To Sua Ocean Trench is a natural swimming hole located in Lotofaga village, on the south coast of Upolu island in Samoa. The name "To Sua" means "big hole" in Samoan, and it is one of the most popular tourist attractions in Samoa.
The Afu Aau Waterfall, also known as Olemoe Falls, is a spectacular waterfall in south-eastern Savai'i that plunges from the rainforest deep into a fresh-water swimming pool. The pool is very deep but it gets very shallow towards the outer rim. The fall eventually flows into three other smaller separate falls offering a truly enchanting experience for visitors.
