North Sulawesi's Marine Tourism Expands as Bunaken and Lembeh Draw Global Dive Enthusiasts

MANADO, North Sulawesi - October 1, 2026 - North Sulawesi's marine tourism sector is undergoing a sustained international resurgence, driven by surging arrivals of global scuba diving travelers, wildlife photographers, and marine conservationists. Centered around the iconic vertical coral wall drop-offs of Bunaken National Marine Park and the world-renowned macro muck-diving corridors of the Lembeh Strait, the province is cementing its status as one of the world's most complete and accessible underwater ecosystems.

Tourism data compiled by the North Sulawesi Provincial Tourism Office (Dispar Sulut) in coordination with airport operator Angkasa Pura Indonesia demonstrates a 28 percent year-on-year increase in international dive visitor arrivals through Sam Ratulangi International Airport (MDC) in Manado. The growth has been accelerated by direct international air connections linking Manado with Singapore (via Scoot), Guangzhou, and Tokyo, providing seamless international transit for specialized underwater travelers without passing through domestic hubs in Jakarta or Bali.

Marine biologists and dive resort operators emphasize that North Sulawesi's unique geographical positioning - situated precisely at the northern apex of the Coral Triangle - provides exceptional marine biodiversity encompassing dramatic ocean walls, pristine offshore coral atolls, and volcanic black-sand muck diving.

The complementary dive trinity: Bunaken, Lembeh, and Bangka

North Sulawesi's distinct competitive advantage lies in the diversity of its marine environments situated within short transit distances of Manado:

• Bunaken National Marine Park (Vertical Coral Walls): Renowned for its sheer underwater drop-offs descending hundreds of meters into crystalline oceanic depths. Divers encounter massive sea fans, healthy green sea turtle populations, schooling barracudas, and whitetip reef sharks thriving in warm, high-visibility equatorial currents.
• Lembeh Strait (Global Capital of Macro Muck Diving): Located near the port city of Bitung, Lembeh's volcanic black-sand seabed harbors the highest concentration of rare, cryptic marine species on Earth. Underwater photographers journey across the planet to document blue-ringed octopuses, hairy frogfish, flamboyant cuttlefish, and mimic octopuses foraging in shallow coastal bays.
• Bangka and Gangga Archipelago (Soft Coral Splendor): Positioned at the northern tip of the Minahasa Peninsula, Bangka offers vibrant soft coral gardens, pinnacles, and resident dugong foraging grounds swept by invigorating nutrient currents.

"North Sulawesi offers an underwater range found nowhere else on the planet," said Ketut Suardika, Environmental and Marine Safety Analyst. "A diver can explore dramatic, crystal-clear oceanic drop-offs covered in sea turtles in Bunaken on Monday, and by Tuesday afternoon be photographing the world's rarest macro critters in the dark volcanic sands of Lembeh. That diversity, paired with direct international flights into Manado, makes the province an incomparable marine travel sanctuary."

Community-anchored marine conservation and eco-resort standards

The continued success of North Sulawesi's diving economy is directly intertwined with rigorous marine park governance. The Bunaken National Park Management Advisory Board, in partnership with local fishing communities, enforces strict no-take marine reserves, designated anchor-free mooring buoy networks, and visitor entrance fee systems that directly subsidize village coastal surveillance patrols.

Boutique dive resorts across Bunaken and Lembeh have pioneered sustainable eco-resort practices, eliminating single-use plastics, deploying solar water-heating systems, utilizing biological gray-water reed filtration beds, and mandating reef-safe sunscreen among visiting divers.

Furthermore, local dive centers actively recruit and train young village residents through certified divemaster and naturalist guide apprenticeships, ensuring that local marine stewards command high-wage professional livelihoods within the conservation economy.Travelers organizing a marine expedition to North Sulawesi should note key practical recommendations:

1. Plan a Multi-Center Dive Itinerary: To fully experience the region's marine diversity, split a 7- to 10-day trip between Bunaken (3-4 days of wall diving and reef relaxation) and the Lembeh Strait (3-4 days of dedicated macro critter photography).
2. Fly Direct to Manado (MDC): Utilize direct international flight connections from Singapore or regional East Asian hubs to minimize transit fatigue and eliminate domestic baggage fee complications for heavy scuba gear.
3. Select Accredited Dive Operators: Verify that your chosen dive resort employs licensed dive guides and maintains certified emergency pure oxygen delivery systems on all dive excursion vessels.
4. Account for Dive-to-Fly Surface Intervals: Remember to allow a minimum 24-hour non-flying surface interval after your final scuba dive before boarding flights departing Sam Ratulangi Airport.

Looking ahead

The North Sulawesi Provincial Government is collaborating with maritime authorities to establish formalized marine protected corridors connecting Bunaken with the Bangka archipelago. By maintaining strict carrying capacities and celebrating local marine stewardship, North Sulawesi ensures that its extraordinary underwater treasures remain pristine for future generations of global explorers.
