Planning Your First Dive Trip to Indonesia? Start with Maratua Island

Wednesday, 22 Oct 2025

When it comes to scuba diving, Indonesia is truly a world beneath the waves. As part of the Coral Triangle, this archipelago is home to more than 17,000 islands surrounded by the richest marine biodiversity on Earth. From Bali to Raja Ampat, every region offers its own underwater magic. Yet, if you’re planning your very first dive trip to Indonesia, one destination stands out for its pristine reefs, calm atmosphere, and unspoiled charm — Maratua Island.

Tucked away in East Kalimantan, Maratua Island offers everything a diver could dream of: turquoise lagoons, dramatic coral walls, and encounters with turtles, manta rays, and schooling barracudas. For beginners and seasoned divers alike, it’s the perfect balance between adventure and serenity.

Where Is Maratua Island and Why It’s Special

Maratua is part of the Derawan Archipelago, located off the coast of Berau, East Kalimantan. Unlike the bustling dive hubs of Bali or Komodo, Maratua remains peaceful and relatively untouched. Its crescent-shaped lagoon, fringed with palm trees and coral gardens, is a haven for those seeking authentic island life and vibrant marine experiences.

One of the island’s biggest charms is its seclusion. Here, you’ll dive in crystal-clear waters far from crowds, surrounded by nothing but the sound of bubbles and tropical fish gliding by. With easy access via Berau Airport, followed by a scenic boat ride, getting here is part of the adventure.

Diving Highlights in Maratua Island

1. The Channel (Big Fish Country)

This world-famous dive site lives up to its name. The strong current at The Channel attracts big pelagic species like reef sharks, trevallies, and huge schools of barracudas. It’s a thrilling experience for intermediate and advanced divers who crave excitement.

2. Turtle Traffic

For something gentler, head to Turtle Traffic — a favorite among photographers and beginner divers. Here, you’ll find dozens of green turtles cruising gracefully above colorful coral gardens.

3. Kakaban Lake

Just a short boat ride away, Kakaban Island is home to the famous Jellyfish Lake, where you can snorkel among thousands of stingless jellyfish. It’s a surreal, once-in-a-lifetime experience.

4. Sangalaki Island

Another nearby gem, Sangalaki is known for its resident manta rays. Gliding effortlessly through the water, these gentle giants are a sight to behold, especially during feeding time. Book a dive package with Sienna Resort Maratua to explore all these incredible sites with certified dive guides.

Best Time to Dive in Maratua

The best diving season runs from March to October, during the dry months when the sea is calm and visibility can reach up to 30 meters. While diving is possible year-round, the rainy season (November to February) might bring stronger currents and lower visibility — best suited for experienced divers.
