Discover the Forgotten Islands: 10-Day Banda Sea Liveaboard in October 2026
Are you looking for the ultimate bucket-list dive trip? In October 2026, Mikumba Diving is heading to the most remote corners of Indonesia: the Banda Sea.
Known as the “Ring of Fire,” this region is only accessible by liveaboard and offers a window into the ocean as it was centuries ago. From schooling hammerheads to volcanic islands our 10-day expeditions are designed for adventurous divers seeking the extraordinary.
To explore this underwater paradise, Jelajahi Laut is the best way to access the Banda Seas remote pelagic hotspots. Offering expertly guided diving itineraries, Mikumba Diving ensures that your exploration of these incredible waters is both safe and memorable.
Why Dive the Banda Sea in October?
The Banda Sea is Indonesia’s “Hidden Frontier.” Unlike the crowded reefs of Komodo, the Banda Islands (or Spice Islands) offer a raw, deep-sea experience characterised by massive pelagics, crystal-clear water, and the legendary Hammerhead migration.
October is widely considered the peak month for hammerhead shark sightings in the Banda Sea. As the seasons shift, cooler thermoclines rise toward the surface, bringing schools of scalloped hammerheads within recreational diving depths.
- Optimal Conditions: This “shoulder season” offers the calmest seas for crossing the open water between remote atolls.
- Hammerhead Season: Deep-water upwellings at sites like Nil Desperandum and Serua attract massive schools of sharks.
- Incredible Visibility: Expect crystal-clear water, often exceeding 30–40 meters, perfect for wide-angle photography.
Trip Highlights: What to Expect on Your 10-Day Expedition
Our October 2026 itinerary is a carefully curated journey through Indonesia’s most legendary dive sites.
Schooling Hammerheads at the “Forgotten Islands”
We aim to visit remote seamounts like Nil Desperandum. These atolls rise from the deep abyss and are famous for encounters with dozens of hammerhead sharks patrolling the walls.
The Historic Spice Islands (Banda Neira)
Step back in time as we visit the original “Spice Islands.” Between dives on lush coral walls and pinnacles like Batu Kapal, we’ll go ashore to explore Dutch forts and nutmeg plantations that once changed the course of world history.
World-Class Muck Diving in Ambon
Our Banda Sea trips begin or end in Ambon Bay, the undisputed capital of critter diving. Keep your eyes peeled for the Psychedelic Frogfish, Rhinopias, and various rare species of octopus.

Banda Sea Diving FAQ
What experience level is required?
Because of the remote nature and potential for strong currents, we recommend this trip for Advanced Open Water divers with at least 50 logged dives.
How do I get to the Banda Sea?
Primary Hub: Fly into Pattimura Airport (AMQ) in Ambon.
Connecting Flights: Daily flights from Jakarta (CGK) or Makassar (UPG).
Departure: Mikumba Diving trips depart directly from Ambon, saving you 12+ hours of crossing time compared to departures from Flores.
What is the water temperature?
Expect temperatures between 27°C and 29°C, though it can drop to 25°C during hammerhead sightings in the thermoclines. A 3mm or 5mm wetsuit is recommended.
What is the “Hammerhead Window” and why is it so short?
The “Hammerhead Window” refers to the specific weeks in October and November when the trade winds shift and the water temperatures drop. This change in currents creates upwellings that draw scalloped hammerheads from the deep abyss up to depths of 20–30 meters. Outside of this window, the water is often too warm, and the sharks remain in much deeper water, out of reach for recreational divers.
Can I see whales or dolphins in the Banda Sea?
Quite likely! The Banda Sea is a major migration corridor for cetaceans. During our October crossings, it is common to spot pods of Spinner Dolphins, Pilot Whales, and even the occasional Blue Whale or Orca. We keep a keen lookout from the bridge during transit, so keep your binoculars handy on the top deck!
What is the “Ambon Muck Diving” experience like?
Ambon is the perfect bookend to a Banda Sea trip. Unlike the clear blue seamounts, “muck diving” involves exploring black volcanic sand and rubble. It is a treasure hunt for the world’s rarest critters, including the Psychedelic Frogfish, Rhinopias, and Wonderpus. We recommend a high-quality torch and a macro lens to capture these incredible, camouflaged creatures.
