The waters of Indonesia are at the epicenter of marine biodiversity, and the numbers are impressive: a 2,500-mile swath of islands and coral reefs home to more than 2,000 species of fish, 500-plus varieties of hard and soft coral and thousands of enigmatic invertebrates. From the weird and wonderful critters in Lembeh Strait to the graceful mantas and coral spires of Komodo and the dramatic walls of Wakatobi, the diving in Indonesia is some of the best in the world. Few places on the planet are as varied, and as packed with interesting and unusual marine life such as wunderpus, mimic octopus, flamboyant cuttlefish, pygmy seahorses, harlequin shrimp and ornate ghost pipefish.

Diving in Indonesia

Straddling the Equator and stretching more than 3,200 miles from east to west, Indonesia is a country of more than 17,500 islands. From this vast array of coastlines, a select number of areas have emerged as favorites among divers. This area, east of Malaysia and west of Papua New Guinea, is at the epicenter of our planet's marine biodiversity. From the weird and wonderful critters in Lembeh Strait to the graceful mantas and incredible coral gardens of Komodo, the diving in Indonesia is some of the best in the world. Few places on the planet are as varied and give you the opportunity to see more diverse underwater flora and fauna including more than 2,000 species of fish, from car-sized whale sharks to pygmy sea horses smaller than a grain of rice. There are reef slopes, drop offs, plateaus, caves, wrecks and muck diving sites. Northern Sulawesi is Indonesia’s muck diving capital, with Lembeh the reining king for weird and wonderful critters. If you are looking for subjects like the endemic Banggai cardinalfish to the amazing mimic octopus and wunderpus this is the place to find them. And the cast of critters does not end there, Lembeh also features lacy scorpionfish, flamboyant cuttlefish, harlequin shrimp, as well as some of the wildest species of nudibranchs known to man. In Southern Sulawesi, the focus shifts to reefs, with the Wakatobi region offering some of the finest coral formations in the Indonesia. Here, vertical escarpments that begin their drop mere feet from the surface straight down hundreds of feet into the depths. To the east, off the tip of West Papua the tip of the islands of Raja Ampat offer stunning topside profiles, and near-pristine reefs that harbor the world's greatest number of fish species in one location. Divers often tally more than 200 species on a single dive. Some live aboard itineraries also venture into Triton Bay, which is known for extensive soft coral coverage, vast forests of black coral, big schools of fish, epaulette sharks, pilot whales and more. Recently, divers have also discovered Cenderawasih Bay, where whale sharks congregate. Indonesia's other prime liveaboard destination is the Komodo region, where divers can choose between calm reefs and coral-covered pinnacles that attract large schools of fish, with a good chance of mantas and sharks, plus land visits to see Komodo dragons. Other liveaboard itineraries may take in remote sites in the Banda Islands, known for dense fish populations and pelagic sightings, and Alor for macro life and benthic diversity. Because most Indonesian dive trips begin and end at Bali, many travelers add a few days to their itinerary to explore the reefs and walls around the island. A favorite dive is the USS Liberty Wreck, which has the distinction of being the only ship in the world sunk by a lava flow.

Culture and Customs

Indonesia is a nation of islands, and of blended cultures. Centuries of maritime trade have spread influences of Indian and the Far East, but individual island groups have also developed their own traditions and languages. The region is home to more that 300 distinct native ethnic groups, and 742 different languages and dialects. One trait that is common to all of these disparate communities is a tradition of hospitality and acceptance for travelers. The attentive service lavished on guests of resorts and liveaboards is not an affectation, but an integral element of a national psyche that take pride in playing the welcoming host. Equally apparent is a sense of tolerance, which allows the traditions of Hinduism, Buddhism, Confucianism, Islam and Christianity to coexist. Indonesia is also a land of contrasts. Jakarta's steel and glass towers soar to heights of more than 1,000 feet in one of the most modern commercial centers in the region. A thousand miles away, islanders living in traditional villages still observe local traditions of ancestor worship and animism such as Kebatinan. And then there is the food. Indonesian cuisines are among the most vibrant and flavorful in the world, mixing intense spices and subtle overtones that draw from the culinary traditions of India, Holland, the Middle East, China, southeast Asia, Polynesia and Melanesia. Equally savory is the lively street food scene, where the rich aromas of bakso or gila fill the air.
