Scuba Diving in April

Year-round Red Sea diving from shore at budget prices, with the famous Blue Hole and a dedicated learning community that makes Dahab one of the world's top divemaster training destinations. Immediate deep-water access without a boat separates it from every other dive town on the Red Sea.

Budget Caribbean reef diving on the Mesoamerican Barrier Reef — the second-largest in the world. PADI Open Water courses here are among the cheapest in the entire Caribbean. Whale sharks congregate at cleaning stations in spring, turtles are present year-round, and the wall diving off West Bay rivals anything in the region at a fraction of the cost.

The USAT Liberty — a 120m US Army cargo ship torpedoed in 1942 — lies just 30m from shore in 5-30m of water, encrusted in coral and surrounded by reef life. It is the most accessible major wreck dive in the world, and one of the best macro sites in Bali for pygmy seahorses, ghost pipefish, and nudibranchs.

Self-reliant divers' paradise. Rent a truck, load tanks, drive to any of 86 marked sites around the island, and enter from shore — no boat, no schedule, no guide required. The marine park is among the most strictly enforced in the Caribbean, which means coral health far exceeds comparable destinations. Divers routinely do 3-4 dives a day at their own pace.

The drift diving benchmark. Crystal Caribbean water at 30-60m visibility, warm temperatures year-round, and effortless drift along Palancar Reef and Santa Rosa Wall make Cozumel the most reliable introduction to drift technique and the easiest way to experience world-class Caribbean reef structure.

The only place on Earth where you can dive manta ray cleaning stations in the morning and watch Komodo dragons from a beach in the afternoon. Cold-water upwellings from the Indian Ocean fuel reef systems with exceptional fish density, and the range of dive environments — drift, wall, reef, muck — is unusually wide for a single park.

Egypt's most developed resort dive hub, with well-organized operations and easy liveaboard access to the SS Thistlegorm — the world's most dived wreck. Ras Mohammed National Park is 20 minutes by boat and delivers consistent shark, turtle, and reef encounters.

Blue Corner is the most celebrated dive site in Micronesia. Hook into the wall in 1-3 knots of current and watch grey reef sharks, whitetips, barracuda, and Napoleon wrasse pass at eye level. Add the largest WWII wreck graveyard in the Pacific, Jellyfish Lake, and German Channel manta cleaning station — Palau is the most complete advanced dive destination in the Pacific.

One of the last truly unexplored dive frontiers. Strict government permit limits mean very few boats operate here, and the reefs have never experienced the volume of dive traffic that affected the Egyptian Red Sea. Sanganeb Atoll produces hammerhead aggregations; Sha'ab Rumi has Jacques Cousteau's original research station visible on the reef.

Channel diving where open-ocean currents deliver whale sharks, manta rays, and schooling hammerheads through narrow underwater passages. Resort-based living with house reefs for easy multiple daily dives, and liveaboards for divers who want to cover the atoll spread. The most complete combination of luxury travel and world-class pelagic diving available.
