Komodo National Park

Best place for a budget dive vacation in Indonesia

In the heart of the Indonesian archipelago lies Komodo National Park, which was designated a UNESCO World Heritage Site in 1991.

While the park is most famous for its resident Komodo dragon – the world’s largest living lizard species – its natural wonders extend far beyond these legendary reptiles.

Underwater, the archipelago provides a habitat for a diverse array of marine life, including manta rays and reef sharks patrolling the reefs.

Scuba divers who venture into Komodo’s subaquatic realm are treated to incredible biodiversity, from brightly-coloured corals to abundant schools of tropical fish.

Diving in Komodo can be divided into three distinct regions – North, Central and South.

The northern region is renowned for its exhilarating drift dives, where strong currents draw in a multitude of pelagic species. Though the currents require a higher level of experience, this is precisely what makes diving in Komodo so electrifying.

Central Komodo is no less captivating, boasting world-class dive sites like Batu Bolong and Manta Point. Here, up to 50 of these majestic creatures can be seen mating and feeding at any one time.

Even the southern region, which experiences cooler water temperatures, offers exceptional critter diving. In these waters, there’s the chance to spot unique species not found in more well-known macro destinations.

Alor

Best place for remote diving in Indonesia

Situated in the Lesser Sunda Islands is the remote island of Alor. It offers an exceptional diving experience for those willing to venture to this relatively untouched corner of the underwater world.

Accessible by liveaboard vessels or just a handful of dive resorts, Alor’s isolation has allowed its marine life to thrive.

Divers are regularly treated to the sight of schools of hammerhead sharks gliding gracefully through the waters. Meanwhile, pods of playful pilot whales and acrobatic dolphins add to the spectacle.

While the strong currents experienced around Alor (particularly from September to November) demand an advanced level of diving experience, there’s are dive sites catering to all skill levels. 

The black sandy sea floor, a result of the island’s volcanic origins, provides the perfect backdrop for muck diving enthusiasts.

Meanwhile, wide-angle photographers revel in the opportunity to capture the grandeur of Alor’s bigger marine inhabitants. Highlights include the schools of barracuda and trevally that congregate in the channels.

Raja Ampat

Best place to dive in Indonesia for biodiversity

Raja Ampat is a breathtakingly beautiful and ecologically rich archipelago located off the northwest coast of West Papua.

Comprising over 1,500 small islands, this tropical paradise is revered by marine biologists as one of the most biodiverse underwater habitats on the planet. It’s home to around 1,500 species of tropical fish and 550 different types of coral. This represents 75% of the world’s known coral varieties.

With its technicolour reefs and teeming schools of fish, Raja Ampat is a diver’s paradise. From sharks, mantas and dugongs to diminutive creatures like the pygmy seahorse, this magnificent archipelago has it all.

Aside from its coral reefs, which remain largely untouched, Raja Ampat boasts underwater caverns and tunnels to explore. It’s no wonder the archipelago is widely regarded as not only one of the best places to dive in Indonesia, but the entire world. 

Raja Ampat lies within the Bird’s Head Seascape, a massive marine protected area. It encompasses not only the “Four Kings” archipelago but also the surrounding regions of Kaimana, Triton Bay and Cenderawasih Bay.

One of the most famous sites, Cape Kri, has recorded 374 fish species in a single dive, a world record that speaks to the site’s incredible richness.

Elsewhere, Batanta’s muck diving sites offer a window into the strange and wonderful world of macro critters. Cenderawasih Bay and Triton Bay are renowned for their incredible encounters with whale sharks. 

In addition to a great choice of liveaboards and eco-friendly dive resorts in Raja Ampat, the archipelago is also home to an abundance of homestays offering budget-friendly accommodation

Banda Sea

Best place for liveaboard diving in Indonesia

The Banda Sea is quickly becoming one of the premier liveaboard diving destinations in Indonesia. It attracts scuba enthusiasts from around the world with its incredible array of marine life and stunning underwater landscapes.

During the peak seasons of September to October and April to May, several Indonesian liveaboard operators make the journey to this remote corner of the archipelago. All are drawn by the promise of world-class diving. 

The Banda Sea is particularly renowned for its exceptional wall dives and abundant macro life. But the real showstoppers are the resident populations of sea snakes at sites like Manuk and Gunung Api islands. These unique serpents, found nowhere else in Southeast Asia, have become a major drawcard.

Additionally, the Banda is also one of the rare spots in Indonesia where divers have a realistic chance of spotting large schools of hammerhead sharks. Big schools of fish, occasional reef sharks and rays, plus some of the most dramatic topography in Indonesia only add to the experience. 

Due to its remote location, the only way to access the Banda Sea’s underwater wonders is by liveaboard.

Many include stops in Ambon Bay, which is a popular destination for muck diving enthusiasts and underwater photographers. This long, protected bay is home to rare and unique marine creatures, including the otherworldly wonderpus and flamboyant cuttlefish.

Reaching this underwater paradise requires a bit of effort. But in our opinion, the journey is well worth it. Wakatobi offers some of the most pristine and vibrant coral reefs found anywhere on the planet. 

While the area has faced some environmental challenges in the past from practices like dynamite fishing, growing conservation efforts have helped to restore the health and vitality of Wakatobi’s reefs.

Now protected within Wakatobi National Park, the area’s 40 or so dive sites are best explored from the luxurious Wakatobi Dive Resort. It boasts a house reef filled with colourful corals, sponges and an incredible diversity of marine life. 

