Celebes Eco Tours

We specialize in the eastern regions of Indonesia — Sulawesi and beyond — famous for their active volcanoes, scenic lakes, lush rainforests, hidden waterfalls, pristine white-sand beaches, fascinating endemic species and warm-hearted locals.

Sulawesi's extraordinary island shape — a geologist's orchid — sits at the meeting point of two eco-regions, giving it some of the highest levels of endemic wildlife on Earth. Our journeys are individual and tailor-made: travel with a minimum of one person, accompanied by your own English-speaking private guide and driver.

Volcanism

Indonesia sits on the Pacific Ring of Fire with 147 active volcanoes. This volcanic energy sculpted Sulawesi's dramatic landscape and created a paradise for hikers and volcano enthusiasts.

Biodiversity

Sulawesi is an evolutionary showcase: the spectral tarsier — one of the world's smallest primates — the crested black macaque, and the ground-nesting maleo. Endemic life found nowhere else on Earth.

Culture

From Toraja's ancestral death rites to Minahasa's rich culinary heritage, every corner of the island offers a different, unforgettable experience.

Underwater World

For divers and snorkelers a hidden paradise awaits: stunning coral walls, sea turtles, reef sharks and the unique critters of the Lembeh Strait.

Hidden Wildlife

The black macaques of Tangkoko, pygmy-sized tarsiers with eyes larger than their brains, and endemic birds — observed responsibly in their natural habitat.

Secret & Hidden Places

Far from the tourist guides: exotic islands, secluded beaches, authentic traditional markets, hidden jungle waterfalls and wildlife in its purest form.

Destinations

Highlights of Sulawesi & Beyond

Researched insights into the natural and cultural wonders that make each stop unforgettable.

Bunaken National Park

Established in 1991, this 890 km² marine park lies at the centre of the Coral Triangle and shelters an extraordinary 390 species of coral and some 2,000 species of fish. Its signature 25–50 metre vertical coral walls drop into depths of up to 1,840 metres, with visibility reaching 35–40 metres. Expect sea turtles, blacktip reef sharks, dugongs, dolphins and — between November and April — passing whales.

Tangkoko Nature Reserve

One of the easiest places in the world to see the spectral tarsier — a nocturnal primate that has remained virtually unchanged for 45 million years. Tangkoko is also home to the critically endangered crested black macaque (yaki), the maleo megapode, hornbills and 328 bird species, 47 of them endemic. Best at dawn and dusk, and just 1.5–2.5 hours from Manado.

Tomohon & the Minahasa Highlands

A cool mountain town surrounded by the twin peaks of Mount Lokon and Mount Mahawu, both active volcanoes you can hike. Wander the famous “extreme market” of Tomohon, explore traditional villages and wooden-house workshops, and admire the vast Lake Tondano — one of Sulawesi's largest lakes — plus hidden waterfalls in the surrounding hills.

Tana Toraja

Known as the “Land of the Heavenly Kings”, Toraja is famed for its Tongkonan ancestral houses with sweeping boat-shaped roofs, carved in red, black and yellow. Its Rambu Solo funeral ceremonies are among the most elaborate in the world — the deceased is considered “sick” until the ritual, which can involve hundreds of guests and buffalo sacrifices. Visit cliff graves, hanging baby graves, tau-tau effigies at Lemo and Kete Kesu, and emerald rice terraces.

Rammang-Rammang

Meaning “clouds or mist” in the Makassar language, this is the second-largest karst cluster on Earth, part of the Maros-Pangkep UNESCO Global Geopark. Limestone towers rise 100 metres above rice fields, and the Pute River — the only route in — is travelled by traditional wooden boat (mallopi). Stop at the stilt-house village of Kampung Berua and explore prehistoric caves whose hand stencils are among the oldest rock art in the world.

Makassar

The bustling capital of South Sulawesi and the gateway to eastern Indonesia. Explore Fort Rotterdam, a 17th-century Dutch fort built on the site of the Gowa-Tallo sultanate's fortress, then watch the famous sunset over Losari Beach promenade. Don't leave without tasting coto makassar and pisang epe from the night stalls.

Lembeh Strait

Widely celebrated as the “Muck Diving Capital of the World” and a mecca for macro photographers. The black volcanic sand between Bitung and Lembeh Island hides an astonishing density of rare critters: more than eight species of frogfish, mimic and blue-ringed octopuses, pygmy seahorses, flamboyant cuttlefish and endless nudibranchs — across over 50 dive sites.

The Moluccas: Ternate, Tidore & Halmahera

The fabled Spice Islands, where cloves, nutmeg and mace once launched European fleets. Explore Ternate's Gamalama volcano and its ancient sultanate, the historic rivals of Tidore, and the wild forests of Halmahera — Indonesia's largest island outside of Sumatra, Java and Borneo — home to the Moluccan cockatoo and endemic birds in Aketajawe-Lolobata National Park.
