The Aru Islands: The Hidden Paradise That Helped Inspire the Theory of Evolution
There's a cluster of islands at the far eastern edge of Indonesia that almost never shows up on anyone's travel bucket list, despite once being the setting for one of the most consequential journeys in the history of science. It's called the Aru Islands, roughly 95 low-lying islands in Maluku Province, visited in 1857 by British naturalist Alfred Russel Wallace on his search for birds of paradise — a trip that helped shape his thinking on the theory of evolution by natural selection.
Today, nearly 170 years after Wallace's visit, the Aru Islands remain one of the least-visited corners of Indonesia. No luxury resorts, no direct flights from major cities, and most of the outside world couldn't point to it on a map if asked.
Alfred Russel Wallace's Footsteps in Dobo
Wallace arrived in Dobo, the main town of the Aru Islands, on January 8, 1857, after a 30-hour sea crossing by traditional sailing perahu from the Kei Islands. In what would become the classic book "The Malay Archipelago," he described Dobo as a bustling little port, home to around five hundred people from a striking mix of backgrounds — Buginese and Chinese traders, plus visitors from across the Moluccas who came to trade local produce and marine goods.
Dobo was, at the time, the historical trading hub for the Greater Bird of Paradise, a commodity fiercely sought after in European fashion markets. Interestingly, bird-of-paradise skins shipped from Dobo to Europe often arrived with their legs removed, since local hunters cut them off during preservation. This led European scientists to name the species Paradisaea apoda — literally "footless" — and fueled a persistent myth that the bird flew endlessly through the sky without ever touching ground.
Wallace's observations of Aru's biodiversity, including the striking differences in bird and butterfly species compared to western Indonesia, became important field evidence supporting his idea of the Wallace Line — the biogeographic boundary separating Asian and Australian fauna. For anyone interested in the history of science, walking around Dobo today feels like tracing the footsteps of one of biology's genuinely pivotal moments.
Why Aru Is Still So Hidden
Unlike Raja Ampat, which built its reputation years ago, or the Kei Islands, which are slowly gaining recognition, the Aru Islands remain almost entirely untouched by modern tourism. One major reason is accessibility: there are no direct flights from Jakarta or other major cities, and tourism infrastructure is still far more limited here than in other eastern Indonesian destinations.
But that same limitation is exactly what draws in travelers looking for a genuinely authentic experience. Aru offers untouched beaches, sprawling mangrove forests, and biodiversity that remains relatively intact compared to regions that saw tourism arrive earlier.
How to Get to the Aru Islands
- Fly to Ambon: As Maluku's main gateway city, Ambon has regular flights from Jakarta, Makassar, and Surabaya.
- Continue to Dobo: From Ambon, travelers can take a short flight to Dobo Airport (DOB), or opt for a scheduled or chartered boat from Ambon and other Maluku ports for a more immersive sea journey, though it takes considerably longer.
- Island-hopping locally: Once in Dobo, getting to other islands in the Aru group typically means chartering a local motorboat, either directly or through your accommodation.
Since flight and boat schedules to Dobo aren't nearly as frequent as on popular routes, it's strongly advised to book well in advance and reconfirm your schedule before departure, as changes are fairly common on Indonesia's less-traveled eastern routes.
Best Time to Visit
The dry season is the best time to visit Aru, since lower rainfall makes outdoor activities like trekking, snorkeling, and birdwatching considerably more comfortable and safer. Outside this window, wetter weather can make it harder to reach the smaller islands around Dobo, particularly those only accessible by small boat.
Things to Do in the Aru Islands
- Birdwatching: Aru is home to a range of endemic bird species, including several types of birds of paradise still observable in their natural habitat for patient early risers.
- Snorkeling and diving: The coral reefs around Aru have seen relatively little human disturbance, offering an underwater experience that still feels genuinely wild.
- Visiting traditional villages: Many communities in Aru still maintain a way of life deeply rooted in maritime and forest traditions, offering cultural insight rarely found at mainstream destinations.
- Retracing Wallace's footsteps: Walking around Dobo while picturing the port scene Wallace described 170 years ago is a unique experience for anyone interested in natural history and science.
- Exploring the mangrove forests: Aru's extensive mangroves are an important habitat for wildlife and offer a calm route for exploration by small boat.
