Key Largo Reef Snorkeling & Two-Tank Boat Dive

The reefs here are part of the Florida Keys National Marine Sanctuary, one of the most biodiverse marine environments in North America. You can commonly spot parrotfish, spiny lobster, eagle rays, spotted eagle rays, sea turtles, nurse sharks, and barracuda. The reef structure consists of over 80 species of stony and soft coral and is home to hundreds of species of tropical fish. Sightings vary by season, water conditions, and site — but there's always something to see on these reefs.

Your guides visit a rotating selection of more than 100 sites across seven reef systems. Frequent destinations include Molasses Reef (one of the most vibrant coral reefs in the Keys), French Reef, the Christ of the Abyss Statue (one of the most photographed underwater statues in the world), and Grecian Rocks. The specific sites visited each day depend on conditions and your guides' assessment — they always aim for the best experience.

Key Largo is known for calm, clear waters and excellent visibility, especially in the summer months. The shallow reef sites are ideal for snorkeling and beginner diving — most are accessible at relatively shallow depths. Visibility can range from good to exceptional depending on weather, tide, and season. March can be more variable, while summer tends to offer the best conditions.

Yes. Certification cards are checked for all scuba divers before boarding the Sea Dweller III. If you have misplaced your physical card, many agencies now offer digital cards through their apps — confirm with your certifying agency. Non-certified guests are welcome as snorkelers, boat riders, or Discover Scuba participants (see separate listing).

Yes — all snorkelers must be able to swim and be comfortable in open ocean. Pool noodles are available in limited quantities for additional buoyancy. Snorkel vests are included and are a great tool for those still building comfort in open water.

You cannot wear glasses with a snorkel mask, but contact lenses work great and are often the best option for clear underwater vision. Prescription masks are available for an extra free from strengths -1.5 through -6. Fun fact: everything appears about 25% larger and closer underwater, which helps even without correction.

Reef-safe sunscreen is required. Common sunscreens contain chemicals like oxybenzone, octinoxate, and parabens that are absorbed by corals and cause bleaching and toxicity. Reef-safe formulas avoid these ingredients. For the best protection, look for "non-nano" mineral sunscreen, which uses particles too large to be absorbed by coral. Your crew will check labels before boarding — reef-safe sunscreen is also available on the boat.

You can snorkel with a beard or mustache, but facial hair can prevent a tight seal between the mask and your face, which may cause water to leak in. It is often recommended to shave at least your mustache before your trip. If you'd prefer not to, bring petroleum jelly or chapstick — coating your mustache before putting on the mask may help create a seal.

Ok so you decided to hire a guide, now what? You need to decide whether you would like to be with a Private Guide or a Non-Private Guide. What's the difference? Our Non-Private Guides are a GREAT cost effective option for getting a great tour of the dive site and having one of our PHENOMENAL dive pros show you where the resident critters typically hang out as well as not having to keep track of navigation, depth, time, etc. All you have to do is follow your guide and check out the cool stuff they show you while mainly just having to tell them how much air you have as they periodically check on your supply. As the cost effective option, our Non-Private guides could have several other divers in their group. We try to limit the number of divers to no more than 6-7 per guide but sometimes depending on the circumstances might push it to 8 if absolutely necessary (ex, 2 groups of 4 or something along those lines). But there is the possibility of differing levels of skill, experience, ability, etc. and it's the guide's responsibility to #1 keep all divers safe and #1.1 show you an amazing time. So if someone is an air hog and you don't get as much bottom time as you would like, or someone has trouble equalizing and has to go back to the boat, etc., you may possibly experience some of the technical difficulties that come with diving with other unknown divers. If something like that happens, usually, the guide will bring the group to the surface and ensure the diver with issues gets safely back to the boat and then if time and air supply permit, will take the rest of the group down to resume the dive. Our Non-Private guides are PERFECT for divers who would like to be guided but save some money, divers that are very comfortable or experienced and would rather have someone else navigate or show them the hidden gems on the sites and divers who don't have a buddy and needed to hire a guide to join the trip. Our Private Guides cost a few bucks more, but you get WAY more. Our private guides are the exact same Dive Pros as our non-private guides and will still give you the same great tour and keep track of everything for you like navigation, depth, time, but since they are focused on you and your buddy/group ONLY, there is WAY more personalized attention and flexibility with planning the dive as you are the ONLY ones they are paying attention to. Private Guides are PERFECT for divers that have a bit of budget flexibility, divers who don't want to share their dive with strangers but still want a guide, divers who want/need extra assistance/attention and divers who want to be pampered and spoiled.

In order to dive with Sea Dwellers, it is required to have a dive buddy. If you don't have a dive buddy joining you, we will paid you up with an 'insta-buddy' if we have any other solo divers that didn't opt to be guided. If, at check-in time, there are no other solo divers on the trip, you will be required to pay for a guide. In the event that you do not wish to pay for the guide, you will not be able to join the trip and we will not be able to provide a refund as our solo diver policy is stated on our website, online booking platform, all confirmation emails, reminder emails and is clearly stated during all phone reservation calls.
