Day Trip to Rosario Islands from Cartagena
Only an hour by boat from Cartagena, the Rosario Islands are home to the only underwater national park in Colombia. We snorkeled for 45 minutes with a guide and spotted wonderful coral formations and large schools of neon-colored fish. You also have the option of scuba diving or sea kayaking in the mangroves. Then we had a glorious lunch of fried red snapper and an Aguila beer, before going for a dip in the warm waters and passing out on my chaise lounge chair. Several couples on our boat spent the night at Hotel San Pedro de Majagua, perfect for that romantic and very private retreat, especially when the daytrippers leave.
Many all-inclusive properties in the Caribbean offer some sort of a sunset snorkeling cruise, but I have to give a special shout-out to the captain and crew of Scuba Caribe at the 
Looking forward to seeing an ockie (octopus) in the bommie (coral head)? Then Heron Island, on the Great Barrier’s southern reef, is the place for you, mates. You might also dive with giant sea turtles that come ashore to lay their eggs between late October and March, or with humpback whales that skirt the island from June through October. 
A mere decade ago, Bonaire was known only to scuba enthusiasts—a clandestine gem discussed in hushed conversations with other serious ocean lovers (types who come out of the water with seaweed in their hair). Now that the secret is out, travelers are learning that nature thrives both above and below the water here. The reef’s proximity to shore is ideal for divers and snorkelers who want to swim with blue and yellow queen angelfish and orange trumpetfish in waters with visibility of 100 feet or more. On terra firma, Bonaire’s semi-arid landscape is home to some 200 types of birds, including one of the world’s largest colonies of pink flamingoes (numbering some 15,000). Situated on a small peninsula, the guest rooms at 
Picture yourself on a South Pacific island where the hum of cars and TVs is replaced by the sounds of waves tumbling ashore and the sporadic plunk of almonds dropping from trees. Envision a private island resort catering to only 14 couples. This is 
Let’s be serious. You’ve just traveled at least six hours from the West Coast to Hawaii, another seven hours to Guam and yet another 90 minutes to this cluster of 200 sparsely populated islands, which Cousteau called the best scuba diving site in the world. You’re going to have to get motivated to do much else but dive on Palau. From your home base on the capital isle of Koror, head to the Big Drop-Off, considered the best dive wall on Earth. It starts in knee-deep water and then abruptly plummets almost 1,500 feet into an abyss. Nearly as mind-boggling is Blue Corner, a large coral cavity where three ocean currents meet. Hunker down and watch schools of tuna, white-tipped sharks and 3-foot-tall giant clams (where’s the melted butter when you need it?). While you’ll have a tough time immersing yourself in traditional island culture here (read: no jerk chicken or Bo Derek-style hair braiding), Palau’s real attraction is its remote beauty. Rent a sea kayak and check out a few of the Rock Islands, which stretch for 20 miles south of Koror. Then dry off at the 
It’s cold, gray—the best time to put on a bathing suit and commune with fish.
Taveuni, Fiji, is one of those places like Palau or the Red Sea that is discussed only in clandestine conversations between avid scuba divers. They come here to dive the renowned Rainbow Reef, whose intricate corals and myriad fish provide divers with a kaleidoscopic view of the sea. Add white-tip sharks, sea turtles, and manta rays to the equation and you have one of the finest diving experiences in the world.

Of the thousands of people who take the quarter-mile walk from the cliffs of La Jolla Cove to Casa Cove, few take the plunge. Twenty feet below the surface, you’ll be hanging with harbor seals and 3-foot horn sharks (harmless) inspecting clumps of bright yellow sulphur sponges that cling to the wall.
