Are you ready for a half day adventure cruise in Duck Key?

This Duck Key half-day adventure cruise is all about sharing a memorable experience with your loved ones while on vacation. Bring the kids along for the experience of a lifetime on our custom 28-foot boat, Big B, which has a fantastic sun deck and double biminis for the enjoyment of all. The boat can accommodate 6 passengers.

Your 3,5-hour adventure begins at the Coffins Patch Reef with Captain Mark from Deadliest Catch for amazing snorkeling with schools of our colorful tropical fish. Then board the boat and travel to the Grassy Key Sandbar, where you can unwind in the crystal-clear water and fine sand, go swimming, and shell collect to your heart's content.

Just when you think you've seen everything, Captain Mark will take you to a special place called the Conch Shell Nursery and show you how to look for conch shells while exploring the shores of Duck Key. Bring your lunch and spend the day with Captain Mark as he talks about the ocean and how much he loves it.

The half-day adventure boat tour is fun for kids of all ages. In case you want to rest and relax, our comfortable boat has cushioned seating and a bimini for partial shade. Our friendly team will provide water, an ice chest, snorkel gear, and floatation. We recommend that you bring towels (no glass bottles), sunscreen, sunglasses, a hat, water shoes, snacks, and drinks.
