Marathon Florida offers some of the most appealing boat experiences in the Keys — whether you’re looking to unwind with a sunset drink or explore underwater reefs teeming with marine life. The Marathon Mermaid stands out as a versatile vessel, hosting both scenic cruises and snorkeling trips.
Our favorite? The Sunset Champagne Cruise offers a relaxing way to end your day with the classic combination of breathtaking views, champagne, and gentle music.
If snorkeling is more your speed, the Sombrero Reef adventure is highly regarded for exploring the vibrant underwater world of the third-largest barrier reef.
Both options showcase the Keys’ unique charm, but each caters to different interests—whether scenic relaxation or underwater discovery.
Marathon is perfect for boat enthusiasts because of its natural waterways, easy access to reefs, and calm harbors. You can enjoy serene cruising, lively snorkeling, or even both. With several well-rated tours available, it’s easy to tailor your experience. The list below highlights two of the best options, each offering a different way to enjoy the waters of the Florida Keys.
1. Florida: Sunset Champagne Cruise on the Marathon Mermaid
For around $82 per person, the Sunset Champagne Cruise offers a two-hour escape into the evening. This cruise is perfect for those wanting a romantic or peaceful way to experience the Keys’ famous sunsets. The Marathon Mermaid takes you through Boot Key Harbor, a calm waterway ideal for relaxing and taking photos.
As the sun dips, you’ll enjoy complimentary champagne, soft music, and panoramic views around the 7 Mile Bridge—one of the most iconic sights in the area.
Guests consistently praise the tranquil atmosphere and the picture-perfect moments created during sunset. The boat’s open deck allows for unobstructed views, making it perfect for photography or simply soaking in the scenery. The experience balances a leisurely cruise with enough time to enjoy drinks and conversation.
While it’s a short tour—just two hours—it’s often highlighted as the most romantic way to see the Keys at twilight.
Bottom Line: If you’re seeking a memorable, relaxing evening with stunning scenery and a touch of elegance, this cruise is hard to beat. It’s especially ideal for couples or anyone wanting a peaceful, scenic experience.
2. Marathon: Snorkeling Adventure by Boat at Sombrero Reef
For $89 per person, the Snorkeling Adventure at Sombrero Reef takes you on a three-hour journey into the vibrant waters surrounding Marathon. The tour includes top-rated snorkeling gear and a professional crew eager to guide you through the world’s third-largest barrier reef. The reef itself is a lively stop, packed with colorful corals, tropical fish, and even occasional sea turtles.
What makes this trip stand out is the quality of the equipment and the enthusiasm of the crew who aim to make every snorkeler comfortable and informed. Passengers are often told that the reef is teeming with marine life—including starfish, angelfish, and octopus—making it a fantastic choice for those wanting an immersive underwater experience.
The boat itself, the Marathon Mermaid, is described as luxurious yet practical, providing a smooth ride through clear, calm waters. After snorkeling, guests can relax with refreshments, fresh fruit, and light snacks during the return trip.
Many reviewers mention how the crew’s knowledge and friendly attitude enhance the experience. It’s best suited for those comfortable in the water, but the guided aspect helps beginners feel more confident.
Bottom Line: This tour offers great value for anyone eager to see the Keys’ underwater ecosystem up close, making it ideal for nature lovers and those new to snorkeling.
How to Choose
When deciding between these two excellent options, consider your priorities. If you want a serene, romantic experience with beautiful sunset views, the Sunset Champagne Cruise is perfect. It’s a shorter, more relaxed outing, ideal for evening relaxation or celebrating a special occasion.
If underwater exploration excites you, and you’re eager to see vibrant coral reefs and tropical fish, the Snorkeling Adventure at Sombrero Reef is your best bet. It offers a longer, more active day on the water with the chance to connect with marine life.
Budget-wise, both tours are reasonably priced considering the level of experience provided, but if you’re on a tight schedule, the sunset cruise’s shorter duration makes it easier to fit into a busy itinerary. Booking early is recommended, especially during peak holiday seasons.
Final Thoughts
Marathon Florida’s boat tours highlight the diversity of the Keys’ waters—whether you’re after stunning sunsets or underwater adventures. The Sunset Champagne Cruise offers a peaceful, scenic escape perfect for romantic evenings, while the Snorkeling at Sombrero Reef invites you to explore the vibrant marine environment up close.
For travelers seeking a gentle, scenic experience, the sunset cruise is a wonderful choice. Those looking to get their fins wet and see the reef’s colorful inhabitants will find the snorkeling tour more rewarding. Both tours reflect the laid-back charm and natural beauty of Marathon, so you can’t go wrong—just pick what suits your style and book early to secure your spot. Happy sailing.
