๐ข Terminal Information
Datadawai Airport (WALJ) serves Long Lunuk in Long Pahangai, Mahakam Ulu Regency, East Kalimantan, operating as the sole airport providing air service to this extremely remote region of Indonesian Borneo near the Kapuas River, the longest river in Indonesia. The facility operates without a radio control tower and handles only pioneer flights, with a runway that was lengthened and upgraded by the Indonesian government in 2015 to improve connectivity to this isolated area accessible primarily by river transport.
The airport features basic infrastructure designed for small aircraft operations, with Susi Air providing the primary service offering one daily 12-seat flight to Samarinda, serving as an essential lifeline for the local communities of Mahakam Ulu Regency. The minimal terminal facilities accommodate passengers and basic cargo operations supporting the region's indigenous communities, government services, and essential supply logistics to an area where river and air transport remain the primary means of accessing the outside world.
Positioned in stark contrast to East Kalimantan's extensive coal mining operations that cover 70% of the province, Datadawai Airport serves communities largely removed from the industrial activities dominating neighboring Kutai Kartanegara regency. The facility provides crucial connectivity for medical emergencies, government administration, and cultural preservation efforts in one of Indonesia's most remote regions, where traditional river communities maintain their connection to modern Indonesia through this essential aviation link in the heart of Borneo's pristine interior.
๐ Connection Tips
Datadawai Airport (DTD) is an extremely remote and essential 'pioneer' airstrip located in the Mahakam Ulu Regency of East Kalimantan, Indonesian Borneo. For travelers connecting through DTD, the most important tip is to understand that air travel is the primary lifeline to the outside world. The airport is served by scheduled pioneer flights, typically operated by Susi Air or Smart Aviation, linking the region to Samarinda (AAP). Because these flights use small 12-seat aircraft, seating is extremely limited and should be booked weeks in advance.
A vital connection tip for ground transportation is that the 'connection' continues by water; there are no public taxis or rental cars at the terminal. You must pre-arrange a motorized longboat transfer through a local contact to reach the nearby settlements of Long Pahangai or Long Bagun along the Mahakam River. The airport terminal is a basic, functional building with minimal amenities; there is no public Wi-Fi, food service, or international ATM. It is mandatory to be completely self-sufficient, carrying ample Indonesian Rupiah in cash, as electronic payments are not possible in the deep interior.
The 1,600-meter runway was upgraded in 2015, but flights remain highly sensitive to the tropical rainforest weather; sudden afternoon thunderstorms and low cloud cover can cause multi-day delays. Always build significant flexibility into your return itinerary to Samarinda. Lastly, pack all gear in waterproof, soft-sided bags, as items will be exposed to the elements during the transition between the aircraft and open river boats.

๐ข Terminal Information
Apalapsili Airport (AAS) is a very small, remote airfield located in the mountainous region of Highland Papua, Indonesia. Primarily serving missionary flights, humanitarian aid, and occasional private charters, it acts as a critical lifeline connecting isolated communities with larger towns. The airport's terminal facilities are extremely rudimentary, often consisting of no more than a simple, open-air waiting area or a basic, unstaffed building. The layout is minimalist, with direct access from a small landing strip to the boarding area, which is usually a designated spot on the tarmac.
Security procedures at AAS are minimal, consistent with its classification as a small, remote regional airfield. Formal security checkpoints with advanced screening equipment are not present. Instead, security is typically a matter of visual checks, adherence to light aviation safety protocols, and direct coordination with pilots or humanitarian organizations. There are no significant wait times for any checks. As a domestic airfield, and often a frontier one, there are no immigration or customs facilities on site; these functions would be handled at larger, designated international entry points for any incoming international travelers or cargo.
Amenities at Apalapsili Airport are exceptionally sparse. Passengers should not expect any airline lounges, dedicated dining facilities, or retail shops. Any available provisions would be extremely basic, possibly from a very small local vendor in a nearby village, and travelers are strongly advised to bring all necessary supplies, including food, water, and personal items. Seating in the waiting area is sparse and functional, often outdoors. Accessibility features are rudimentary, primarily consisting of ground-level access only. Travelers requiring assistance must coordinate thoroughly in advance with their charter operator or local community contacts.
๐ Connection Tips
Connecting through Apalapsili Airport requires coordination within Indonesia's highland Papua aviation network, where this remote Yalimo Regency airstrip operates exclusively with charter services from Mission Aviation Fellowship, Associated Mission Aviation, and Susi Air serving isolated communities accessible only by air. Located at 3,883 meters elevation with a single 17/35 runway carved from mountain terrain, the facility serves villages dependent on aviation for essential supplies, medical evacuations, and missionary support, with over 250 indigenous languages spoken across communities relying on these flights for connections to larger regional centers.
Transfers from Apalapsili require pre-arranged ground coordination with local village leaders, missionary organizations, or tour operators, as no commercial transport services exist in this roadless highland region where traditional footpaths and occasional motorbikes provide the only surface mobility options. Connections to Indonesia's commercial aviation network necessitate charter flights to larger airstrips like Wamena Airport or eventually to Jayapura's Sentani Airport for access to domestic routes operated by Garuda Indonesia, Lion Air, and Wings Air. Weather conditions in the central highlands create significant operational challenges, with afternoon cloud build-ups and mountain turbulence frequently closing VFR-only operations without warning.
Missionary aviation operators coordinate most connections through their network of six bases across Papua, with AMA operating under Part 135 charter certificates and MAF maintaining nine aircraft from five strategic locations to serve this region's aviation-dependent communities. Fuel, medical supplies, and passengers must be carefully weight-balanced due to the high-altitude performance limitations of single-engine aircraft typically used for highland operations. Alternative routing during weather closures may require multi-day delays or overland trekking to neighboring airstrips, making flexible scheduling essential for any traveler connecting through this frontier aviation hub serving one of Earth's most isolated populations.
