There are numerous destinations that you can visit almost all the year. But there are some specific seasons that we recommend you to travel. The best time (seasons) to travel in Nepal are Spring (March to May) and Autumn (September to November). Days are warm where the morning and evening are cold in Autumn. In mountain regions, night temperatures go into minus. In Spring, you can see flowers blooming throughout the place you travel or trek. Rhododendron forests can be seen spectacular.
You can travel in the lower altitude region in Winter. The hilly regions where there is no snowfall can be suitable places to travel. Even you can travel during monsoon. If you want to go to trekking, there are rain shadow areas. Mustang region and Dolpo region are the most suitable destination to travel in monsoon. Along with this, day hiking, sightseeing tours and safari tours can be done.
