Snorkeling is a delightful way to experience marine life—or to enjoy a clear lake or river from the surface—but for certified scuba divers there’s a unique thrill in donning a tank and descending for a closer look at the underwater world. Below are three outstanding scuba diving experiences around the globe, each offering a distinct environment and unforgettable encounters, from historic shipwrecks to graceful wild dolphins and impressive shark aggregations.
Read on for three incredible scuba diving tours in different environments around the world that take you from ghostly shipwrecks that are war graves to thrilling dolphin encounters in the wild.
DIVE AMONG WORLD WAR II WRECKS
Odyssey Adventures invites experienced divers to Micronesia aboard its 132-foot liveaboard for a week of continuous diving through Truk Lagoon. This remote lagoon is the final resting place for more than 60 Japanese vessels sunk during intense battles in 1944. Many wrecks remain hauntingly intact, and divers can sometimes encounter artifacts such as personal items and uniforms—reminders that these sites are wartime graves. At the same time, the wrecks have become vibrant reefs: soft and hard corals encrust hulls, schools of tropical fish weave through openings, and marine life has reclaimed these relics. Diving Truk Lagoon offers a profound mix of history, reverence, and thriving underwater biodiversity.

DIVE WITH WILD DOLPHINS
Of all marine mammals visible from shore or offshore, dolphins are often the most commonly seen—but encountering them while scuba diving is a rare and moving experience. In the Tuamotu Archipelago, French Polynesia, Rangiroa Diving Center offers guided dives at Tiputa Pass on Rangiroa atoll, where strong currents funnel nutrients and attract abundant marine life. Experienced divers can join passive, respectful encounters with resident dolphins that patrol the deep-blue waters at the atoll’s edge. Swimming alongside these intelligent, fast-moving animals is a memorable, breath-stealing experience that highlights both their curiosity and agility.
SWIM AMONG SAND TIGER SHARKS
Shark diving is a sought-after experience for many travelers, with destinations like Fiji, the Bahamas, and the Galápagos widely celebrated for their shark populations. However, the U.S. East Coast offers exceptional opportunities too: North Carolina’s Crystal Coast and Morehead City host regular dives to offshore wrecks populated by sand tiger sharks. Olympus Dive Center runs trips to these sites, where sand tiger sharks often swim with their mouths slightly open, creating dramatic photo opportunities that showcase their rows of teeth. On the 412-foot wreck of the tanker Papoose, sunk in 1942 by a German U-boat, divers can encounter impressive aggregations—sometimes as many as 20 sand tiger sharks on a single tank—making for a thrilling and photogenic dive.