What to Prepare
Since tourism facilities in Aru remain very limited, careful preparation matters. Accommodation is generally basic guesthouses or homestays in Dobo, not branded hotels. Phone signal and internet access are also very limited outside the main town, so travelers should be ready to go offline for a few days — something that, for many, becomes part of the appeal.
Carrying enough cash is essential, since ATMs and cashless payment are nearly nonexistent once you leave Dobo. Personal medication and a basic first-aid kit are also important to bring along, given how limited medical facilities are on the smaller islands.
Respecting Local Communities and the Environment
As a destination just beginning to appear on travelers' radars, it's important for every visitor to treat local customs and ways of life with respect. Always ask permission before photographing residents or entering areas considered sacred, and use local guides or homestays wherever possible so the economic benefits of tourism actually reach the Aru community itself, rather than outside operators.
Rough Trip Budget
As a rough planning guide, the round-trip Ambon–Dobo flight is typically the single biggest expense of an Aru trip, given how infrequently the route is served. Guesthouses and homestays in Dobo tend to be considerably more affordable than hotels at popular destinations, though options are far more limited, so it's worth confirming or booking through a local contact ahead of arrival. Boat charters for exploring the smaller islands around Dobo vary by distance and duration, and are usually negotiated directly with boat owners or arranged through your accommodation.
Because of limited price competition and fewer options overall, a trip to Aru tends to cost more per day than more established eastern Indonesian destinations like Kei or Ambon — but it's a fair trade for an authenticity that's getting harder to find elsewhere.
Sample Short Itinerary
For a concrete sense of what a trip looks like, here's a sample 5-day Aru Islands itinerary:
- Day 1: Arrive in Ambon, overnight before continuing to Dobo the next day.
- Day 2: Fly to Dobo, settle in and rest, then spend the afternoon walking around town picturing the port scene Wallace described 170 years ago.
- Day 3: Charter a boat to nearby smaller islands for snorkeling and to observe traditional fishing village life.
- Day 4: Explore the mangrove forests and go birdwatching in the early morning, followed by relaxed time on beaches that see almost no visitors.
- Day 5: Return to Ambon, with buffer time built in for the schedule changes fairly common on this route.
This itinerary can easily be extended for travelers wanting to explore more of Aru's roughly 95 islands, each with its own distinct character.
Aru Compared to Other Maluku Destinations
Travelers who've already been to the Kei Islands or even Raja Ampat often ask what sets Aru apart. The answer comes down to how developed each destination is: Kei is starting to have better-organized homestays and is gradually gaining recognition from travel bloggers, while Raja Ampat already has a mature marine tourism industry complete with a paid conservation system. Aru is still well behind both in terms of tourism development.
That's not a drawback — it's the main selling point for a specific kind of traveler: those seeking to experience local life as it actually is, without the layer of commercialization that tends to follow once a destination becomes popular. Aru also carries a unique historical weight that no other Maluku destination can claim — its status as a key research site for Alfred Russel Wallace makes it compelling not just for nature lovers, but for anyone drawn to the history of science.
Aru's Conservation Status
Parts of the Aru Islands have long drawn attention from both international and national conservation organizations, given the region's high biodiversity and a past threat from a large-scale land-clearing plan that emerged some years ago but was successfully blocked thanks to advocacy from local communities and environmental groups. That story has made Aru an important symbol of the fight to protect eastern Indonesia's forests and seas from overexploitation, and it's a good reminder for travelers to visit in ways that support, rather than undermine, those ongoing conservation efforts.
Frequently Asked Questions
Is the Aru Islands suitable for first-time visitors to eastern Indonesia? Aru is better suited to experienced travelers who are comfortable with minimal infrastructure and appreciate slow travel, rather than those seeking resort-level comfort.
How much time should I plan for exploring Aru? At least 4–5 days is recommended, given the relatively long travel time to reach Aru and how much there is to explore once you're there.
Are there official conservation areas open to visitors in Aru? Parts of Aru are important biodiversity conservation areas, so it's best to coordinate with a local guide to understand which areas are open for tourism.
The Aru Islands aren't for everyone — and that's exactly the point. For travelers genuinely looking for something beyond Indonesia's well-worn tourist map, the same islands that once helped inspire one of the greatest scientific theories in human history offer an experience that's hard to match anywhere else that's already found its way onto the map.
