Ultimate Guide to Bunaken Island!
Imagine stepping into a tropical paradise less than an hour away from Manado—welcome to Bunaken, one of Indonesia’s most stunning marine treasures.
Bunaken National Park spans an impressive 75,265 hectares and is home to five unique islands: Bunaken Island, Manado Tua, Siladen, Mantehage, and Naen. Surrounding these islands lies the famed Bunaken Sea Garden, a spectacular marine sanctuary where crystal-clear waters meet colourful coral reefs.
The park boasts 20 prime dive spots, plunging to depths of up to 1,344 metres. Twelve of these sites circle Bunaken Island itself, drawing divers eager to explore the island’s spectacular underwater scenery. Here, dramatic “hanging walls”—sheer rock faces that rise vertically and curve gracefully—serve as both breathtaking sights and thriving habitats for countless fish species.
Bunaken isn’t just about the ocean; it's a national park that represents a complete tropical ecosystem. Explore lush mangrove forests, seagrass beds, coral reefs, and diverse coastal landscapes. On land, the islands are rich with flora, including palms, sago, woka, silar, and coconut trees. Wildlife lovers can spot unique creatures such as the Sulawesi black macaque, deer, and polecat, while mangrove forests teem with crabs, shrimps, molluscs, and coastal birds, including seagulls, storks, sea doves, and herons.
Activities and Attractions
Bunaken combines soft beaches, lush mangroves, and peaceful trails into a naturally tranquil retreat, making it ideal for both adventure and unwinding in a tropical paradise. This island isn't merely a diver’s paradise—it’s a tropical haven for anyone seeking relaxation and natural beauty.
A haven for diving and snorkelling
Bunaken is dubbed a world-class diving site. Every dive is a kaleidoscope of colour and life, offering a memorable glimpse into the heart of Indonesia’s marine biodiversity. Immerse yourself in the crystal-clear waters of Bunaken National Marine Park. Beneath the waves, 91 species of fish call Bunaken home. Encounter an incredible range of sea creatures, including reef sharks, turtles, manta rays, and macro creatures while you're diving and/or snorkelling.
Popular Sites: Mandolin, Fukui Point, Liang, and Siladen Island.
Island hop your boredom away
Explore neighbouring islands, each with unique attractions. Siladen Island is a quick boat ride from Bunaken, known for pristine beaches and luxury resorts. It's perfect for relaxing, swimming, or snorkelling in calm waters. Another sought-after destination is Naen Island. Tiny in size, most island-hopping tours never skip this in their agendas due to the island's idyllic essence for snorkelling, swimming, and the serene, secluded beaches.
Whereas for more land-filled fun, Manado Tua Island is a volcanic island with a conical peak. It’s great for trekking up to panoramic viewpoints and seeing the old volcanic landscape, plus quiet beaches. Those desiring a less touristy and more natural escape can head to Mantehage Island. Immerse in the local cultures set against the traditional villages and, indeed, more untouched beaches. Mantehage is a wonderful spot to honour less crowded areas.
Marine life observation is like no other
Bunaken’s waters are a haven for biodiversity, perfect for underwater photographers. Even as an admirer of natural beauty, marvelling at the colourful and thriving coral reefs that support an astounding variety of marine life is as magnificent. Spot any sea turtles, dolphins, rays, and more as you explore the stunning underwater landscapes.
Paddle through the mangrove
The island also boasts thriving mangrove ecosystems. The islands’ mangrove forests, rich with Rhizophora, Sonneratia, Lumnitzera, and Bruguiera, create calm waterways teeming with crabs, shrimps, and a variety of coastal birds like herons and seagulls. Paddling or strolling here feels like entering a serene, living laboratory of nature. Check out the eco-tours and kayaking to explore calm channels and spot wildlife in a peaceful setting.
Retreat privately at the beach
The soft, white sandy coves dot Bunaken and Siladen Islands. Bunaken Island’s small beaches offer peaceful spots to sunbathe or swim after a dive, while Siladen Island boasts longer stretches of pristine sand with crystal-clear waters to float in serenity. Unlike crowded tourist beaches, these shores often feel like a private retreat. Swim, snorkel, or simply relax with a book while listening to the gentle waves.
Relaxation is not an understatement
Even if you’re not diving, the gentle rhythm of the island life and the fetching views make it an ideal retreat from the everyday hustle.

Bunaken travel essentials
1. Be environmentally responsible. Bunaken is a protected marine park. Visitors are encouraged to minimise plastic use, follow park regulations, and participate in conservation activities.
2. Book diving in advance! Many of Bunaken’s popular dive sites require permits and experienced guides. Reserving ahead ensures you secure your spot and have access to certified instructors who know the area’s underwater topography.
3. Brace yourself for Limited Wi-Fi, as internet connectivity on the islands can be unreliable. Take this opportunity to unplug, soak in the natural beauty, and fully immerse yourself in the environment.
4. Bring eco-friendly sunscreen since coral reefs are delicate ecosystems. Use reef-safe sunscreen to protect marine life while enjoying time in the sun.
5. Respect marine life, or in other words, admire the rich creatures from a distance. Avoid touching, chasing, or feeding fish, corals, and other reef inhabitants to help preserve the ecosystem.
6. Make sure your vaccinations are up-to-date, and pack a basic first aid kit. Bring any personal medications and stay hydrated, especially when spending long hours in the sun or underwater.
