Stunning Sangihe Archipelago
Located about 200 kilometers north of Bangka Island, the islands of Biaro, Tagulandang, Siau, and Mahengetang are part of the stunning Sangihe Archipelago. Our journey begins in Lembeh or Bangka, and we cruise northward towards these remote gems. Due to the often rough seas in this region, this tour is weather and wave dependent, so flexibility is key.
Biaro Island
Biaro is the first island in the chain, easily recognized by a striking 200-meter cliff on its southern coast. The island features a large flooded depression that opens to the sea on the western side, creating a sheltered haven. North of the island, the “Bomb Rock” and “Zaccharias Rock” rise from the depths, showcasing spectacular coral growth. The “Kalokoki” reef, with its gentle slope, is a vibrant underwater landscape, home to an incredible array of soft corals in an explosion of color.
Ruang and Tagulandang Islands
These two islands boast several outstanding dive sites. Off the coast of Ruang, you’ll find two lava flows that attract large schools of fish. The contrast between the black lava rocks and the vivid marine life is a visual marvel. Tagulandang offers more of the same awe-inspiring dive spots, making these islands an unmissable stop on our journey.
Siau Island
At night, the glowing crater of the Karangetang volcano on Siau Island might catch your eye—one of Indonesia’s most active volcanoes. As you dive here, you may even feel a slight rumble as the volcano stirs beneath the surface. The underwater world around Siau is as dynamic as its volcanic activity, with steep underwater slopes, diverse marine life, and the added surprise of a hot spring on the beach near Batu Lehi.
Mahengetang Island
The small but stunning Mahengetang Island features an underwater volcano that plunges from depths of over 500 meters, rising just below the surface. The dramatic underwater topography, combined with crystal-clear waters offering visibility of up to 40 meters, makes the diving here truly exceptional. The remote nature of this island ensures an untouched, pristine environment that’s a true diver’s paradise.
This journey through the Sangihe Archipelago offers a rare opportunity to explore some of Indonesia’s most remote and visually stunning dive sites, each with its own unique underwater landscape and vibrant marine life.
