Whether you’re skimming Pago Pago Harbor in an outrigger canoe or casting a line for hefty tuna and marlin, there are endless ways to explore the sea here. To find the treasures hidden in the dense forest canopy, head to the National Park of American Samoa for a trek through fruit bat country. The Samoan fruit bat has a wingspan of up to three feet, and the fuzzy mammals can be spotted dangling from trees or swooping through the air in search of fresh fruit and nectar.
