The Cayman Islands are easily one of the Caribbean's most enthralling destinations, with all three islands (Grand Cayman, Cayman Brac and Little Cayman) being awash in gorgeous beaches, resplendent resorts and the famous friendliness of its locals.Your travel agent may also be able to set you up on one of the several adventurous travel excursions available in the Caymans, which are all bound to put a fun exclamation point on your trip:See Stingray CityIf swimming with stingrays wasn't on your bucket list before your trip to the Cayman Islands, it will be soon after you arrive. Stingray City is one of the most talked about sights in the islands, and no trip here is complete without seeing it in person.More an "offshore marine life development" than a genuine municipality, Stingray City is the nickname of a large gathering of stingrays at a sandbar off the coast of Grand Cayman. While no one is certain why they congregate here—the most popular theory being that local fisherman used to empty their nets at this precise spot and their scraps attracted the stingrays—everyone agrees Stingray City is a great time.An excursion allows you to frolic on the sandbar with the stingrays, swim alongside them and even feed them. Most people are able to get up-close-and-personal enough to brush up against the creatures—a unique sensation to say the least.WATCH: Cayman Islands: Immerse Yourself in Pure LuxuryMake for the Mastic TrailFor those active travelers who like to mix in a little cardio with their "R & R", then a ramble across the magnificent Mastic trail on Grand Cayman is the adventurous pursuit for you.The two-mile-long path cuts through a vibrant landscape which shows off the best of the Cayman Island's largest surviving swath of remaining native forest.
