Nepalgunj Airport is located 6 km north of the city centre. The airport was officially named Mahendra Airport after the late King Mahendra, but it is commonly referred to as Ranjha Airport. It operated flights to Kathmandu and to airports in less-developed western districts such as Humla, Dolpa, Jumla, Mugu and Rukum. Nepalgunj airport is the gateway for pilgrims headed to Mt Kailash in Tibet via the Simikot-Hilsa route in Humla district, which, following the 2015 earthquake in Nepal, has become the dominant route for Kailash pilgrimage through Nepal.

Nepalgunj airport is undergoing major redevelopment, and by 2025 its capacity will be increased and it will have world-class facilities inside the airport for customers. The Nepalgunj-Kohalpur highway has been widened to four lanes and is considered one of the best in the country. This has made the journey to Kolhapur easy.

Nepalgunj has bus and minibus services. The country's longest highway, the Mahendra Highway, runs through the town of Kohalpur, 10 kilometers from Nepalgunj city center.

An Indian Railways line reaches Rupaidiha across the border. It involves train changes at Gonda, Bahraich, and Nanpara. For travellers coming in from India it is also possible to take an express train to Lucknow and from there a direct bus to Rupaidiha. Indian and Nepalese nationals may cross the border without restrictions; however, there is a customs checkpoint for goods and third country nationals.
