Long Mesangat – Home of the Rare False Gharial and East Kalimantan's Precious Wetland

Long Mesangat is one of East Kalimantan's most ecologically extraordinary districts – home to Danau Mesangat (Mesangat Lake), a complex of shallow peat swamp lakes and seasonally flooded forest that represents the most significant known habitat for the false gharial crocodile (Tomistoma schlegelii) in all of Indonesia. The false gharial is one of the world's most endangered reptiles – a slender-snouted crocodilian that was once widespread across Borneo's river systems but has been reduced to a handful of populations as its peat swamp habitat has been drained and converted across the island. The Danau Mesangat wetland complex is protected in part by its relative inaccessibility, and survey work by conservation organisations has documented a population of false gharials that is significant for the global conservation of the species. The district also provides habitat for sun bears, proboscis monkeys, various river otter species, and an exceptional diversity of wetland birds that use the lake and its surrounding peat swamp forest.

Tourism & Attractions

Wildlife watching at Danau Mesangat is among the most specialised and rewarding ecotourism experiences available in Indonesian Borneo. The false gharial is rarely seen by visitors – patient observation from boats in the early morning and evening, in the sections of the lake where the animals are known to bask, offers the best sighting opportunities. Proboscis monkeys are far more reliably visible, gathering along the lake margins in the late afternoon before crossing the water channels to their overnight roosting trees. The wetland bird diversity is exceptional – various species of stork, heron, kingfisher, eagle and specialist wetland birds that require intact peat swamp habitat to survive. The peat swamp forest itself, with its distinctive flora of pitcher plants, sphagnum moss and tall swamp trees, has a unique character quite different from the dipterocarp forest that dominates much of Borneo.

Real Estate Market

Long Mesangat has essentially no conventional real estate market – the ecological sensitivity of the wetland and the active conservation programmes in the area have largely prevented the agricultural and industrial development that characterises neighbouring districts. The conservation value of the intact peat swamp is increasingly being recognised through formal conservation finance mechanisms. REDD+ carbon credits and biodiversity credits from the peat swamp ecosystem have been discussed in conservation planning contexts. Any development in or near the wetland must comply with Indonesia's peat land protection regulations, which prohibit drainage and cultivation of deep peat soils.

Rental & Investment Outlook

Conservation finance represents the primary investment opportunity – carbon credits from the peat swamp ecosystem (which stores enormous quantities of carbon in its deep organic soils) and biodiversity credits from the false gharial and other protected species habitat. Small-scale ecotourism – a low-impact research lodge or guided wildlife observation programme serving conservation scientists and specialist wildlife tourists – would generate income compatible with the conservation objectives of the site. International conservation organisations (WWF, WCS, Frankfurt Zoological Society) have all expressed interest in the Mesangat wetland as a conservation investment site. Community partnerships with the Long Mesangat community are essential for any intervention in this ecologically and culturally sensitive area.

Practical Tips

Long Mesangat is among the most remote districts in Kutai Timur – access requires a long journey from Sangatta by road and boat, with journey times of 5–8 hours depending on conditions. Contact conservation organisations working in the area for guidance on responsible access and current site conditions. The peat swamp terrain is extremely challenging to navigate on foot – all exploration should be done by boat with experienced local guides who know the lake channels. The false gharial is highly sensitive to disturbance; maintain respectful distances and follow guide instructions precisely. The best seasons for lake visits are June–September when water levels are lower and wildlife concentrates near the remaining water. Malaria prophylaxis is strongly recommended for the peat swamp interior.

Kutai Timur – Kutai National Park and Lowland Rainforests in East Kalimantan

Kutai Timur Regency lies in the eastern part of East Kalimantan province, on the Makassar Strait coast. Its capital is Sangatta. The region is home to Kutai National Park – East Kalimantan’s largest protected lowland rainforest area – and is also one of Indonesia’s biggest coal mining centres.

Attractions and Activities

Kutai National Park (198,000 hectares) is one of Borneo’s oldest protected areas: lowland dipterocarp forest, orangutans, proboscis monkeys and Borneo-endemic wildlife. The Sangkima ecological trail features giant tropical trees (strangler figs) and a mangrove boardwalk. Prevab research station is excellent for orangutan observation. Kaubun Beach (Pantai Kaubun) is a turtle nesting area on the northern coast.

Culture and Cuisine

Kutai Timur’s population is mixed: Dayak, Kutai Malay, Bugis and Javanese transmigrants. Coal mining dominates the economy, but ecotourism is developing around the national park. Cuisine is Kalimantanese: udang galah (river prawn), amplang, nasi kuning and local seafood dishes.

Public Safety

Kutai Timur is generally safe. Heavy vehicle traffic exists around mining areas. A guide is mandatory in the national park. Medical care: mining hospital in Sangatta; Samarinda (approx. 4 hours) has more complete facilities.

Practical Information

From Samarinda, approximately 4 hours north-east by car. From Balikpapan, approximately 5 hours. Sangatta Airport operates limited flights. The best time to visit is May to September. Accommodation: hotels in Sangatta town.

East Kalimantan is Borneo's largest province, where the Derawan Islands' marine paradise, the Mahakam River's culture, and the new capital Nusantara converge. The region is world-famous for diving, sea turtles, and the stingless jellyfish lake.

Where is East Kalimantan?

The province is located on Borneo's eastern coast, along the Celebes Sea. Balikpapan and Samarinda are the main cities, both with international airports. Indonesia's planned new capital, Nusantara, is currently under construction in the province's northern part.

What to See?

1. Derawan Islands – Marine Paradise

The Derawan Islands are an archipelago with crystal-clear waters where sea turtles, manta rays, and sponges await. Kakaban Island's stingless jellyfish lake is unique: the jellyfish don't sting, and you can swim among them. Sangalaki Island is a nesting site for manta rays and sea turtles.

2. Kutai National Park

Kutai National Park is one of Borneo's oldest protected areas. Orangutans, Bornean elephants, and rare bird species live here. The park spans rainforests around Sangatta.

3. Mahakam River

Indonesia's third-longest river is the stage for Dayak and Banjar culture. River cruises offer sightings of dolphins, traditional villages, and floating markets. Tenggarong and Kutai Kartanegara are historically significant towns along the river.

4. Nusantara – The New Capital

Nusantara, Indonesia's planned new capital, is currently under construction in northern East Kalimantan. The implementation is in progress, and the region is becoming an increasingly important tourism and economic hub.

5. Balikpapan and Samarinda

Balikpapan is the oil industry center, but Kumala Beach and local gastronomy are also attractive. Samarinda is the gateway to the Mahakam River, from where river excursions depart.

When to Visit?

March–October is the dry season, ideal for diving at the Derawan Islands and river tours. The jellyfish lake is visitable year-round.

How Long to Stay?

5–7 days recommended:

• 2–3 days: Derawan Islands, diving, jellyfish lake
• 1–2 days: Mahakam River cruise
• 1 day: Kutai National Park
• 1 day: Balikpapan or Samarinda
