Nepal basically has two periods of the year that are considered ideal for trekking, the spring season that runs from March through May, and the autumn season that runs from September through November. These two windows of opportunity offer fine weather for trekking, the best conditions and ideal circumstances for making it over the higher passes, and better odds for finding trekking partners.
That isn't to say you can't trek at the other times of year, far from it. For those who prefer a bit of solitude on the popular trails like Annapurna the colder months can be a snow-covered joy to trek through, albeit with better winter weather gear and crampons along to handle the icier conditions. The skies are at their clearest during the winter months. The only real negative is that fewer of the tea houses are open at that time of year.
The monsoon season from June to August is the time of year when remote areas such as Nar Phu, Dolpo and Mustang come into their own as their presence behind the formidable barrier of the Himalayas ensures that each of the respective regions remain largely unaffected by the monsoon rains that drench the rest of the country.
Trekking of course isn't the only string to our bow at Nepal Trekking Experts, and places like Kathmandu, Pokhara, Chitwan, and Lumbini are ideal destinations to visit at just about any time of the year.