For underwater photographers, Wakatobi is a dream destination and one of the best places to dive in Indonesia. There’s an abundance of unique macro critters like nudibranchs, seahorses and frogfish.

And while large pelagic species may not be as abundant here as in other regions, the biodiversity of Wakatobi’s underwater realm more than makes up for it.

Lembeh Strait

Best place for muck diving in Indonesia

Located in North Sulawesi, Lembeh Strait is rightly known as the “world’s capital for muck diving”. This narrow stretch of water between the islands of Lembeh and Sulawesi is home to an astounding array of small marine creatures.

From the bizarre and whimsical, like the yawning hairy frogfish with its bulging eyes and fleshy appendages, to the alien-like flamboyant cuttlefish with its iridescent displays, the diversity on offer in Lembeh is simply staggering. 

Juvenile fish species like barramundi and pinnate batfish share the reef with predatory snake blennies. At the same time, delicate harlequin shrimp and fascinating mandarin fish put on dazzling shows.

Giant stinging anemones the size of dinner plates provide a dramatic backdrop. It’s also not uncommon to spot camouflaged rhinopias and other cryptic creatures that are nearly impossible to see with the naked eye. 

The sheer number of unique macro subjects that divers can cross off their checklist in Lembeh is mind-boggling.

But Lembeh offers more than just incredible biodiversity. The diving infrastructure is excellent, with photographer-friendly resorts and highly skilled local guides who can lead you to the tiniest critters imaginable.

FAQs about diving in Indonesia

Is Indonesia good for scuba diving?

Indonesia’s reputation as a scuba diving mecca is well-deserved, with this island nation boasting an incredible diversity of marine life.

Encompassing over 17,000 islands, it is home to an astounding array of coral reef ecosystems. There’s everything from hard coral gardens in Raja Ampat to muck diving sites in Lembeh Strait with its mesmerising macro critters. 

Scuba diving in Indonesia offers the change to encounter over 2,000 different types of fish and more than 600 species of corals. That’s three-quarters of the world’s total coral diversity!

Pelagic life is equally impressive, with regular sightings of manta rays, whale sharks and schools of barracuda. 

Catering to this immense popularity, Indonesia has exceptional scuba diving infrastructure. You’ll find luxurious liveaboard vessels (providing access to remote dive sites) and high-end resorts with all the creature comforts you could desire.

Not only is Indonesia an affordable place to learn to dive, but the experiences on offer will impress even seasoned scuba enthusiasts.

Where is best to scuba dive in Indonesia?

Indonesia is a world-renowned scuba diving destination, offering an incredible array of underwater landscapes to explore. Each region has its own highlights, whether its schooling sharks, surreal-looking mola-mola or manta rays flying above cleaning stations. 

One of the best places to dive in Indonesia is Komodo National Park off the island of Flores. Here, there’s the opportunity to spot iconic Komodo dragons on land and come face-to-face with sharks, manta rays and other pelagic species in the nutrient-rich currents. 

Moving north, Bunaken National Park and Lembeh Strait in Sulawesi are renowned for their incredible macro life. They’re among the best places to dive in Indonesia for photographing tiny and bizarre-looking critters.

The remote archipelago of Raja Ampat in West Papua is widely regarded as one of the most biodiverse underwater environments in the world. This means it’s high on the bucket lists of many scuba divers. For coral diversity, Raja is one of the best places to dive in Indonesia.

Lesser known but no less impressive are places like Alor, a remote volcanic island whose cold upwellings attract myriad marine life.

One of the most popular places to dive in Indonesia is Bali. Here, you’ll find vibrant coral reefs and one of the nation’s most fascinating wrecks. That being said, this is also one of the busiest places to dive in the island nation. So you should expect crowded underwater conditions at some of Bali’s best dive sites. 

What are the best months for diving in Indonesia?

The best time to dive in Indonesia varies depending on the specific region and what you hope to see during your underwater adventures. 

In Raja Ampat, the dry season from October through April is generally considered the best time to dive when the weather is more stable and with calmer seas. During this time, visibility is at its best, often exceeding 30 metres (100 feet). 

In Bali, the best conditions tend to occur from March through mid-June and again from September through November. In contrast, the rainy season from December to February can impact visibility.

Meanwhile, July and August can be quite windy, making boat rides to sites like Menjangan Island a bit more turbulent. Over on Nusa Penida, the best time for spotting mola mola (oceanic sunfish) is from July through September. 

Komodo’s prime diving season falls between May and October when dozens of liveaboard vessels ply the islands.

In contrast, Wakatobi is usually at its best during the transition periods at the beginning and end of Komodo’s high season.

The Banda Islands, on the other hand, tend to offer their best diving from March through April and again from September to December.

Do you need a wetsuit to dive in Indonesia?

Water temperatures in Indonesia range from 21°C (70°F) in the Sumba Strait and southern Komodo up to around 30°C (86°F) in the Halmahera Sea and northern Raja Ampat.

While the air temperatures in Indonesia tend to be balmy, you will need a wetsuit, particularly if you are diving multiple times a day.

In the warmer waters of Indonesia’s north, a 3mm wetsuit will usually suffice. However, you may want to bring an extra skin to be on the safe side.

If you’re heading to southern Komodo, the Sumba Strait and Alor, you’ll probably need more protection, particularly at dive sites prone to cold upwellings. Either bring a 3mm wetsuit with layers to put on (and take off) or a 5mm wetsuit with a hood and gloves.
