Scuba Diving in Indonesia

The Republic of Indonesia, the largest island country in the world, is located in Southeast Asia. It consists of thousands of islands of the Malay Archipelago (Indonesian: Kepulauan Melayu). Some of them are large, whilst the others are so tiny that they have no name. The islands are surrounded by the Indian and the Pacific Ocean.
The mountainous landscape makes the Archipelago very attractive, there are over 150 active volcanoes in the country. The coastal and oceanic waters are crystal clear and the underwater world is diverse.
Sulawesi Island is a real attraction for enthusiastic divers. The depths of the local seas, however, are home to many interesting sights, no matter which dive site you choose.
The local waters are a home for several thousands species of fish, there are also sharks, octopuses and whales. They are also a resting place for ancient shipwrecks.

Reasons to Visit

Where to go
in Indonesia?
Indonesia shows off incredibly bright coral reefs. Its waters are part of the legendary Coral Triangle covering the area of 5,7 million sq. km. with the largest variety of underwater biological species in the world. 75% of known species of coral and 3,000 species of fish live there. They include coelacanths (Latin: Coelacanthus) which are considered to be ancestors of land vertebrates. You can still find 380 million-year-old fossils of these fish in Indonesia.
Divers come to Indonesia to visit the Raja Ampat Islands with their picturesque deepwater landscapes created by millions of sea anemones and sea sponges. There are 30 dive sites where you can see turtles, pterois, sea dragons and a wide range of other undersea dwellers. Altogether there are 1508 species of fishes, 537 species of corals and 699 species of molluscs living in the local waters.
Whale sharks live in Indonesia's waters. These terribly looking, 12-meter-long marine creatures are actually harmless and prefer being alone. It is only here that they gather in small groups. While diving in Cenderawasih Bay (Indonesian: Teluk Cenderawasih) you will not just be able take a photo of a whale shark but also touch it. They are not aggressive towards divers.
Indonesia is one of the best places in the world to master your skills in macrodiving. The sun rays reach deep through clear water, so you can see and photograph the tiniest dwellers of the coastal waters, such as molluscs, small seahorses and octopuses, beautiful, many-coloured shrimps and little crabs. Inhabitants of many spots, such as in the Lembeh strait are only found here.
Wreck diving is also popular in Indonesia. The wrecks of 70 ships and 40 planes rest on the bed of the local waters. There are three Republic P-47 Thunderbolt fighter bombers lying at a depth of up to 37 metres, which fell into the water during the Second World War, but are still well preserved. Apart from all this, Idonesia is home to a quarter of the planet's marine plants and animals, all concentrated among weird underwater landscapes.

The Best Dive Sites

The best dive sites are around Sulawesi in Lembeh Strait. Here is where you can see local sea life, take a photo of underwater sheer walls and try wreck diving. Experienced divers recommend exploring several dive sites: Batu Angus, Mawali wreck and Kungkungan Bay.

Health & Safety

Religion has a strong influence on the society in Indonesia, so the crime rate is rather low. The most common crime is stealing things on the beach. Other safety recommendations are typical for coastal areas: keep your valuables in a safe, do not exchange currency with individuals, drink only bottled water.
Unfortunately, healthcare is poorly developed, however, insurance can be useful. The hepatitis vaccination is mandatory everywhere. Dengue fever is widespread.

Dangerous Marine Life

Sharks that live near Indonesian coasts are harmless. The same is not so true about other local deepwater dwellers. Beware of moray eels, which attack people, and poisonous sea snakes — their bites can be lethal.

Eat & Drinks

Rendang is beef stewed in hot sauce with lots of spices. Sweet martabak is a local kind of pancake with different fillings.
Try the most expensive coffee in the world — kopi luwak. It comes from palm civets' love of coffee beans. These animals feast on coffee pulp and later the seeds that are not digested in their stomachs are collected with other fecal matter, washed, dried in the sun and used to produce a drink with a special mild taste.
The remarkable alcohol beverages are 15% strength palm wine called Tuak, light rice wine called Brem and 40% strength Arak made by distilling Tuak.
Tap water is unsafe to drink. Buy bottled water: it is cheap and safe.
