Bunaken walls by day, volcano lakes and wildlife treks by dawn
Currently Viewing:
Overview
Bunaken National Park sits just off Manado, North Sulawesi, and is famous for sheer coral walls that start in snorkel depth and drop into deep blue. Base in Manado for the smoothest logistics, food, and day trips, or stay on Bunaken or Siladen to maximize time on the reef. Expect warm water around 27°C, visibility often 15 m to 30 m, and reef life that ranges from turtles and schooling fish to macro surprises tucked into cracks and sponges. The park uses an official ticket system, and conservation fees support management. Add a land day for the Minahasa highlands (Tomohon, Lake Linow) or a dawn wildlife trek in Tangkoko, and this becomes a balanced dive-plus-nature trip that works for divers, snorkelers, and mixed groups.
The signature Bunaken experience is a reef flat you can snorkel, followed by a near-vertical wall that drops fast. Many dives spend time around 5 m to 18 m before following the contour deeper.
Expect hard coral gardens, sponges, and gorgonians, plus turtles, reef sharks, and eagle rays on blue-water edges. Cracks and overhangs are where macro hides: nudibranchs, shrimps, and pygmy seahorses.

Trip callouts
Coral gardens in shallow water, then dramatic walls that can drop well past recreational limits. Great for wide-angle, turtles, and relaxed drifts when the tide is right.
One airport gateway supports multiple micro-destinations: Bunaken day boats, mainland reefs, Minahasa highlands, and Bitung-side wildlife.
Most visitors are comfortable in a 3mm suit year-round, with water commonly around 26°C to 29°C depending on season and depth.
Entrance fees and ticketing support national park management and conservation work. Plan to purchase the official ticket (often handled through operators).
Non-divers can snorkel shallow reefs, visit mangroves, explore volcanic lakes, and do wildlife treks while divers chase wall dives.
scuba
Why Bunaken and Manado for Scuba Diving
Bunaken is North Sulawesi's wall-diving classic: coral gardens in snorkel depth, then dramatic drop-offs that run for kilometers. Base in Manado for smooth logistics and to add day trips beyond the park, or stay on Bunaken or Siladen for short boat rides and early entries. Expect warm water around 27°C, visibility often 15 m to 30 m, and reliable turtle encounters. Most diving is boat-based with tide-driven currents, which makes for easy drifts on calm days and exciting rides when the current picks up.
freedive
Why Bunaken for Freediving
Bunaken is naturally suited to freedivers because the reef flat transitions into a clean wall, so depth is available without long swims. In good conditions, visibility can reach 20 m to 30 m, and water stays warm around 27°C. Many sites are calm enough for snorkel and freedive combos, but current and boat traffic are real considerations. The best freediving here is planned like a dive: go with a local operator, use a float and flag, and pick sheltered walls or shallower reefs when wind or chop builds.
snorkel
Why Bunaken for Snorkeling
Bunaken is one of Indonesia's most satisfying snorkel destinations because the reef starts shallow and stays lively. You can spend hours over coral gardens in 1 m to 6 m and still have a dramatic wall edge nearby. Turtles are a realistic goal on many days, and visibility can be excellent in the drier season. Snorkeling works best with a plan: go early for calmer seas, use a guide on current-prone sites, and keep a safe buffer from boat routes and the wall lip.
topside
What to do when you're not in the water
Manado is more than a dive gateway. It is also the launch point for sunrise wildlife in Tangkoko, cooler volcanic landscapes around Tomohon, and lake and market day trips in the Minahasa highlands. On rest days, you can trade saltwater for crater views, coffee stops, and local food culture. If you are staying on Bunaken or Siladen, topside time is slower: village walks, beach afternoons, and sunset viewpoints, with Manado reached by boat when you want more nightlife or shopping.
