently rises and falls with the ocean tides, creating a truly dynamic swimming experience.
Visitors descend a sturdy wooden ladder to a platform, from which they can enter the inviting waters of the trench. The surrounding volcanic rock walls, adorned with hanging vegetation, create a secluded and beautiful environment. The local community has also done a wonderful job maintaining the area above, with lawns and paths giving it the feel of a well-tended garden perched over this dramatic natural basin. It's a truly unforgettable place to visit and swim in Samoa.
