Although the name, Micronesia, makes this wide swath of the north Pacific sound like a small state, it stretches across more 3,200 kilometers/2,000 miles of ocean, comprising several different countries and hundreds of islands. Included in the area known as Micronesia are true superstars of the dive world: Palau, Yap, Chuuk and Guam. Palau has been called one of the "Seven Underwater Wonders of the World" and has so many dive sites that belong at the top of your wish list, it's hard to know where to start. You'll find everything from World War II (WWII) wrecks to shark and manta cleaning stations to caverns. A close neighbor to Palau, Yap is one of the world's top places for guaranteed manta ray encounters in Mi'il Channel, along with walls, sharks, and macro wonderlands. Yap also has one of the world's most intact cultures where ancient stone money is still commonly seen. The major hub for Micronesia is Guam, which is littered with both World War I and WWII wrecks, some right on top of the other. And, of course, you need only to be a certified diver for about five minutes before you hear about the wrecks of Chuuk (Truk) Lagoon, all the aftermath of Operation Hailstone. Between dives, Micronesia exudes tropical splendor, with cultural and natural heritage that includes secluded island beaches and explosive sunsets.

Sea Turtles:

Hawksbill and green turtles can be found swimming in leisurely fashion or napping under ledges on most reefs.


These striking, wildly-patterned macro fish come out just before dusk and mated pairs rise above the reef in an unforgettable dance.
