Hilsa Travel screwed up my flight ticket from Far West Nepal top Kathmandu via Nepalganj completely. I had prepaid the ticket, but they apparently "lost it" and kept me sitting for hours waiting for them to find it as flight time approached. They themselves sat for hours, too, doing nothing. Neither references nor receipts did any impression on them. I eventually got angry (that's for me a first in Nepal) and insisted having them issue me another ticket so I could get out. No avail; only at the last minute they reluctantly followed me to the airport counter and got me aboard a Yeti flight without any papers to show - ticketless travel??? It could be a scam - since the price difference between a Nepali and foreign traveller is huge, for the same seat. So maybe Hilsa Travel and Yeti staff shared the difference?
I got on the flight but did not get around to do things and meet people in Nepalgunj - I spent the whole day waiting for them to wake up. Hilsa Travel agency is NOT recommended for ANY purpose - especially not for issuing tickets. Beware, beware!
Their office is near the airport.
Outbreaks of Japanese Enciphalitis and Dengue fever happens in Nepalganj. Ensure that you are properly vaccinated against j.e. prior to going here. This is a very serious, insect-born disease, but hits only people staying close to poultry, ducks and pigs for a while. These features are ever-present in Nepalgunj. As for dengue, dress up against mosquitoes.
Travelling out of Nepalgunj and on the East-West Highway in this area of Terai you notice all the fixed roads, looks like some huge potholes were just fixed. They are bomb craters, being filled in as they get blown. Especially on raised stretches of road, embankments against flood water, the maoists have this uncanny habit of digging a small horizontal tunnel underneath the road surface and placing pressure or remote controlled bombs. Actually, mostly home-made land mines. The effect on people and vehicles is just terrible, killing upto 40 persons at a time if they feel lucky to have a bus coming... Now, if people tell you that "... today the road is not safe ..." - don't travel, OK?
