All provinces of Nepal except Province No. 2 have difficult geographic features. Only three districts out of fourteen of Province No. 1 falls in Terai and one district falls in inner Terai. Elevation from lowest point of Nepal, Kechana (70 m above sea level) to the highest point of world, Everest (8848 m above sea level) lies in this province, so maintaining consistent road network is one of the most challenging. Despite of those challenges, all districts are connected via road networks. Air services are available. Rail services are under construction.
