Fun Off The Beaten Path Tour

"Awesome time. The Kayaks were in great condition. There were lockers for our belongings. The tour guide was fun and energetic. They even brought along water and candy. Started with about a mile kayak through the mangroves. Then we hiked about .25 mile to a blowhole area that was stunning. Then we hiked back and snorkeled. The tour guide even pointed out fish, octopi, and barracudas. Then we kayaked the mile back. The water was gorgeous, the mangroves were cool and, again, the tour guide was fun and full of great knowledge."

Amazing day kayaking, hiking, and snorkeling!!

"This activity was a highlight of our trip to Saint Thomas! We kayaked, hiked, and snorkeled. We were so lucky and it was only our group of people on the tour - so it turned into a private tour. Our tour guide pointed out so many different fish/sea creatures while we were kayaking/hiking/snorkeling. It's so worth it to get the photo package because we didn't have to worry about bringing our phones with us and it was an underwater camera so we got some cool snorkeling photos. We'd definitely recommend this activity to anyone looking for an active adventure in Saint Thomas!"

Went back a second time because it was AWESOME!

"Our family booked this excursion again! It is a fabulous way to spend a few hours exploring St. Thomas, before or after shopping. The kayaking was just strenuous enough to work off some of those extra calories from the cruise. The hike was fun, and the guides were fabulous. Everyone in our group, from age 8 to 65, LOVED this excursion. The customer service department is AMAZING! Additionally, I scraped my shin on a rock, and the staff treated me as if I had a life threatening wound."
