View MapMicronesia


The area of the Pacific that is home to the islands of Micronesia is expansive and has a list of adventures to match. A hotbed of activity during World War II, these islands are home to some of the world’s most famous wreck dives. Truk Lagoon tops the list with more than 100 wrecks from “Operation Hailstorm” including the 500-foot Shinkoku Maru and 437-foot Fujikawa Maru. In addition to World War II wrecks and incredible reef diving, the Palau archipelago has unique excursions including Jellyfish Lake, where you can swim or snorkel among millions of non-stinging creatures, an experience not-to-be-missed. Micronesia’s culture also runs strong throughout the islands but perhaps Yap provides the one of the best opportunities to experience their unique way of life. Here you can stroll down stone paths through villages where mammoth exhibits of stone money denote wealth and social standing of its owner. But as incredible as this cultural experience is, it is the diving around Yap that attracts most visitors and the opportunity to dive with its population of resident manta rays. Divers can supplement their manta encounters with incredible wall, pass and cavern dives.

Micronesia Information

Diving in Palau, Yap & Truk

The Republic of Palau is Micronesia's western most island chain. The tightly clustered Palau archipelago, consists of over 200 islands covering a distance of around 125 miles. Palau is the home to one of the world's unique phenomena, the Rock Islands.

The Rock Islands are Palau's crowning glory. More than 200 of these jungle-topped knobs of limestone dot the waters for a 20 mile stretch south of Koror. Their bases, having been worn away by tidal action and grazing sea creatures, are narrower than their tops, causing them to look like emerald-hued mushrooms rising from the turquoise sea.

Palau has three ocean currents converging in its waters to bring in some of the most varied and dazzling marine life in the world. Palau is the last word in underwater wonderlands: it offers an endless variety of sites to dive - from caves to walls and major drop-offs, to tunnels, channels and shallow reefs, where you can enjoy great visibility and an almost limitless variety of marine life. Dive sites like Blue Corner and German Drop-off are known far and wide, as some of the best dive spots in the world.

Palau also features some of Micronesia's richest flora and fauna, both on land and beneath the waves, including the world famous Jellyfish Lake, which has millions of non-stinging jellyfish pulsating through the water.

The weather is hot and humid, with annual rainfall around 150 inches. The flora and fauna are tropical, but Palau is best known for its 70-mile-long barrier reef which encloses spectacular coral reefs and a lagoon of approximately 560 square miles, a divers' paradise. Palau's water temperatures remain above 82°F year-round, much to divers' delight.

Yap's famous manta rays and the diverse marine life that make their home in Yap's coral reefs and tidal channels have made Yap one of the fastest growing diving destinations in the world today.

The clear waters and sheer drop-offs make for a spectacular variety of diving experiences, but the divers all come for one thing: Yap is the world capital of manta ray diving. More than 45 individual mantas have been identified and given individual names, each easily recognized by the distinct markings.

Mantas are by no means all that Yap has to offer divers. Yap is located below the Pacific typhoon belt and for the same reason the mantas are on show year-round, divers can dive all year in consistent conditions. Reef sharks and big oceanic greys regularly patrol Yap's fringing reefs and have made several new sites and walls popular on the east and southeast coast. These sites also offer caverns, large gorgonian and fan corals, numerous varieties of reef fish and schools of tuna and jacks. Eagle rays also school in several areas in shallow water providing yet another exciting photographic and diving experience for divers visiting these legendary waters.

Culture and Customs

The people of Yap are proud and secure in their culture and traditions, which have been incorporated into daily life in the 21st century.

Village life centers around majestic Men's Houses where the local Chief conducts village meetings. Cooking is done over open fires with meals of reef fish, yams and bananas as the staples.

Dance is a living art form in Yap with each village presenting dances to the High Chiefs on Yap Day (March 1). Dancers in richly appointed costumes of hibiscus and flowers perform exciting and graphic tales of the culture and history of Yap. Stone money and Shell Money are still used in traditional exchanges and a council of High Chiefs still yields great influence and respect among the people.

The name Palau may be derived from the Palauan word for village, beluu (Pelew). Some trace the name to the Spanish word for mast, palao.

Palau comprises several cultures and languages. Ethnic Palauans predominate, inhabiting the main islands of the archipelago. Descendants of the Carolinean atolls, especially Ulithi, settled on Palau's southern atolls.

Most of Palau's important cultural symbols are derived from its chiefly past, in particular the gable of the community meetinghouse, bai. This impressive thatched building was the center of political, social, and artistic life. Today the decorated bai gable is used in most national and state seals and to decorate Palauan buildings.

Respect toward elders and leaders is still pronounced. In particular the head is considered sacred and should not be touched.

Respect of local traditions and manners are expected and politely observed. Womens' thighs should be covered.

Palau was initially settled more than 4,000 years ago, probably by migrants from what today is Indonesia. British traders became prominent visitors in the 18th century, followed by expanding Spanish influence in the 19th century. Following its defeat in the Spanish-American War, Spain sold Palau and most of the rest of the Caroline Islands to Germany in 1899. Control passed to Japan in 1914 and then to the United States under UN auspices in 1947 as part of the Trust Territory of the Pacific Islands.

Four of the Trust Territory districts formed a single federated Micronesian state in 1979, but this eventually dissolved as the individual districts--long culturally distinct--opted for more locally popular status. Palau approved a new constitution in 1981, subsequently signing a Compact of Free Association with the United States in 1982. After eight referenda and an amendment to the Palauan constitution, the Compact went into effect on October 1, 1994, marking Palau's emergence from trusteeship to independence.

Location and Size

Yap is located in the Western Pacific stretching from 6 to 10 degrees North Latitude and 137 to 148 degrees West Longitude in the Western Caroline Islands. Yap is one of four States that make up the Federated States of Micronesia and is 450 miles southwest of Guam and 360 miles northeast of Palau.

Located in the western Pacific, the Palauan archipelago is the westernmost portion of the Caroline Islands, which are in turn part of the Micronesian geographical subdivision of Oceania. Palau is 722 nautical miles southwest of Guam. Palau's three hundred volcanic and raised coral islands and atolls rise up from the Philippine Plate, with the highest stone outcrops reaching about 720 feet on the largest island, Babel thuap. The islands have a total land area of 191 square miles.

The capital and major population center is Koror, the small set of islands to the south of the main island of Babelthuap. In 2004 the capital will be relocated to Melekeok on Babelthuap.


The population of Micronesia is 104,966 (2016), with 21,501 in Palau, 11,377 in Yap, and an estimated 53,000 in Truk.
