Boat Vs. No Boat Options

When it comes to snorkeling in Marathon, Florida, you have a couple of options to consider: hopping on a boat or staying close to the shore. Each option has its own advantages and drawbacks.
Boat Snorkeling:
As someone who’s been lucky enough to always have a boat at my disposal when I’m in the Florida Keys, I can’t recommend enough the added flexibility and range it offers for snorkeling. It’s like having a VIP pass to the best underwater shows Marathon has to offer!
Boat Snorkeling is the way to go if you want to widen your horizons and immerse yourself in marine life and surreal coral formations. Top-tier boat tour operators like Captain Hook’s Marina offer impressive snorkeling charters. One of their crown jewels is a trip to Sombrero Reef, where the underwater scenery will make your jaw drop.
But wait, don’t have a boat? No worries at all! Visiting Marathon doesn’t mean you miss out on the boat-snorkeling experience. You can always rent a boat in the Florida Keys for an intimate, customized adventure at sea.
And if handling a boat sounds like too much hassle during your vacation, just hop onto one of the many snorkeling tours available.
We recommend this Marathon Snorkeling Tour if you don’t mind hopping on with others in the group.
And for those that prefer private charters, this one is a private charter from Key West (only about an hour’s drive from Marathon).
Whichever way you choose, you’re in for an unforgettable snorkeling escapade.
However, it’s important to note that boat snorkeling trips can be more expensive and may require reservations. Being in a group means sharing the boat and accommodations with strangers unless you opt for a private boat rental.
No Boat Snorkeling: If you prefer snorkeling directly from the shore, there are still great spots in Marathon to explore. One popular location is at Cannon Beach in Pennekamp State Park. Here, remnants of an early Spanish shipwreck can be found approximately 100 feet from the shore. While this may not compare to the reefs further out, it’s still a worthwhile experience and requires no boat.
Shore snorkeling is generally more budget-friendly and allows for a more flexible schedule since there’s no need to align your plans with tour times. That being said, the marine life and coral formations won’t be as extensive or diverse as those found on boat trips.
In summary, your choice between boat and no boat snorkeling in Marathon, Florida will largely depend on your preferences, budget, and time constraints. Whether you go for a boat tour or decide to snorkel from the shore, you’re sure to have an unforgettable underwater adventure.
Snorkeling Equipment and Safety Tips

Before embarking on your snorkeling adventure in Marathon, Florida, it’s crucial to ensure that you have the proper snorkeling equipment and are aware of various safety tips. This will not only make your experience more enjoyable but also keep you safe while exploring the underwater world.
Firstly, invest in quality snorkel gear, including a well-fitting mask, snorkel, and fins. A properly fitted mask will provide a comfortable seal around your face and prevent water leakage. The snorkel should have a reliable purge valve, making it easier to clear water from the tube. Comfortable fins will allow you more efficient movement in the water, enabling you to cover greater distances in less time.
As you prepare to dive in, make sure to use a dive flag to signal your presence to boats and other watercraft in the area. This is essential for your safety, particularly if you plan on snorkeling near a busy waterway. Keep an eye out for your fellow swimmers and maintain a safe distance from them to avoid collisions.
While exploring the underwater world, don’t disturb the delicate marine life. Avoid touching or standing on rock shelves or coral formations as these can be easily damaged. Underwater cameras are an excellent way to capture the beauty of the ocean without causing harm.
Keep in mind that fishing, lobsters, and some other underwater activities may be subject to local regulations and restrictions. Before participating in these activities, familiarize yourself with the applicable rules and regulations.
When it comes to safety, remember to never snorkel alone. Always bring a buddy and maintain visual contact with each other throughout your excursion. Additionally, stay within your limits and avoid venturing too far from shore or into unfamiliar waters.
Finally, although snorkeling is generally considered safe for people of all ages and fitness levels, certain health considerations should be taken into account. Those with heart or respiratory conditions, or a limited ability to swim, may want to consult a doctor before participating in snorkeling or scuba diving.
By following these tips and using the appropriate equipment, you’ll be well-prepared to safely and confidently enjoy your snorkeling experience in Marathon, Florida.
