1. Aquatic Adventures: Living the Dream Divers, Seven Mile Beach, Cayman Islands

Divers of all abilities will be in their aquatic element on this coastal tour. Whether travelers prefer to take the plunge and scuba dive among sea turtles, nurse sharks, and moray eels, or simply snorkel in the shallow waters of "Stingray City," this tour caters to all seeking an ocean adventure.

"From the boat, to the people, to the service, it was all exceptional," a TripAdvisor traveler said. Tours cost from $65 per person.

2. Heart-Stopping Heights: Hang Gliding Interlaken, Interlaken, Switzerland

For thrill-seekers in the Swiss Alps, the sky is the limit with this over-the-top tour. Travelers can choose to enjoy a smooth, scenic flight or a wild ride with extreme dives and wingovers, while getting close to the clouds and taking in some breath-taking views of Switzerland. As proof of one's daredevil status, an in-flight DVD is available for purchase. As one TripAdvisor traveler commented, "It's a bird's eye view of one of the prettiest places on earth!" Tours cost $235 for a 10-25 minute ride.

After adrenaline levels fall back to Earth, adventurers can unwind in the emerald green waters of a jungle cenote. A TripAdvisor traveler said, "Tons of fun and worth every penny!" Tours cost from $99 for adults and from $49 for children.

5. The Wall Less Traveled: The Great Wall of Jiankou - The Great Wall Hike, Beijing, China

For travelers seeking seclusion and an adventure that is off the beaten path, the Jiankou Great Wall Hike is a giant step in the right direction. While the restored areas of China's Great Wall are easy to access and heavily traveled, tourists on this six-hour hike will experience untouched, isolated spots of this historic landmark. A sturdy walking stick is required, but the exclusive views make each step of the journey worthwhile. As one TripAdvisor traveler noted, "It's magical to be alone up on the Wall rather than surrounded by other tourists!" Tours cost from $180 to $275 per person.

"Absolutely the best tour company with the most awesome guides," noted a TripAdvisor traveler. Tours cost from $28 to $120.

7.  Rapid Rush: Jackson Hole Whitewater, Jackson Hole, Wyoming

This family-friendly white-water rafting tour features an eight-mile excursion down the Snake River allowing adventurers to paddle their way through the winding rapids or sit back and enjoy the spectacular scenery. Travelers up for a challenge can take part in an eight-person raft trip, during which raft-riders are required to pull their own weight while paddling vigorously along the twists and turns of the meandering river. "Best adventure in Jackson Hole," a TripAdvisor traveler said. The "Classic" tour costs $60 for children and $70 for adults; and $75 for the eight-man raft trip.

8. Slippery Stroll: Exit Glacier Guides, Seward, Alaska

This Alaskan tour company offers travelers an abundance of icy adventures, including an ice-hiking expedition which begins in Kanai Fjords National Park. Hikers should keep their eyes peeled as they ascend into the mountains and learn about the area's unique vegetation and glaciology – black bears, moose and marmots are often spotted along the trek. Those willing to explore further can embark on a glacier climbing junket, where they will gear up with the necessary apparel, before delving into the hidden crevasses of Alaska's frozen tundra. A TripAdvisor traveler described this tour as an "Out of the ordinary experience." Tours cost $125 per person.

Adventurers opting for a shorter outing can embark on the "Black Labyrinth" tour, which sees travelers climbing and tubing along a winding underground river surrounded by cascading waterfalls. A TripAdvisor traveler called this tour, "An amazing, unique experience!" Tours cost from $115 to $200 per person.
