Dive into one of Samoa’s most breathtaking natural wonders at the To Sua Ocean Trench. This 30-metre-deep turquoise swimming hole, surrounded by lush greenery, is a must-visit on Upolu’s south coast. A wooden ladder leads you down into the crystal-clear water, where ropes help you navigate any gentle currents. Explore the surrounding gardens, peer into other sinkholes, and follow a coastal path to a traditional Samoan swimming pool for even more relaxation.
