Experience a private snorkeling adventure in Marathon, FL, with crystal-clear waters, vibrant reefs, and personalized service for a memorable day.

This review covers a private, customizable snorkeling trip in Marathon, Florida, offered by Seahorse Water Adventures. While we haven’t personally taken this exact trip, the package promises a relaxed, tailored experience in one of the Sunshine State’s best underwater playgrounds.
One aspect we love is the flexibility of a private tour, which means your group can set the pace and choose what’s most interesting to you. The other standout feature is the quality of the surroundings — clear waters, lively reefs, and an array of marine life that make for an unforgettable experience.
A potential consideration is the cost — at $325 for up to six people, it’s an investment, but one that offers a bespoke experience, away from crowded tours. This trip is ideal for ocean lovers, families, or small groups seeking a calm, personalized day exploring Florida’s marine environment.

This private snorkeling trip is designed to go beyond a typical group tour, giving you the chance to explore the underwater world in a calm, focused setting. For $325 per group (up to six), Seahorse Water Adventures offers a journey that balances comfort and adventure, emphasizing safety and customization. What truly sets this apart is that it’s not a cookie-cutter experience; it’s tailored for your group, providing flexibility in what you explore and how long you spend in the water.
The activity starts at 4650 Overseas Hwy, Marathon, FL, placing it within easy reach for those staying in the Keys. The meeting process requires arriving 15 minutes early to ensure smooth check-in, a small but important detail that helps keep the day on schedule. Since the tour ends back at the same spot, you won’t need to worry about transportation logistics.
Spanning approximately one day, this trip is a half-day adventure—long enough to see plenty without feeling rushed. The small group size (up to six people) means you’re not lost in a crowd, and the crew can give you more personalized attention. This is especially valuable if you’re new to snorkeling or want to learn specific skills or spots.
The package includes bottled water, snorkeling gear, and floats for relaxing, making it easy to prepare. You’ll need to bring your own towel, reef-safe sunscreen, hat, and sunglasses—items that might seem minor but significantly enhance comfort and safety on the water.
The use of reef-safe sunscreen is strongly recommended since it helps protect fragile coral ecosystems while allowing you to enjoy the sun without guilt.
Once aboard, your crew will prioritize your safety and comfort, guiding you through the waters to vibrant coral reefs bustling with marine life. Expect to see a variety of fish and coral, with the chance to spot other wildlife depending on conditions. The crystal-clear waters promise excellent visibility, perfect for photography or simply marveling at the underwater scenes.
The inclusion of floats offers a relaxing way to hang out between snorkels, giving you a break from swimming while still enjoying the scenery. The crew’s friendly attitude and professionalism will make you feel at ease, whether you’re a beginner or an experienced snorkeler.
Compared to standard group tours, the private custom approach ensures that your group’s interests and pace are prioritized. You won’t be stuck following a large crowd or rushing between sites. Instead, you can focus on what matters most to you—whether that’s exploring a particular reef or just floating and soaking up the sun.
The waters around Marathon are known for their vivid coral reefs and abundant marine life. One reviewer noted the trip’s “stunning views,” which highlight the appeal of this region. The reefs in this area tend to be lively and colorful, offering excellent opportunities for photography and close-up observation of fish and coral.
While this trip offers flexibility, it’s worth noting that weather conditions can affect the experience. Since the trip is weather-dependent, poor conditions may lead to cancellations or rescheduling. Seahorse Water Adventures offers full refunds if canceled due to weather, but last-minute cancellations within 24 hours mean no refund.
Also, at $325, this experience might seem more expensive than some mass-market tours. However, the personalization and small group setting add to the perceived value, especially for those who prefer a quieter, more tailored experience.

This adventure is perfect for small groups or families looking for a more intimate, customized trip. It’s well-suited for beginners, thanks to the crew’s emphasis on safety, but also attractive for experienced snorkelers wanting calmer, private reef exploration.
