Yes absolutely. As far as being concerned about theft or robbery, you dont need to worry much but you have to be a little careful. It is equally safe for ladies as it is for gents. You will not have problems with things like eve teasing or gaining unwanted attention. You may wear any sort of clothes of your liking and according to the climate, the society is pretty open minded given that you do not walk in a bikini or half naked. As for weather and climate, the hills are cool , the flat lands humid and hot and the mountains are dry, windy and cold. So, you have to dress accordingly. Nepal is a hospitable country.
The cuisine leaves you savoring the taste forever. People are friendly and very very very warm. You will not have a language problem, almost everyone here understands basic English. If you are concerned about natural disasters, the only thing that might take place is an earthquake and avalanche in the mountains due to it. And all of us know, such things are enevitable. Nepal relies mostly on tourism industry and agriculture for its economy. Hence, tourists are treated well. There will be no discomforts . I hope you found this reply useful.
Safety is a major concern for travelling to almost any hill station, but millions of people still visit them and return with the best of experiences and memories. So if you are careful enough, and vigilant enough, and adventurous enough, Nepal’s terrain will be welcoming you with a promise for your safety.
