Indonesia is comprised of over 17,000 islands, of which only 6,000 are inhabited, making it the world's largest archipelago. Lying in the heart of the coral triangle and creating a seam between the two most productive tropical Oceans, the Pacific and Indian, Indonesia is a divers paradise.
The variety and abundance of island shapes and sizes create habitat for reefs in many different varieties; from mangroves to deep walls, and black sand volcanic bubbles, the entire archipelago teems with life. As it covers such a huge area (1,919,440 km2) and it is so sparsely populated, it is an ideal destination for liveaboard diving trips.
There is undoubtedly more concentrated abundance in places like Raja Ampat, located off of Indonesian Papua and considered the world's most bio-diverse region, Bali, Sulawesi, and Komodo. Tidal fluctuations between the Pacific and Indian Oceans create currents which draw nutrient rich waters from the depths to the shallow, where it acts as a catalyst for sustaining such high diversity and abundance.
Above water the country is a combination of many volcanic, some active some dormant, regions. The landscape is stunning and lush, covered in tropical vegetation and teeming with different species of animals. As Indonesia also connects the contents of Asia and Australia, it shares species from both. This becomes evident as you move from the west, where it is mostly Asian, to the east, where it becomes mostly Australian. The famous Wallace Line divides Bali from Lombok and is a distinction of just how special the area really is.
Diving mostly involves current and can be challenging, but extremely rewarding. It is amongst, if not, the best tropical diving destination in the world. Where anything from hammerheads, mantas and mola-mola can be seen in the same day as rhinopias, pygmy seahorses and rare un-described nudibranches.
Because the equator runs through northern Indonesia, the water temperatures tend to range in a comfortable 26°-28° degrees Celsius, and visibility can range from 10-30+ meters, depending on local conditions and the reef systems diving on. Weather is moderate year round, with the southern islands experiencing rain from January to March, and the northern islands from June to September. In all destinations there are liveaboards running trips year round.
