Where Are the Anambas Islands?
The Anambas Islands rest in the Natuna Sea, about 300 km northeast of Singapore. They form part of Indonesia’s Riau Archipelago province, standing out for their transparent waters, lush greenery, and immaculate beaches. While they remain relatively under the radar compared to other Indonesian locales, word is spreading among travelers who crave quieter getaways. Consequently, anyone desiring solitude in an island environment will find these shores irresistible.
Moreover, the Anambas Islands lie geographically closer to Peninsular Malaysia than many parts of Indonesia. This unique position has shaped their cultural blend, as maritime trade routes have historically introduced diverse cultural influences. The local language, cuisine, and traditions reflect this fusion. Traditionally, fishing has been the lifeblood of the communities here, yet tourism is steadily becoming another pillar of the local economy.

Anambas Islands Topography
Similarly, these islands boast striking diversity in their terrain, ranging from lush hilltops to broad sandy stretches. Forested hills cloak many interiors, offering shelter to countless bird species and various small mammals. Rugged cliffs, often overlooking coral-fringed shores, provide spectacular lookout points for those willing to hike. Meanwhile, sandy coves and serene lagoons form gentle transitions between land and sea, where shallow waters teem with marine life.
Consequently, a single island in this archipelago can feel like multiple worlds rolled into one. One minute, you might navigate a rainforest trail teeming with exotic plant life; the next, you could descend to a beach that opens onto a coral reef brimming with colorful fish. Explorers often find hidden gems, such as secluded waterfalls or natural pools, especially on islands like Siantan, Airabu, and Telaga, which are noted for their dramatic landscapes.
Furthermore, Ujung Cliff remains a prime example of how nature sculpts unforgettable vistas. Steep, rocky formations drop dramatically into tranquil waters that shift between sapphire and emerald hues. Adventurers flock here for panoramic views across neighboring islets.
Anambas islands geography supports distinct habitats for it’s often rare tropical flora and fauna. Thick canopy cover in hilly zones regulates local microclimates, while mangroves that line certain shorelines prevent erosion and provide crucial nurseries for fish. Fom granite outcroppings to sandy flats, each type of topography and bathymetry shelters unique species adapted to that environment.
Marine Geography
Anambas islands geography in the waters around Anambas contain staggering beauty and diversity. Extensive coral reefs thrive and are among some of the richest and biodiverse coral reefs in Southeast Asia.
Divers and marine biologists venture out to observe the kaleidoscope of colors beneath the surface, where massive boulder corals coexist with delicate branching varieties. Schools of fish dart among the coral heads, while larger marine animals—such as rays or turtles are often seen.
It is this unique and biodiverse marine geography that caused the government to designate over 1.2 million hectares of Anambas waters a designated marine park.
Lagoons and Bays
The region’s network of shallow lagoons and protective mangroves plays an important role. Mangroves form a buffer between the ocean and the shore, filtering sediments and providing refuge for juvenile marine species. These semi-enclosed waters also often feature seagrasses in their calmer waters which provide both habitat and food for the region’s population of endangered sea turtle . Kayaks or a stand up paddle board (SUP) are a good way to explore these calm areas teeming with crabs, shrimp, small fish and the occasional sea turtle.
Coral Fields
Our snorkeling video, Snorkeling in Serenity, reveals these spectacular coral fields. Local diving operators frequently organise trips to explore various features of the Anambas islands, from reef walls to sandy bottoms inhabited by various species, including seahorses. Visibility remains excellent during the dry season, enabling visitors to photograph vibrant corals and the creatures that dwell among them. For instance, clownfish, parrotfish, and nudibranchs are common sights, adding a variety of colour to almost every dive. Check out the following YouTube links for locations of some more interesting and unique formations and sea life in the Anambas archipelago.
Fishing
Fishing communities depend on these waters for sustenance as well as income. Families in small villages pass down traditional fishing methods like hand-lining or net-casting, mastered through generations. Many communities unite around the harvesting of seafood, which not only feeds local households but also finds its way onto restaurant menus in Tarempa or Letung, or in the case of live finfish, to the wholesale markets in Hong Kong or wider afield. Balancing fishing and conservation remains a delicate task, yet awareness is growing about the importance of healthy reefs and responsible harvests to preserve livelihoods as well as the fragile ecosystem.
Anambas Islands Biodiversity
The Anambas islands geography showcases an impressive variety of flora and fauna—both above and below the waterline. Conservationists delight in spotting parrots, kingfishers, and hawks around forested interiors. Birdsong often echoes at dawn, offering a natural soundtrack to island life. Reptiles such as monitor lizards and geckos also occupy these ecosystems, fulfilling essential roles in controlling insects and small vertebrates.
Nonetheless, the marine realm arguably steals the show. Coral reefs host countless species of fish, from tiny neon damselfish to larger predators like groupers. Sea turtles sometimes nest on quieter beaches, emerging at night to lay eggs in the soft sand. Dugongs, while rare, have been observed in areas of the Anambas, feeding on seagrass in shallow lagoons. Such sightings underscore the ecological significance of the Anambas Islands, which provide critical habitats to it’s endemic species.
