Fodor's Expert Review To Sua Ocean Trench

Samoa has no shortage of waterfalls, natural-rock swimming holes, and coastal blowholes. To Sua, which means "big hole," is one of the most impressive natural sights on the main island of Upolu. It's a crystal clear, turquoise-blue 30-meter (100-foot) hole, accessed by a very steep wooden ladder, which some people might find vertigo-inducing. The ladder leads down to a small wooden platform from which swimmers jump or dive. Those who don't want to venture into the trench can take photos, as it's a great sight, and nearby are gardens, a blowhole, and a small beach. It's near Lotogaga village on the south coast of the island—a small, faded sign marks the spot (look out for it, as it's not easy to see).
