Surfing, kayaking, mountain biking — they’re those adventure passions that, when combined with scuba, make a trip first-rate.

1. Costa Rica: Surf
“The most exciting thing about Costa Rica is that you can surf 360 days a year in board-shorts,” says Christian Boos, owner of Ollie’s Point Surf Camp in the Guanacaste province on the Pacific coast. In addition to picking up guests from nearby resorts, including Ocotal Beach Resort, Boos runs boat trips to offshore breaks like Witches Rock. This spot in Santa Rosa National Park breaks to the left and right, providing opportunities for riders of both preferences. For beginners, Tamarindo is tops. And the diving? You’ll encounter schools of hammerheads, manta rays and other denizens of the deep. Go Now: Ocotal Resort

2. St. Croix: Horseback Ride
Just as guides who dive the same sites regularly see faces and animals in oddly shaped sponge or coral heads, so too does Jill Hurd, among the trees she passes on her guided horseback tours on the west side of St. Croix. Hurd takes pride in pointing out the wonders of the rainforest, from the spikes of the monkey-no-climb tree to the pods of the tamarind tree, used as an ingredient in A.1. Steak Sauce. From where she leads horses on the beach, guests can see the dive site Spratt Hall, one of St. Croix’s most colorful. Go Now: St. Croix Scuba

3. Maui: SUP
From her paddleboard, Peg Alm, proprietor of Paddle On Maui, keeps her GoPro camera trained on a mother humpback and calf as they appear hundreds of feet below, surfacing yards from her feet. When she describes the encounter, she’s embarrassed by her outburst — but can you blame her? This is paddleboarding on Maui. Yes, Hawaiian green sea turtles make cameos hourly and, occasionally, manta rays. But humpbacks are the main attraction, encountered on nearly every board session mid-December to mid-April. But you most likely won’t see them with a tank strapped to your back. “Not many divers get that experience here,” says Rich Carman, manager at Maui Dive Shop. “I’ve known a few people who’ve been lucky — really lucky.” But under the sea, there’s big bounty when it comes to spotted eagle rays, whitetip reef sharks and, yes, more green sea turtles. In other words, plenty to scream into your regulator about. Go Now: Maui Dive Shop

4. Bonaire: Windsurf
If you’re looking to split your hours on Bonaire between scuba diving and windsurfing, just look at a windsock. Every afternoon the breeze picks up. And it’s strong. The place to go for lessons, gear rental or just a cold one while watching others catch air is Lac Bay, a shallow but wide cove on the island’s east side. “It’s protected by mangroves,” says Martin Cicilia, assistant manager at Buddy Dive Resort. “So it’s also nice for kayaking and snorkeling.” As for Cicilia’s days off, you’ll find him windsurfing. “I dive all week — five days — and spend the other two windsurfing.” Good time management indeed.

5. Thailand: Bike
After a week aboard Thailand Aggressor, with the snacks and the hardest hikes re- quiring just five steps to the put-in on some of the best diving in the world, you might need extra treadmill miles back home. Or, take a detour to the country’s northern interior. With Mountain Biking Chang Mai, you can opt for an all-downhill trek or something more challenging. The jungle scenery and mist-shrouded backdrop of Doi Suthep-Pui National Park are inspiring, and all you have to do is choose from such options as the city cultural ride and one nicknamed the Eliminator.

6. Grand Cayman: Kitesurf
A barrier reef encircles all of Grand Cayman — it’s where wall dives begin, and it’s the point of impact for breaking waves, creating a ring of flat water around the island. It’s in this in-between channel that newbie kitesurfers learn to tear it up. “Even on the windiest days, that water is calm,” says Mike Minichiello, manager of on-island kitesurfing shop the Sweet Spot. As for other reasons to visit Grand Cayman, divers know that below the waves are jaw-dropping walls and the wreck of the Kittiwake. Go Now: Divetech

7. Grand Bahama: Kayak
“Two-thirds of the island is just wild,” says Erika Gates. Along with her husband, she operates Grand Bahama Nature Tours, an outfitter that offers bike, snorkel, bird, ATV and kayak excursions. For paddlers, Gates recommends the Lucayan National Park Kayak and Nature Tour. For 90 minutes guests weave through mangrove tunnels, where Gates will point out birds and other fauna. The mangroves serve as a nursery for juvenile reef fish, and as a diver, you can’t help but gain an appreciation for the delicate balance between the ecosystems. Go Now: UNEXSO

8. Belize: Rappel
Ian Anderson’s Caves Branch Jungle Lodge, a resort and adventure company based in Belize’s interior, names the Black Hole Drop as one of its signature tours. After a 90-minute hike through howler-monkey habitat, it’s time to don helmet and harness. With your back to the abyss, you free fall and enjoy a surprisingly relaxing rappel through pristine rainforest. It’s an adrenaline-soaked complement to that other lush forest — the soft corals and sponges providing sanctuary to loggerhead sea turtles and nurse sharks. Go Now: Aggressor Fleet

9. Bermuda: Golf
“What surprises a lot of first-time visitors is our hills — we’re a volcanic island,” says Anthony Mocklow of Bermuda. The director of golf at the Fairmont Southampton, Mocklow says that “the elevation, the wind, the terrain — it all makes golf competitive.” Bermuda’s pace adds to its appeal: There’s no traffic, crowds, neon lights or anything associated with rush. It doesn’t hurt that for guests staying at the Fairmont, Dive Bermuda is just a few hundred yards from the pro shop. Those looking to honor two pastimes can dive in the morning, break for lunch, and then play 18 holes before sunset. Go Now: Blue Water Divers

10. British Virgin Islands: Sail
The trimaran S/Y Cuan Law ventures to more-remote sites of the BVI during weeklong trips. “We go out to the Chikuzen probably more than anyone else,” says owner Duncan Muirhead of the refrigeration ship 12 miles northwest of Virgin Gorda. “We’re also licensed to go to Anegada and visit the Parramatta.” Parramatta sank on its maiden voyage, and is just one of the secrets you’ll uncover when hopscotching these islands.
