Reef dives

The classic dive and the reason most people start diving. You swim slowly over or along a coral reef, looking at fish, corals, turtles and invertebrates. Shallow reefs (5–18 m) have the most light and colour, and they're ideal for new divers. Places like the Red Sea, Bonaire and the Great Barrier Reef are famous for reef diving.

Wall dives

A wall is a reef that drops steeply or vertically into deep water, sometimes hundreds of metres. It's spectacular, often with sea fans, sponges and passing pelagic fish. The challenge is depth control: with no bottom beneath you, it's easy to drift deeper without noticing. Watch your computer, stay close to your buddy, and keep the wall on one shoulder.

Wreck dives

Ships, planes and even tanks rest on the seabed, some sunk in wars, others deliberately as artificial reefs. Wrecks attract huge amounts of marine life and history lovers. Examples include the SS Thistlegorm (Red Sea), the Zenobia (Cyprus), and the USAT Liberty in Tulamben (Bali), which is shallow and beginner-friendly.

Stay outside unless trained

Going inside a wreck (penetration) is an overhead environment with risks of entanglement, silt-outs and getting lost. It requires wreck training and appropriate equipment. Swimming around the outside is fine within your depth limits.

Drift dives

On a drift dive, you let the current carry you along the reef while the boat follows your bubbles or SMB. It's effortless and exhilarating, like flying past the scenery. Drift diving needs good buoyancy, group discipline, and surface signalling devices. Cozumel has famous gentle drifts; Komodo and parts of the Maldives have strong ones for experienced divers.

Night dives

After dark, the reef transforms. Hunting moray eels and lionfish, octopus and squid, sleeping parrotfish in mucus cocoons, crabs, shrimp and bioluminescent plankton when you cover your torch. Night diving usually starts at a site you already dived in daylight. You'll carry a primary and backup torch and learn light signals. It's a highlight for many divers, and part of most Advanced courses.

Muck dives

"Muck" refers to sandy or silty bottoms that look empty, but are full of strange, small creatures: frogfish, ghost pipefish, mimic octopus, colourful nudibranchs. Anilao in the Philippines and Lembeh in Indonesia are world famous. It's slow, relaxing diving, but it needs excellent buoyancy to avoid stirring up silt.

Deep dives

Recreational "deep" diving means 18–40 m. It gives access to certain wrecks, walls and big animals, but air consumption rises, no-decompression limits shrink, and nitrogen narcosis can impair your judgement. Open Water divers are limited to 18 m; the Advanced course takes you to 30 m, and the Deep specialty to 40 m.

Cavern and cenote dives

A cavern is the area of a cave where daylight is still visible and you're within a limited distance of the surface. Mexico's Yucatán cenotes offer spectacular guided cavern tours for certified divers with good buoyancy, following strict local rules and experienced cavern guides.

Cave dives

True cave diving, beyond the daylight zone, is technical diving. It requires full cave training, redundant equipment and strict protocols. Many untrained divers have died in caves. Never enter a cave without the proper training.

Other dive types

Shore dives: entering from the beach. See a day of diving.
Blue-water / pelagic dives: in open ocean, often to see sharks or mantas.
Kelp forest dives: in cooler temperate waters such as California and South Africa.
Altitude dives: in mountain lakes, requiring adjusted procedures.
Ice dives: specialist cold-water diving under ice.

Frequently asked questions

What is the easiest type of dive for beginners?

A shallow reef dive in calm, clear, warm water with little current is ideal for new divers.

Can Open Water divers do night dives?

Often yes, with a guide, but it's best after a few daytime dives. A night specialty or Advanced course teaches the specific skills.

Can beginners dive in the Mexican cenotes?

Certified Open Water divers with good buoyancy can join guided cavern tours at many cenotes. Some operators require more experience or specific courses.
