Apart from the monsoonal summer months, when getting around is difficult, you can visit Nepal at any time of the year. If you’re planning to trek, especially at higher altitude, then spring or autumn is the very best time to go to Nepal as the trails will be snow-free, the views clear and the weather warm, especially during the day. If you are planning on walking or touring in the Annapurna foothills or the Kathmandu Valley, then the winter months are also fine to travel, although January and February can be very chilly. For the wildlife-rich parks of Chitwan and Bardia, the optimum time to visit is between October and early March before the heat and humidity gets too high.
