3. Samoa’s To Sua Ocean Trench
This interesting naturally formed shape in the middle of the Lotofaga village is offering a very distinctive experience with its beauty. The name sua means “big hole” in their language, and well it is a big hole in the middle of the land, where you can swim in almost around 100-foot-deep waters. With its pristine look, it has lots to offer to visitors, one of the bucket list locations that you may want to add to your list.
