Start your two and a half-hour Bora Bora snorkeling tour in the afternoon, boarding a motorboat that will take you across the lagoon. Make multiple snorkeling stops along the way for close-up looks at sharks, rays and other marine life. Stop near the barrier reef and discover a coral garden teeming with nearly 700 species of tropical fish. Black-tip reef sharks are a highlight of Bora Bora. Continue your excursion where you'll have the chance to spot sea turtles, dolphins, whales, leopard rays, and manta rays, depending on the weather conditions and time of year
