Bunaken & Manado
Bunaken National Marine Park, established in 1991 off Manado in North Sulawesi, protects a cluster of volcanic islands ringed by some of Indonesia's steepest coral walls. The reef flat ends abruptly and the bottom falls away hundreds of meters, so dives here are spent flying along vertical faces stitched with turtles, sea snakes, and clouds of pyramid butterflyfish, with warm clear water and easy logistics from Manado or island resorts.
ここでダイビングする理由
Wall diving is the whole identity of Bunaken, and the walls deliver. Green turtles, some of them huge and completely unbothered, sleep on ledges at Lekuan; banded sea kraits thread the crevices; Napoleon wrasse and the occasional reef shark cruise the blue edge. Currents are usually gentle drifts, which makes the park kind to newer divers, yet the drop-offs, overhangs, and afternoon light keep experienced divers engaged. Fukui's coral slope holds a famous row of giant clams, Manado Tua's points concentrate barracuda and jacks when the tide runs, and the mainland coast adds muck sites and even a wreck for variety. Sulawesi's warm, deep-blue basin gives visibility that regularly stretches past 25 meters in season. Combine it with Lembeh, two hours away, and one trip covers the extremes of Indonesian diving: vertical blue-water walls in the morning, black-sand critters the next day.

The dry season from about March or April through October brings the calm seas and long visibility the park is known for. The northwest monsoon from roughly November to February adds rain, wind chop on the crossings, and reduced clarity, though protected sides of the islands dive year-round.

Green and hawksbill turtles in unusual density, banded sea kraits, Napoleon wrasse, whitetip and blacktip reef sharks, schooling barracuda at the current points, giant clams, pygmy seahorses on the fans, and thick reef-fish life along every wall.
アクセスと宿泊
アクセス: Fly to Manado, then transfer by resort boat from the city waterfront; the crossing to Bunaken island takes under an hour in normal weather. Day-trip diving from Manado hotels is equally practical.
宿泊先: Choose between simple-to-midrange resorts on Bunaken and Siladen islands, which put the walls minutes away, or city comfort in Manado with slightly longer boat runs. Many divers split a North Sulawesi trip between Bunaken and Lembeh.
費用: Diving is inexpensive by international standards, whether from Bunaken island resorts or Manado-based operators running day boats. A national-park entrance fee applies, sold as a tag through operators, and fees support patrols within the park.
ダイビングの合間に: Climb or circumnavigate the Manado Tua volcano cone, snorkel the reef flats, visit Manado's markets and seafood warungs, or day-trip to Tomohon's highlands and the tarsiers of Tangkoko.
スノーケリング: Reef flats atop the walls make Bunaken one of Indonesia's better snorkeling parks; turtles are commonly seen from the surface on the Lekuan side.
安全性と実用情報
危険生物・リスク: Currents at the island points can accelerate without much warning, and the walls drop far past recreational depths, so buoyancy discipline matters. Boat traffic crosses the park; ascend on the reef or with an SMB.
The temptation on a bottomless wall is depth creep; set a floor and watch it. Sea kraits are venomous but placid, and the correct response is simply to give them room.
最寄りの再圧タンク施設: Manado-area hospitals have operated recompression facilities serving the park; status changes over time, and emergencies should be routed through EMS and DAN, with evacuation options confirmed by your operator.
