|---|---|
| Air Temp | Pleasant 25°C to 30°C all year. |
| Water Temp | Typically 25°C - 30°C. Komodo & Nusa Penida can be colder (down to 16°C!) due to thermoclines. |

Where to Scuba Dive in Indonesia (Top 7)
Indonesia boasts a plethora of remarkable diving destinations. Here are 7 of the top dive locations (in no particular order).
1. Raja Ampat
"The Last Paradise"
Known for its extraordinary marine biodiversity and stunning coral reefs, Raja Ampat is hailed as the most diverse marine environment on our planet. It's a vibrant whirlwind of life, boasting over 75% of the world's coral species.
Ideal for macro enthusiasts and pelagic lovers alike, you can encounter wobbegong sharks, whale sharks, and dense schools of fish. Diving can be intense with vigorous currents. The best time to dive is typically from October to April.
2. Komodo National Park
Our Home & Specialty
The ultimate dream for divers worldwide. While Komodo is renowned for its exhilarating drift dives, the experience goes far beyond that. This UNESCO World Heritage Site offers incredible sites: lunar-like reefs such as Makassar (great for macro), cleaning stations like Manta Point, and impressive pinnacles like Batu Bolong, teeming with fish.
Komodo is characterized by currents. While beginner-friendly sites are available, having current experience enhances the adventure. It's also the only place to see the legendary Komodo Dragons!

3. Bunaken (Sulawesi)
Stunning Walls & Macro
The Bunaken Marine Park is a vibrant haven teeming with life. You can spend an entire dive in one spot, immersed in a spectacle of species. The crystal-clear waters offer excellent visibility for spotting whale sharks, eagle rays, and sharks.
Bunaken is renowned for its steep walls adorned with breathtaking coral. Nearby, the Lembeh Strait is the "muck diving capital of the world," a paradise for macro photographers seeking mimic octopus, rhinopias, and pygmy seahorses.
4. Bali
Wrecks & Mola Mola
Bali remains an underwater paradise. In Amed, you can explore the **USS Liberty Wreck**, a famous WWII wreckage just off the coast. The surrounding region of Tulamben also boasts exceptional muck diving.
To the south, Nusa Penida offers unforgettable encounters with majestic pelagics. Manta Point and Manta Bay practically guarantee sightings. And from July to October, Crystal Bay is the world's best spot to try and see the elusive sunfish (Mola Mola).
5. Gili Islands (Lombok)
Turtles & Relaxed Atmosphere
Famous on Instagram, the Gilis are a backpacker's paradise. While the coral diversity doesn't match Komodo or Raja Ampat, the Gilis offer splendid tropical reef diving with reef sharks, eagle rays, and one of the **highest concentrations of turtles** in the world.
Gili Trawangan is popular for dive courses. We encourage choosing the Gilis mainly for beginner divers who want to take their PADI Open Water Course.
6. Alor
The Hidden Gem
Alor is an undiscovered treasure. While a bit challenging to reach, it offers some of the finest and least crowded diving in the country. Primarily visited by liveaboards, you'll find deserted dive sites, rugged volcanic landscapes, and authentic local culture.
Alor is renowned for exceptional macro, but also for remarkable pelagic encounters: migrating tuna, dolphins, whale sharks, and even a resident population of mola mola. The best diving is from April to October.
We now offer liveaboard trips to Alor! Check our liveaboard itineraries to explore this hidden gem.
7. Lembeh Strait
The "Muck Diving Capital"
A macro photographer's paradise, Lembeh is the best place on earth to capture bizarre critters: frogfish, pipefish, nudibranchs, seahorses, juvenile fish, and blue-ringed octopus.
The dive guides in Lembeh are renowned for their exceptional ability to spot the tiniest critters, catering to photographers who seek to capture every intricate detail.

Tips From People Who Live Here
Helpful tips to keep in mind before embarking on your diving adventure in Indonesia:
- Choose the right destination: If a destination mentions strong currents (like Komodo), be prepared for them to be *really* strong. Dive within your abilities.
- Research your operator: Check accreditation and reviews. Avoid "dive factories" and focus on human-sized, all-in-one dive resorts if you can (like our resort).
- Check rental gear: Prioritize reliable gear and ensure tanks have good air quality.
- Invest in a computer: If you dive frequently, a basic dive computer (around 100 USD) is a worthwhile investment for your personal safety.
- Travel time: Travelling in Indonesia can be time-consuming. Factor this into your dive holiday planning.
