North Sulawesi


North Sulawesi is the long arm of Sulawesi reaching north toward the Philippines, a few degrees above the Equator and in the heart of the Coral Triangle. Manado is the gateway, and the sea off it is the reason to come: the coral walls of Bunaken National Marine Park to the west, and the soft coral pinnacles, black sand slopes and seagrass of Bangka Island at the northern tip.

We keep two stays here, one in each sea. Siladen Resort & Spa sits on a small coral island inside the marine park, its 600 metre white beach facing the volcano of Manado Tua. Coral Eye, on Bangka, began as a marine outpost for biologists and still hosts visiting scientists. They are just over an hour apart by private boat, and our North Sulawesi dive journey joins them, with two dives along the way.

Ashore, the Minahasa highlands rise behind Manado, with volcanoes, the changing colours of Lake Linow and the wooden house builders of Woloan, and to the east the rainforest of Tangkoko, home of the tarsier and the black crested macaque. See our Indonesia guide, Southeast Asia, and the Sportfishing & Adventure and Island Sanctuaries collections.

Elsewhere in the archipelago, the reefs of Moyo Island and the private sailing routes of Indonesia Voyages carry a week on the water further across Indonesia.

Why visit

A reason to make the journey.


  • The walls of Bunaken Coral walls dropping into deep blue water inside a marine park of five islands, created in 1991 and home to more than 390 species of reef-building coral.
  • Pinnacles and macro at Bangka Volcanic pinnacles draped in soft corals and black sand slopes for pygmy seahorses, frogfish and other rare and cryptic creatures.
  • Two seas, one short crossing Siladen and Coral Eye are just over an hour apart by private boat, so one week can hold both, with dives on the way.

When and how

Light, season, and the arrival


Each season keeps its own calendar. We plan the transfer around it.

Best time to visit

When the light is right

North Sulawesi is diveable all year. The dry season, from April to November, brings the calmest seas and the barbecues onto the beach; from December to March there are more showers, and the diving carries on. The water usually sits around 25 to 27°C.

Seasonality

When to go

Air temperatures stay close to 30°C by day all year. April to November is the dry season; the rest of the year brings occasional rain, and the boats still go out. In the water, most divers are comfortable in a 3 mm full wetsuit.

Airport / logistics

Arriving without hurry

Fly to Manado (MDC), served from Singapore, Jakarta, Bali, Makassar, Surabaya and Sorong. Siladen is forty five minutes by car to the harbor and Coral Eye about an hour, each then twenty to thirty minutes by boat. A private boat joins the two in just over an hour, and we time every transfer to your flights.

Traveler questions

Before your North Sulawesi week


  • How do you get to North Sulawesi? Fly to Manado (MDC), with flights from Singapore, Jakarta, Bali and other Indonesian cities. Siladen and Coral Eye are each a drive and a short boat ride from the airport, and we time every transfer to your flights.
  • When is the best time to dive North Sulawesi? The diving is good all year. April to November is the dry season and usually brings the calmest seas; the rest of the year has more showers, and the boats still go out. The water is usually 25 to 27°C.
  • Can you combine Siladen and Coral Eye? Yes. They are just over an hour apart by private boat, and divers can make two dives on the way. Our North Sulawesi dive journey pairs the two: the walls of Bunaken first, then the pinnacles and macro of Bangka.
