๐ข Terminal Information
Simikot Airport (IMK) is a high-altitude mountain airstrip situated at approximately 9,200 feet (2,800 meters) in the Humla District of Nepal. It serves as a critical transportation link for the Karnali Zone, providing the only practical access for the local population and for pilgrims and trekkers heading toward Mount Kailash and Lake Mansarovar in Tibet. The airport features a single, relatively short asphalt runway and a modest passenger terminal facility.
The terminal at Simikot is designed for small, short-takeoff-and-landing (STOL) aircraft such as the Twin Otter or Dornier. The infrastructure is basic, consisting of a simple check-in area and a waiting hall for departing passengers. Because the district lacks road connectivity, almost all supplies, medical goods, and travelers must pass through this facility, which often results in a busy and active environment despite the lack of modern automation.
Flight operations at Simikot are strictly regulated by the weather, with most activities occurring in the early morning before the onset of strong mountain winds. The terminal offers very few amenities, and passengers should expect a rustic experience without Wi-Fi or formal dining options. Instead, the terminal provides a functional and vital service, acting as a gateway to some of the most remote and beautiful landscapes in the Himalayas.
๐ Connection Tips
Connecting through Simikot Airport (IMK) is an adventure in itself, primarily because it serves as the essential jumping-off point for those traveling into the Humla District and across the border into Tibet. There are no formal air-to-air transfer facilities or secure transit areas within the terminal. All passengers arriving from Nepalgunj or Kathmandu must disembark, collect their baggage manually, and clear the terminal area. If your journey involves a transfer from a fixed-wing aircraft to a helicopter for the final leg to Hilsa, it is crucial to allow for a significant bufferโoften an entire dayโdue to the frequent and unpredictable weather-related delays.
Simikot is one of Nepal's most weather-sensitive airports, and early morning flights are the only ones you should rely on. Strong afternoon winds frequently lead to the closure of the airstrip, and mountain fog can ground flights for several days at a time. It is highly recommended to maintain close contact with your trekking agency or airline representative, as flight schedules are often managed informally on the ground. There is no digital flight tracking system available to the public, so updates are generally provided through local staff and pilot radio communications.
While waiting at the terminal or in the town of Simikot, you will find only basic tea houses and small shops offering simple snacks. There are no premium lounges or extensive dining facilities. It is essential to carry your own supply of high-energy foods and adequate water. Given the high altitude of the airport, you should also be mindful of altitude sickness and ensure you have warm clothing readily available, as temperatures can drop suddenly. Always keep your travel permits and ID in a waterproof folder, as the mountain weather can change without warning.

๐ข Terminal Information
Biratnagar Airport (BIR) is a critical aviation gateway serving the Morang District and the wider eastern region of Nepal. As the country's second or third busiest domestic airport, it plays a vital role in connecting the industrial hub of Biratnagar with the national capital, Kathmandu, and other regional centers. The airport is currently in the final stages of a transformative expansion, with a massive new terminal building spanning over 16,000 square meters nearing completion. This state-of-the-art facility is projected to become the largest domestic terminal in Nepal, designed to handle up to 550 passengers simultaneously and featuring 17 modern check-in counters.
The current operational terminal, while more modest, provides essential services including night flight capabilities and an on-site aviation fuel depot, making it a key logistical node for eastern Nepal. The ongoing modernization project includes provisions for future regional international flights, with dedicated sections for customs, immigration, and quarantine services already integrated into the new design. The airfield features a 1,500-meter asphalt runway, which is slated for extension to 1,770 meters to accommodate larger aircraft and improve safety margins for the robust schedule of daily flights operated by major carriers such as Buddha Air and Yeti Airlines.
Amenities at the airport are well-developed for its regional status, including multiple cafes and snack bars serving local and international refreshments, specialized retail kiosks for souvenirs, and essential banking services with on-site ATMs. The terminal offers comfortable waiting lounges, free baggage trolleys, and comprehensive information desks to assist travelers. Connectivity to the Biratnagar city center is excellent, with the airport located just 3 to 5 kilometers away. Ground transportation is readily available through local taxi services, rickshaws, and pre-arranged hotel shuttles, providing quick 15-minute links to the city's commercial areas and the nearby Indian border at Jogbani.
๐ Connection Tips
Connecting at Biratnagar Airport (BIR) is a unique experience as it undergoes a massive transition from a traditional regional strip to Nepal's largest domestic aviation hub. While the airport currently operates from a modest terminal, it is a critical node for travelers heading to the industrial heart of the Morang District or those transferring to Short Take-Off and Landing (STOL) flights for the hilly eastern districts like Tumlingtar, Bhojpur, and Taplejung. Most connections at BIR are 'self-transfers,' meaning you must collect your bags from the simple ground-floor carousel and re-check them at the counters of your onward airline, typically Buddha Air or Yeti Airlines.
A significant advantage of BIR is its night-flight capability, allowing for late-evening departures and arrivals which are rare in Nepalโs domestic network. However, travelers must be acutely aware of the 'Terai fog' during the winter months (December to January). Morning flights are frequently delayed or cancelled due to low visibility; for the most reliable connections during this season, it is advisable to book afternoon or evening slots. If you are using Biratnagar as a stepping stone to an international departure from Kathmandu, seasoned travelers recommend a buffer of at least 7 to 8 hours to account for weather disruptions or Air Traffic Control holds in the Kathmandu valley.
The airport is currently in the final stages of opening a state-of-the-art 16,000-square-meter terminal building. Until this is fully operational, expect the current facility to be crowded during peak hours. Outside the terminal, taxis and e-rickshaws are plentiful for the quick 5km trip into Biratnagar city. There are no luggage lockers available, so plan to keep your belongings with you during any short layovers.
