May is a good month for the Har Ki Dun Trek if you want green valleys, mountain views, and a chance to see snow on the higher slopes. Days are often pleasant for walking, but nights can be very cold at higher camps. In the first week of May, some parts of the trail may still have snow. The trek usually takes 7 days and covers around 40–45 km, depending on the route. The highest point is about 11,600 ft. Along the way, you pass through forests, old mountain villages, and open meadows.
May is a good choice if you want to see the valley in spring. However, you must pack warm clothes and be ready for rain, cold nights, and changes in trail conditions.
