Snorkelling is a daily fixture on this voyage through the British Virgin Islands. Not only will you explore the high-visibility reefs of Sandy Cay and Peter Island, you’ll also head to Virgin Gorda to swim through the Baths, a forest of granite boulders that is flooded with seawater. Other highlights include hiking the birdwatching trail on Sandy Cay, a visit to the pink flamingos of Anegada and swimming with sea turtles off Guana Island, where you may also glimpse leaping dolphins.
Rising out of a blue lagoon, the volcanic island of Bora Bora is the focal point of this South Pacific sailing holiday. Explore coral gardens on a traditional Polynesian canoe before diving beneath the water to swim with barracudas, eagle rays and blacktip reef sharks (if you’re lucky) in the barrier reef. You can also enjoy snorkelling off the white beaches of Huahine – home to the sacred blue-eyed eel – and Raiatea, where you’ll have the option of touring a black pearl farm.
Head to the Grenadines for some of the best snorkelling in the Caribbean. This trip will take you to the calm, teal waters of Bequia, the archipelago’s northernmost island, before you swim with sea turtles in the Tobago Cays, an uninhabited atoll within a protected marine park, surrounded by a barrier reef. You’ll also need your swimwear for a dip in the natural pool underneath Saint Vincent’s Dark View Falls, and to soak in the hot springs around the Soufriere volcano in Saint Lucia.
Snorkelling dominates this Seychelles adventure, which kicks off with a visit to the Sainte Anne Marine Park, established in 1973 as the first of its kind in the Indian Ocean. While swimming over seagrass meadows and coral gardens, you’ll hopefully meet hawksbill turtles, manta and eagle rays and, if luck is on your side, bottlenose dolphins. Further opportunities for snorkelling arise off the white beaches of Grande Soeur and in the luminous waters around St Pierre, a 5sqkm (2sqmi) islet off Praslin.
Encounter technicolour tropical fish in two unforgettable settings on this sailing trip around the Bahamas. First up is Thunderball Grotto on Staniel Cay, a series of underwater caves named after the James Bond film in which they appeared, and inhabited by shimmering shoals of angelfish and yellowtail snappers. Next up is Norman’s Cay, where you’ll snorkel the coral-covered wreck of a plane that crashed in the 1970s on an ill-fated mission for Pablo Escobar’s Medellín cartel.
