Recreational dive sites are specific places that recreational scuba divers go to enjoy the underwater environment or for training purposes. They include technical diving sites beyond the range generally accepted for recreational diving. In this context all diving done for recreational purposes is included. Professional diving tends to be done where the job is, and with the exception of diver training and leading groups of recreational divers, does not generally occur at specific sites chosen for their easy access, pleasant conditions or interesting features.
Recreational dive sites may be found in a wide range of bodies of water, and may be popular for various reasons, including accessibility, biodiversity, spectacular topography, historical or cultural interest and artifacts (such as shipwrecks), and water clarity. Tropical waters of high biodiversity and colourful sea life are popular recreational diving vacation destinations. South-east Asia, the Caribbean islands, the Red Sea and the Great Barrier Reef of Australia are regions where the clear, warm, waters, reasonably predictable conditions and colourful and diverse sea life have made recreational diving an economically important tourist industry.
Recreational divers may accept a relatively high level of risk to dive at a site perceived to be of special interest. Wreck diving and cave diving have their adherents, and enthusiasts will endure considerable hardship, risk and expense to visit caves and wrecks where few have been before. Some sites are popular almost exclusively for their convenience for training and practice of skills, such as flooded quarries. They are generally found where more interesting and pleasant diving is not locally available, or may only be accessible when weather or water conditions permit.
While divers may choose to get into the water at any arbitrary place that seems like a good idea at the time, a popular recreational dive site will usually be named, and a geographical position identified and recorded, describing the site with enough accuracy to recognise it, and hopefully, find it again.

Reef dive sites
In the context of recreational diving, a reef may be a coral reef or a bottom of predominantly consolidated inorganic material, like rocky reef, and in the broader sense includes artificial structures and even ships sunk as artificial reefs.
Reef diving regions are geographical regions of arbitrary size known for including more than one named reef dive site, while a reef dive site is a specific part of a reef known by a name, which recreational divers visit to dive.
Many cave dive sites are fresh water, but there are some that are sea water and a few that are partly fresh and partly sea water, and these may have a distinct halocline.

