Why Bunaken Belongs on Every Diver's Bucket List
Sitting just off the northern tip of Sulawesi near Manado, Bunaken National Park is a marine wonderland that has captivated divers since it was designated a protected area in 1991. The park encompasses five islands — Bunaken, Manado Tua, Siladen, Mantehage, and Nain — surrounded by some of the richest coral ecosystems on the planet.
The park is famous for its dramatic underwater walls. These near-vertical coral cliffs plunge hundreds of metres into the deep blue, encrusted with sea fans, soft corals, and sponges, and teeming with fish life. On a single dive, it's entirely normal to count dozens of species.
What You'll See Underwater
Bunaken's biodiversity is genuinely extraordinary. The park sits within the Coral Triangle — the global centre of marine biodiversity — and its species list reflects that privileged position.
- Coral species: Over 390 coral species have been recorded, creating a kaleidoscopic backdrop for every dive.
- Fish: Expect encounters with Napoleon wrasse, bumphead parrotfish, hawksbill turtles, white-tip reef sharks, and vast schools of barracuda.
- Macro life: Pygmy seahorses, nudibranchs, and ghost pipefish reward those who slow down and look closely.
- Dolphins and dugongs: Surface sightings of spinner dolphins and occasional dugong are reported around the outer islands.
Top Dive Sites in the Park
- Bunaken Timur (East Bunaken): A classic wall dive with strong currents that attract pelagic species including sharks and large rays.
- Lekuan I, II & III: Three connected wall sites regarded as the park's signature dives — rich, dramatic, and endlessly photogenic.
- Siladen: The small neighbouring island offers calmer conditions and excellent snorkelling, ideal for beginners.
- Manado Tua: An extinct volcano rising steeply from the sea, with diverse habitats from shallow reef to deep wall.
Snorkelling in Bunaken
You don't need to be a certified diver to enjoy Bunaken. The shallow reef tops, particularly around Siladen and the northern shore of Bunaken island itself, offer world-class snorkelling. Visibility is typically excellent — often exceeding 20 metres — and the shallow coral gardens are alive with reef fish and turtles.
Getting to Bunaken
The park is easily accessible from Manado, the capital of North Sulawesi. Public speedboats depart from Manado's old port (Dermaga Manado) most mornings, with the crossing to Bunaken village taking around 30–40 minutes. Alternatively, most dive resorts and guesthouses on the island can arrange private transfers.
Where to Stay
A handful of dive resorts and budget bungalows sit along Bunaken's north coast, ranging from simple beachfront homestays to more comfortable eco-lodges. Staying on the island is strongly recommended — it puts you in the water at sunrise, before day-trippers arrive from Manado, and lets you experience the village's relaxed pace after dark.

Practical Tips
- Bring reef-safe sunscreen — the park takes conservation seriously and standard sunscreens harm coral.
- A marine park fee applies to foreign visitors; check current rates at the Manado port entrance.
- Respect the no-touch, no-collect rules. The park's health depends on it.
- Rent equipment in Manado or bring your own if you're particular about fit — island rental gear varies in quality.
