Mahendranagar is the most westerly border crossing into India and offers an interesting back route to Delhi and the hill towns of Uttaranchal. While it’s not somewhere you’ll want to spend any length of time (ie only until your bus is ready to depart), it’s somewhat less chaotic than other India– Nepal border crossings. If you have time here, Mahendranagar provides a useful base to visit Sukla Phanta Wildlife Reserve and surrounding Tharu villages.
Mahendranagar is just south of the Mahendra Hwy, about 5km east of the Indian border. From the Nepali border post at Gaddachauki, it’s about 1km to the Indian border post at Banbassa.
