Great Barrier Reef (Australia)

This 1,429-mile ecosystem is the largest living thing on earth. To put things in perspective, the Great Barrier Reef is so huge, it’s visible from outer space. It also boasts 600 types of hard and soft coral plus numerous species of fish, mollusks, dolphins, sharks and turtles.

Go to this Indonesian national park for the Komodo dragons (it’s one of only five places in the world where you can see these fantastical lizards in the wild), stay for the awe-inspiring snorkeling. Beneath the waves, you’ll witness an array of exotic creatures.

Galapagos Islands (Ecuador)

The volcanic archipelago is famed for its diverse wildlife, both on land and in the sea—remember all that stuff about Darwin’s finches? That was here. Visitors can encounter a mesmerizing array of marine inhabitants—sea lions, turtles, dolphins, orcas and humpback whales.

Kealakekua Bay (Hawaii)

Hawaii isn’t lacking in snorkeling sites, but Kealakekua Bay stands out with its history and hypnotic inhabitants. For prime marine-life peeping, head to the protected waters in front of Captain James Cook Monument, an obelisk dedicated to the British circumnavigator.

Ambergris Caye (Belize)

The crown jewel of Belize has a lot going for it, from sandy beaches to top-notch snorkeling. Off the eastern shore is the second largest barrier reef in the world, which provides endless opportunities for aquatic adventure—whether you want to stay close to the coast or venture out further.

Silver Bank (Dominican Republic)

Ever dreamed of snorkeling alongside humpback whales? Visit this bucket-list destination between December and April, when these magnificent marine mammals migrate to the warm, shallow waters of Silver Bank to mate and breed.

The Baths (British Virgin Islands)

Situated on the southwestern tip of Virgin Gorda, The Baths is the most picturesque attraction on the island. Huge granite boulders (some 40 feet in diameter!) form sheltered tidal pools, grottoes and tunnels where the sea meets the sand.

The Maldives

The ultimate honeymoon destination, the Maldives promises sun, fun and sophistication. Oh, and did we mention there’s awesome snorkeling? In addition to posh resorts and private beaches, there’s a slew of underwater wonders—from anemonefish and giant clams to octopus and critically endangered hawksbill turtles.

Uepi Island (Solomon Islands)

Bordered by Marovo Lagoon on one side and the Pacific Ocean on the other, Uepi Island is known for its oh-so-Instagrammable scenery. You don’t have to venture far from the white sand beach to peep protected reefs teeming with eagle rays, barracuda and batfish.