Wreck diving is recreational diving where the wreckage of ships, aircraft and other artificial structures are explored. The term is used mainly by recreational and technical divers. Professional divers, when diving on a shipwreck, generally refer to the specific task, such as salvage work, accident investigation or archaeological survey. Although most wreck dive sites are at shipwrecks, there is an increasing trend to scuttle retired ships to create artificial reef sites. Diving to crashed aircraft can also be considered wreck diving. The recreation of wreck diving makes no distinction as to how the vessel ended up on the bottom.
USS Bonefish(SS-223) was a Gato-class submarine, the first United States Navy ship to be named for the bonefish.
USS Albacore (SS-218) was a Gato-class submarine which served in the Pacific Theater of Operations during World War II, winning the Presidential Unit Citation and nine battle stars for her service. During the war, she was credited with sinking 13 Japanese ships and damaging another five; not all of these credits were confirmed by postwar Joint Army–Navy Assessment Committee (JANAC) accounting. She also holds the distinction of sinking the highest warship tonnage of any U.S. submarine. She was lost in 1944, probably sunk by a mine off northern Hokkaidō on 7 November.
USS Snook (SS-279), a Gato-class submarine, was the first ship of the United States Navy to be named for the common snook, an Atlantic marine fish that is bluish-gray above and silvery below a black lateral line.
USS Grayback (SS-208), a Tambor-class submarine, was the first ship of the United States Navy to be named for the lake herring, Coregonus artedi. She ranked 20th among all U.S. submarines in total tonnage sunk during World War II, with 63,835 tons, and 24th in number of ships sunk, with 14. She was sunk near Okinawa on 27 February 1944. Her wreck was discovered in June 2019.
USS Harder(SS-257), a Gato-class submarine, was the first ship of the United States Navy to be named for the Harder, a fish of the mullet family found off South Africa. One of the most famous submarines of World War II, she received the Presidential Unit Citation. Her commanding officer throughout her service, the resolute and resourceful Commander Samuel D. Dealey (1906–1944), "a submariner's submariner", was posthumously awarded the Medal of Honor, as well as four Navy Crosses during his lifetime.
USS Bluegill (SS-242/SSK-242) was a Gato-class submarine in commission in the United States Navy from 1943 to 1946, from 1951 to 1952, and from 1953 to 1969. She was named for the bluegill, a sunfish of the Mississippi Valley.
HMCS Yukon was a Mackenzie-class destroyer that served in the Royal Canadian Navy (RCN) and later the Canadian Forces. She was the first Canadian naval unit to carry the name. She was named for the Yukon River that runs from British Columbia through Yukon and into Alaska in the United States.
A target ship is a vessel — typically an obsolete or captured warship — used as a seaborne target for naval gunnery practice or for weapons testing. Targets may be used with the intention of testing effectiveness of specific types of ammunition; or the target ship may be used for an extended period of routine target practice with specialized non-explosive ammunition. The potential consequences of a drifting wreck require careful preparation of the target ship to prevent pollution, or a floating or submerged collision risk for maritime navigation.
Imperial Japanese Navy submarines originated with the purchase of five Holland type submarines from the United States in 1904. Japanese submarine forces progressively built up strength and expertise, becoming by the beginning of World War II one of the world's most varied and powerful submarine fleets.
I-26 was an Imperial Japanese Navy B1 type submarine commissioned in 1941. She saw service in the Pacific War theatre of World War II, patrolling off the West Coast of Canada and the United States, the east coast of Australia, and Fiji and in the Indian Ocean and taking part in Operation K, preparatory operations for the Aleutian Islands campaign, and the Guadalcanal campaign, the Marianas campaign, and the Battle of Leyte Gulf. She was the first Japanese submarine to sink an American merchant ship in the war, sank the first ship lost off the coast of State of Washington during the war, damaged the aircraft carrier USS Saratoga(CV-3), sank the light cruiser USS Juneau(CLAA-52), and was the third-highest-scoring Japanese submarine of World War II in terms of shipping tonnage sunk. Her bombardment of Vancouver Island in 1942 was the first foreign attack on Canadian soil since 1870. In 1944, I-26′s crew committed war crimes in attacking the survivors of a ship she sank. She was sunk in October 1944 during her ninth war patrol.
I-21 was a Japanese Type B1 submarine which saw service during World War II in the Imperial Japanese Navy. She displaced 1,950 tons and had a speed of 24 knots (44 km/h). I-21 was the most successful Japanese submarine to operate in Australian waters, participating in the attack on Sydney Harbour in 1942 and sinking 44,000 tons of Allied shipping during her two deployments off the east coast of Australia.
USAT Liberty was a United States Army cargo ship torpedoed by Japanese submarine I-166 in January 1942 and beached on the island of Bali, Indonesia. She had been built as a Design 1037 ship for the United States Shipping Board in World War I and had served in the United States Navy in that war as animal transport USS Liberty (ID-3461). She was also notable as the first ship constructed at Federal Shipbuilding, Kearny, New Jersey. In 1963 a volcanic eruption moved the ship off the beach, and Liberty's wreck is now a popular dive site.
Sinking ships for wreck diving sites is the practice of scuttling old ships to produce artificial reefs suitable for wreck diving, to benefit from commercial revenues from recreational diving of the shipwreck, or to produce a diver training site.
I-74, later I-174, was an Imperial Japanese Navy Kaidai type cruiser submarine of the KD6B sub-class commissioned in 1938. During World War II, she took part in the attack on Pearl Harbor, the Battle of Midway, the Guadalcanal campaign, the New Guinea campaign, and the Gilbert and Marshall Islands campaign and operated off Australia before she was sunk during her ninth war patrol in 1944.

Kizugawa Maru, or Kitsugawa Maru, is a World War II-era Japanese water tanker sunk in Apra Harbor, Guam. Damaged by a submarine torpedo attack off Guam on April 8, 1944, she was towed into port for repairs. In port, she was further damaged in three separate U.S. air attacks during the Mariana and Palau Islands campaign. Deemed irreparable, Kizugawa Maru was scuttled by shore guns on June 27, 1944. The shipwreck is now a deep recreational diving site.
