Reef Diving

Most Reef dives around Key West are at 20 – 40 feet (6 -12 meters), with water temperatures ranging from 87 F (summer) to 68 F (winter), visibility normally is 40-60 feet, with days of 75-100 foot visibility not uncommon. We have 30 to 40 plus different sites to choose from; our captains may make the choice on any given day depending on conditions and visibility of which sites offer the best diving. INNER REEFS – 3 ft. to 30 ft. depth. The inner coral reefs are a thrill to snorkelers and scuba divers alike! These extensive reefs are abundant in coral and marine life, with lots of available light and maximum dive time. OUTER REEFS – 35 ft. to 45 ft. depth. The outer bar provides a slightly deeper dive on beautiful coral formations. These reefs offer some of the nicest corals, gorgonians and larger fish found in the Florida Keys. Easy to navigate and loads of fun and an underwater photographers dream; professional and amateur alike.

Wreck Diving

Whether you’re a novice or a professional diver, we guarantee you the time of your life diving in the Florida Keys with Adventure Watersport Charters.

The Florida Keys are literally littered with wrecks from the beginning of the Keys to as far south as Key West, the Marquesas Keys and the Dry Tortugas, a true scuba diver’s dream! Many wrecks in Key West and further south have been sunk over the years either by accident or by deliberate scuttling with the aim of creating an artificial reef. Key West is home to the second largest artificial reef in the world, and the Gen. Hoyt S. Vandenberg wreck, which is accessible to divers of all levels. The wrecks of Key West host a wide variety of marine life including many corals, goliath groupers, moray eels, turtles, and rays. So whether you’re a novice looking to do a shallower wreck or an experienced diver looking for adventure on one of the deeper wrecks, we have scuba diving trips that will fit your experience levels.


Book your trips early for this one as the island and our boats fill up fast for lobster “mini” and regular season. The two day spiny lobster sport season runs the last consecutive Wednesday and Thursday of July, and the regular season is August 6th through March 31, but the summer months are when everyone gets serious about “bug” hunting. Diving for lobster in prime lobster season is an unforgettable experience not to mention the great feast at the end of the day!


The excitement of scuba diving, checking out a wreck and spearfishing one of the big bottom fish all at the same time is a adventure matched to non other! The remote areas of Dry Tortugas, the Tortugas Bank, the Marquesas Keys, and the wrecks offer superb spearfishing conditions. Average visibility is 50′ to 70′. Average depth is 60′ and the currents are not strong. We do mostly drift diving so you can cover more bottom and not have to repeat the same areas twice.
