The United States offers an unparalleled diversity of scuba diving experiences across an extraordinary range of environments, from the tropical coral reefs of Florida and Hawaii to the cold-water kelp forests of the Pacific Northwest, the freshwater shipwreck preserves of the Great Lakes, and the world-class cavern systems of the Florida springs. With coastlines on the Atlantic, Pacific, and Gulf of Mexico, plus the Caribbean territories of Puerto Rico and the US Virgin Islands and Pacific territories including Guam and the Northern Mariana Islands, the US encompasses virtually every type of diving on Earth. Florida alone provides over one thousand miles of reef systems, including the only living coral barrier reef in the continental United States, while Hawaii offers pristine volcanic underwater landscapes with endemic species found nowhere else. The Great Lakes hold thousands of remarkably preserved wooden and steel shipwrecks in crystal-clear freshwater, and the cold waters of the Pacific Northwest support giant Pacific octopus, wolf eels, and extraordinary invertebrate communities. The US diving infrastructure is among the most developed in the world, with professional dive operators, liveaboard fleets, artificial reef programs, and marine sanctuaries supporting divers of every certification level. From technical cave diving in the cenote systems of Florida to manta ray night dives off the Kona coast, from WWII wrecks in Guam's Apra Harbor to fossil hunting for megalodon teeth in South Carolina's blackwater rivers, the United States delivers a lifetime of underwater adventure.

Liveaboard diving in the US operates primarily in three regions: Hawaii for remote island diving and manta ray encounters, Florida for the Dry Tortugas and remote Keys reefs, and the Gulf of Mexico for Flower Garden Banks. Several operators also run expeditions to the US Pacific territories and remote California Channel Islands.

The United States is vast and domestic flights are essential for covering long distances between diving regions. Major airlines including American, Delta, United, and Southwest provide extensive networks. For regional exploration, rental cars are essential to reach dispersed dive sites. Amtrak rail service connects some coastal cities but is limited compared to other countries.
