Nepal is well known as one of the best destination in the world for enjoying the real beauty of nature through trekking. The trail into the interior parts of the country follows ancient foot-trails which meander through scenic river-banks, intricately terraced fields and the forested ridges connecting pictures hamlets and mountain villages. Trekkers can walk along the rough but beautiful trails or virgin tracks in the lap of green and friendly looking hills. The rhododendron-filled, green, dark and deep forests with different seasonal flowers blossoming can catch anyone's eye as can the scattered residential cottages, domestic and forest animals, variety of birds, both Hindus and Buddhist temples, mountains, breath-taking landscape, and above all warm greeting from smiling local people. The highly developed and well-defined trails have been used for centuries. Trekking in Nepal is an all season activity. It is possible at any time of the year depending on where one wishes to go. However, the most popular season are spring (February-May) and autumn (September-November). Even during the monsoon season (June- August), you can trek in the rain- shadow areas north of the Himalaya like Mustang, Upper Manang and Dolpa.
