March to May is the second-best trekking season in Nepal with a long daylight period. The mid-hill starting from 1,400 to 3,800 metres is generally beautiful with a lot of Rhododendron flowers, magnolia, and full of wild orchids. It is also the best time to enjoy the bird and wildlife in all parts of Nepal and famously in its nature reserves such as Chitwan and Bardia National Parks. It is also the primary mountaineering season, and more than 600 climbers reach Everest Basecamp targeting the summit of Everest. Bright days remain hazy and may expect some thunders and light rains in the lowland and light hailing all around the country. The temperature remains -5 at Everest Basecamp to 32 degrees in the Terai belt.
