Daily travel in the lesser-known island nations of the Pacific, exploring the world's best natural swimming pools

It's only a half-hour flight from Pago Pago in American Samoa to Apia, the capital of Samoa, although they are the same ethnicity, they are divided in two. The scenery here is not much different from that of American Samoa, typical tropical island views, nothing more than the sea and the beach. I tried staying in a local earth house for one night, with a tin roof and mats made of grass on the side for some shade, which was somewhat uncomfortable. In the room, you can see geckos and even snails, and with the recent rainy season, it's a bit overwhelming, especially since these houses are not cheap. Besides the sea, the forests of Samoa also have some nice attractions, such as the To Sua Ocean Trench on Upolu Island, which is known as the world's best natural swimming pool. The nearly 30-meter-deep sinkhole is surrounded by pure natural greenery, with only a set of wooden stairs extending downward and a diving board, almost no embellishments. The water in the trench is seawater, connected to the ocean through a deep channel, but unfortunately, it was a rainy day when I visited, and I did not capture the most beautiful moment. The Sheraton must be the only international chain hotel in this country, and although the Sheraton here is a bit simple, it's still better than staying in a grass hut. Traveling around, I found that public transportation in this country is particularly inconvenient. The most convenient way to get around here is to hire a car, which costs about 200 Tala, or roughly 500 RMB per day, which is quite expensive.
