To Sua Ocean Trench, Lotofaga

Marvel at the splendor of To Sua Ocean Trench, a massive swimming hole filled with blue water and surrounded by lush vegetation. The swimming hole is set deep in the ground, so a ladder is required to enter and exit. The water fills the hole via an ancient lava tube connected to the ocean, which creates a current. Weak swimmers can take hold of a rope across the center of the hole. Bring something to cover up with when you're not swimming, as conservative dress is requested out of the water. A few picnic tables are available, so consider packing some refreshments.

  • This is such a beautiful spot with a lovely view of the ocean all around. Really scary getting up and down the ladder and the current was quite strong but there was a rope to hang on to. My 7 year old...  more »

  • Soothing place to go for views and a nice swim. The ladder down does require a level of fitness, nothing extreme. The photos from others are not deceiving, it really is clean and blue. Note: ‘Revealing’ swimwear can only be visible inside the trench. There are ropes to help you move around in the trench as there is some current. The rope going North (into the cave) has a nice view when you look up. While at the trench, head South of the trench to see the ocean ‘mouth’. Food and water is also available.
  • This place is amazing. It is set in some beautiful gardens at the south east end of Upolu. A lava flow has left a couple of big holes in the land and the sea has got into the one nearest the coast, creating a big pool at the bottom of a hole, with big cliffs all around it. Access to the pool is by a steep path and then a long wooden ladder, it's not for the faint-hearted. The pool itself was at least 1.5m deep in most places, you need to be a capable swimmer as there are no real edges or beaches and the tide flows in and out.
