Sikkim does not have any airports or railroads because of its rough terrain, however, the first airport of the state is expected to be ready by 2011 in Pakyong, 30 km (19 mi) away from Gangtok. The closest airport, Bagdogra Airport is near the town of Siliguri, West Bengal. The airport is about 124 km away from Gangtok.
A regular Helicopter service run by the Sikkim Helicopter Service, connects Gangtok to Bagdogra; the flight is twenty minutes long, operates only once a day, and can carry 5 people. The cost for the Helicopter ride is Rs. 2200, which is worth it. The beautiful view from the sky makes it worthwhile.
National Highway 31A links Siliguri to Gangtok. Sikkim National Transport runs bus and truck services. Privately-run bus, tourist taxi and jeep services ply throughout Sikkim and also connect it to Siliguri.
