Visitors can rent or bring their own snorkel gear and step into an undersea world of coral and fish. The 650-foot underwater trail (maintained by the National Park Service) features plaques that provide a wealth of information about the sea life beneath the water’s surface.
Keep an eye out for colorful Angel Fish, Parrott Fish, Sergeant Majors, Yellow Tail Snapper and Puffer Fish, which swells up when it’s threatened. Also watch for sea turtles that swim effortlessly then pop up their heads for air from time to time.
Among the coral in Trunk Bay, one can see: Brain Coral, with folds and grooves that look remarkably like a brain; Fan Coral is wide, thin and rounded and sways back and forth to the rhythm of the tides; Finger Coral has large pores, grows in thick colonies, and its branches have swollen tips.