Likewise, biodiversity extends to plant life, where coconut palms and pandanus plants abound. These vegetation types support local industries, such as the production of coconut-based products and woven handicrafts. Yet rapid changes—like deforestation or unchecked development—can disrupt these habitats. Invasive species also pose threats to native flora and fauna. Hence, ongoing preservation and monitoring remain essential to ensure the Anambas Islands retain their ecological richness for future generations.
Anambas Islands Conservation
The Bawah Foundation is a poster child of private conservation initiatives for its dedicated conservation work. Their programs include reef surveys, coral replanting, and educational workshops for local residents. Kepri Estates contributes by releasing red coral trout to spawn in protected waters, hopefully boosting fish populations. These concerted efforts form a growing network of initiatives aimed at preserving the archipelago’s fragile equilibrium. Local and international stakeholders are also realising the long-term value of healthy ecosystems for tourism and food security.
Our Article on Anambas Islands Conservation dives into the details of conservations efforts in the province, and this article from United Nations BIOFIN also provides some context on the Marine conservation challenges in remote island: ANAMBAS
Anambas Islands Climate and Weather
The archipelago experiences a characteristically tropical climate, with average temperatures between 26°C and 30°C year-round. The northeast monsoon, typically from November to March, brings heavier rainfall and occasionally rougher seas. Travellers during these months should prepare for intermittent downpours, yet they can also encounter clear days. On the other hand, the southwest monsoon, from April to October, generally brings calmer waters and sunnier skies, making this period ideal for tourism and water activities, with visibility into the calm waters extending down to 25m at times!

Anambas Islands Geological Features
Sedimentary rocks dominate large sections of the islands, the result of layers built up over ages of tectonic shifts, ocean currents, and sediment deposition. In certain areas, you will find striking granite outcrops rising from the coral fields, which exhibit unique sculptural forms where wind and waves have worn away softer materials.
In contrast, cliffs like Ujung Cliff offer high vantage points that reveal the archipelago’s scope. Some local legends connect some cliffs, caves and other features to folklore, claiming they hide spiritual entities or ancient relics. Unverified, but these stories add mystique to the natural wonders that abound in and around Anambas islands’ geography and unique points of interest.
Importantly for resort developers (and their insurance companies!), these stunning geological traits and features don’t come with the geotechnical risks that are normally associated with them. In fact the Anambas archipelago is one of most geologically stable areas in the Asia Pacific region, being remote from the “ring of fire” and tectonic activity that is a feature of most of Indonesia. Our article Anambas islands Geological risks expands on the minimal risks of storms and geotechnical events in this region.
Waterways and Marine Features
The archipelago’s waterways have historically shaped trade and daily life. Natural harbours, bays, and straits facilitated maritime commerce, allowing goods and cultural influences to flow between the Indonesian mainland, Malaysia, and beyond. Consequently, centuries of seafaring have contributed to a local identity steeped in nautical tradition. Whether it’s boat-building or seamanship, these customs endure and support the lifestyle and livelihoods of the local population of Anambas.
Towering hills draped in green rise above turquoise waters, creating a cinematic backdrop for travelers on ferry decks. The view of Telaga peak and it’s occasional shrouding in cloud is a great photographic opportunity on the Letung to Terempa ferry. Local ferries also often double as passenger and cargo vessels, carrying fresh produce, building supplies, and daily essentials between main islands.
Eco-tourism initiatives underscore the importance of maintaining clear navigational routes and pristine water conditions. For example, certain fishing cooperatives limit how and where nets can be cast, to protect reefs and reduce bycatch. Meanwhile, responsible cruising guidelines advise boats to anchor in designated areas, preventing anchor damage on corals. Further efforts focus on promoting waste management strategies, so plastic and other debris do not accumulate in delicate marine habitats.
Likewise, recreational activities thrive in these sheltered waters. Kayaking, stand-up paddleboarding, and sailing find an enthusiastic audience among visitors.
Culture and Lifestyle
Ultimately, the human dimension of the Anambas Islands is just as compelling as their physical beauty. Many locals maintain traditional fishing livelihoods, venturing out at dawn in small wooden boats known as “pompong.” Some families also farm coconuts, breadfruit, and other tropical staples, turning these crops into home-cooked dishes or artisanal products.
Religious beliefs add another layer to the cultural tapestry. The majority of inhabitants follow Islam, and one may hear the call to prayer echo across the water at sunrise and sunset. Small mosques dot the villages, acting as both community centers and places of worship. In addition, there is a minority of Christian and Buddhist communities on certain islands, reflecting the archipelago’s heritage of maritime diversity.
Some villages host lively regattas where colorful sailboats compete for local pride. During significant holidays, residents may stage performances that blend dance, music, and storytelling, echoing ancestral traditions passed down through generations. Guests are usually welcome to join these communal events, which can be a highlight of cultural immersion in the province.
Despite modern influences, islanders tend to value simplicity and close-knit community ties. Many daily activities involve cooperation between families and other village residents. That sense of camaraderie extends to visitors who show genuine interest in local life. Learning a few polite phrases in Bahasa Indonesia or respecting local customs goes a long way. In return, travellers often experience heartfelt hospitality, leaving them with a deeper connection to the places they explore.
