The planet’s great barrier reefs are world renowned for their colorful corals and teeming underwater wildlife. Sombrero reef is alive with activity – a submerged tropical paradise where angelfish glide among the living branches of pristine staghorn coral. Because the entire area is protected, large grouper and snapper thrive in the deep, while stingrays take wing overhead as though flying through the current.
At Starfish Marathon Snorkeling Tours we place you front-and-center in the action while ensuring that your ride on our custom catamaran is safe and comfortable. We don’t allow coolers or scuba gear on our Marathon snorkel tours because we want our guests to be able to move freely on deck without worrying about falling over obstructions or stubbing their toes. Our vessel is entirely covered so everyone on board is protected from the unforgiving Florida sun.
Bring your entire family on one of our fun-filled Marathon snorkel tours. See one of the planet’s most magnificent barrier reefs with your own eyes, and enjoy a wonderland of sights and sounds.
Marathon Snorkeling Tours at World-Famous Sombrero Reef
People travel from all over the world to snorkel in the Florida Keys. No snorkeling destination in the region is more famous than Marathon’s own Sombrero Reef, and with good reason. The 30 acre reef is thriving, and filled with incredible coral formations and massive schools of neon-colored tropical fish.
One of the reasons so many people join us on our snorkel adventures in Marathon is because Sombrero Reef is only 2 to 30 feet deep, so it can be thoroughly enjoyed without any fancy diving gear. Located in the Atlantic Ocean only six miles from Marathon’s shores, it’s easy to access and makes for an enjoyable ride where dolphins, turtles, and stingrays are often spotted en route.
Marathon Snorkel Tours
We urge all of our snorkeling guests to be aware of the rules that govern the reef, so that this treasure can be enjoyed by future generations. Coral is a living animal, and the clicking sounds you hear while snorkeling is the multitude of wildlife feeding in, around, and on the coral itself. Enjoy your snorkel adventure, but remember these basic rules:
- NEVER stand on the coral while snorkeling
- Use the buddy system – snorkel with a partner
- Swimming is a prerequisite for this activity – if you can not swim, ride along passengers are welcome
- Do not touch or take coral – it is against the law
Information About Our Marathon Snorkeling Vessel – The Starfish
We keep our boat obstruction-free so all of our passengers, both large and small, can fully enjoy their Marathon snorkel adventure. We operate three snorkeling trips throughout the season, so that you can choose a time of day that best suits your lifestyle.
The Starfish is a spacious, fully covered, luxuriously powered catamaran with a freshwater shower and a shaded lounging area. Your snorkeling gear is provided, but we also offer the following extras for your comfort and enjoyment:
- Underwater cameras
- Prescription mask rental (nearsighted only)
- Wetsuit Rental
- Earplugs
- New mouthpieces
- Sun lotion
- Motion sickness tablets
- Refreshments
We do not allow spray-on lotions of any kind on our Marathon snorkeling tours. The reason is because the overspray from these aerosols cause the deck to get slippery, and we don’t want an injury to ruin anyone’s snorkeling trip. This is also why we do not allow coolers or scuba gear onboard, because we want plenty of room for adults and kids to be able to fully utilize the deck.
