To Sua Ocean Trench, Lotofaga

WOOOOW!!!! Me and my wife Annika had a wonderful stay in Samoa including the visit to the To Sua Ocean Trench. It's a "must see" if you visit Samoa. ToSua is a beutiful place just next to the ocean. The trench itself is amazing with the ladder, platform and sand bottom. It has a direct connection to the ocean so the water is nice and fresh but still calm due to the underground tunnel. Bring swiming gear and you can dive trough the tunnel out in the sea. Leif Törngren / Sweden

This majestic swimming hole on Samoa's Upolu Island sits just inland from the Pacific coast. It was formed when the roof of an ancient lava tube collapsed, exposing the 98-foot-deep teal-blue pool. This is the largest of many such tide pools and blow holes formed in the area many thousands of years ago. An underground cave system connects this swimming hole to the nearby ocean, and the water rises and falls with the tides. 'To Sua' translates to English as 'big hole.' While accurate, it feels like an understatement in this context. For adventurous visitors to Upolu Island, To Sua Ocean Trench can feel like a trip to another world. To get to this natural saltwater pool, make your way along a cliffside path surrounded by lush forest. Then climb down to the waters via the wooden ladder. After your swim, you can squeeze through a cave-like lava tube to find yourself on a short, sandy beach.
