Safety and security
It is highly recommended that you have health insurance while traveling Nepal and some trekking agencies do not take people who don't have proper insurance. Inside major cities like Kathmandu, Pokhara, and Biratnagar there are normal toilets and in the rural parts, there are squat toilets. These parts don't have toilet paper so be sure to carry one. In the major cities, the health facilities are awesome but as you travel away from them, they are still available but not as frequent as in the cities. If you are facing problems, be sure to get properly diagnosed by a doctor. In some cases, you need to take a vaccine before traveling. There aren't any sort of harmful crimes prevailing here, but, don’t talk to any sort of strangers, give money to any sort of beggars, and pay careful attention to your belongings. On a normal day, be sure to carry basic necessities like sunscreen, Vaseline, and lip balm. Also, the water bottles sold by local vendors might not always be of excellent quality. So, having a portable water purifier can go a long way to have a safe trip.
