๐ข Terminal Information
Long Apung Airport (LPU), identified by its ICAO code WAQL (formerly WRLP), is a specialized Class III domestic aviation facility located in the Malinau Regency of North Kalimantan, Indonesia. Serving as a critical lifeline for the remote Southern Kayan border region on Borneo Island, the airport operates as a basic landing strip designed to facilitate essential connectivity where land access is extremely difficult. The facility does not possess a traditional commercial terminal complex, instead utilizing a minimalist structure primarily designed for passenger waiting and administrative processing.
The operational infrastructure at Long Apung is characterized by its simplicity and focus on essential 'pioneer' (perintis) flight services. Amenities at the terminal are basic, featuring standard check-in counters and a modest sheltered area where travelers can wait for their scheduled flights. There are no retail shops, diverse dining options, or professional lounges available on-site, and travelers are strongly advised to be fully self-sufficient regarding refreshments and essential supplies. The airport is typically served by regional carriers such as Susi Air and Smart Aviation, utilizing small STOL aircraft suited for the 1,140-meter paved runway.
Ground transportation to and from the LPU terminal is limited and must be pre-arranged with local contacts, as standard taxi or public transit services are not available on-demand in this remote border area. Due to the airport's location in the interior of Borneo and the region's tropical climate, flight operations are restricted to daylight hours and are highly subject to local weather conditions and visibility. Travelers are encouraged to coordinate their arrival well in advance and to confirm flight availability directly with local agents in Samarinda or Tarakan, as schedules for subsidized pioneer flights can be subject to frequent changes. The terminal's straightforward design serves as a functional gateway for the local population and regional workers exploring the remote highlands of North Kalimantan.
๐ Connection Tips
Long Apung Airport (LPU) is an exceptionally remote regional aviation facility in the North Kalimantan province of Indonesia, serving the Southern Kayan region near the border with Malaysia. For international travelers, the journey requires first flying into Jakarta (CGK) or Balikpapan (BPN) and then taking a series of regional flights to reach the interior. Ground transportation is highly informal, consisting primarily of local motorcycles (ojek) or small boats for transit into the village or to nearby remote longhouses. Visitors should be comfortable with very basic conditions and a high level of logistical self-reliance. The Southern Kayan region is world-famous for its unique cultural heritage and spectacular primary rainforest; LPU provides a professional and remarkably direct entry point for those seeking the ultimate authentic Borneo experience.
Because there is no reliable road access to this part of Borneo, the airport provides the only essential link for mail, medical supplies, and passenger travel. Upon arrival at the Long Apung airstrip, expect a minimalist environment. It is mandatory to have a pre-arranged local contact or host meet you at the strip, as on-demand taxi options are non-existent in this part of Borneo. The regional climate is equatorial and humid year-round, with a significant rainy season from December to April that can lead to sudden flight groundings.
Domestic service is limited and primarily provided by regional 'pioneer' carriers like Susi Air, which operate small turboprop aircraft to the major hubs at Samarinda (SRI) and Tarakan (TRK). The airport features a single unpaved grass runway and lacks a formal terminal building, commercial dining, or retail services. Travelers should be entirely self-sufficient, bringing their own food, water, and essential medical supplies for their stay. If you are connecting from Long Apung back to a long-haul jet service in Balikpapan, it is strongly advised to allow at least a 48-hour buffer to account for potential weather disruptions.

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.
