There's a lot of ground to cover when you talk about diving Indonesia. Indonesia is generally accepted to be the world's best country for sea life; Indonesia has more marine diversity than anywhere on earth. Smack in the middle of the 'Coral Triangle' of diversity that extends from Australia to the Philippines and across to Borneo and into the South Pacific, this country is at the core of the ocean's heart, where the marine variety suggests life in the sea began.
With 20% of the world's coral reefs, over 3,000 different species of fish and 600 coral species, deep water trenches, volcanic sea mounts, World War II wrecks, and an endless variety of macro life, Indonesia has it all. The archipelago reaches Borneo in the West to Papua New Guinea in the East. It has over 17,000 islands and more than 80,000 kilometers of coastline! You can dive Indonesia for years and never do the same itinerary twice – Komodo, Banda Sea, Raja Ampat, Bali, Halmahera, Derawan and Sangalaki ... to name just a few of the remarkable dive destinations within Indonesia.
