Typically most of the information in websites and travel agencies in Nepal recommends Fall and Spring Season are best time to trek in Nepal but Nepal offers some of the best monsoon treks as well that offers very peaceful treks without crowed. It is always while the fall season may have the clearest skies, trekking during the monsoon (from end of May through June, July, August and to early September) has its own rewards. Some treks should be avoided, but for certain areas, it has great time to visit Nepal: the trails are less crowded, the villages are full of life and the valleys are in bloomed and green whereas winter and spring is dry and grey.
The Monson or the summer spans from the beginning of June to the August and sometimes until early September has heavy rainfall in most of parts of Nepal and the roads and trekking paths become wet and muddy and the weather is the most important factor for the trekking so, there are noticeable risk of land slide, flood and trail and road blocks on your trek so, we have selected only few treks for the season where there is less risk of these factors.
Cultural city tours such as Kathmandu tour, Pokhara tour, Lumbini and Safari in Chitwan National park have no issues and they are accessible and doable all around the year and some small treks such as the Chisapani Trek, Nagarkot Trek, Saranngkot Hike, Ghandruk Trek, Ghorepani Trek are possible on monsoon in Nepal. The best selected treks in Monsoon are Upper Mustang, Upper Dolpo, Nar Phu Valley, Lower Mustang, Half part of Annapurna Circuit are Manaslu Circuit which are said to under the rain shadow. Monsoon trek can be best for botanical keens. Wilderenss Excursion offers some of the best following monsoon and summer season treks in 2018 and 2019
