Best time to visit: Generally October–November and March–April are considered the best times to visit, offering clear skies and pleasant temperatures, especially for trekking. Winter (December–February) can be cold in the mountains, and the monsoon (June–September) brings heavy rain, leeches on trails, and reduced visibility, though it can be greener and less crowded.. Longer daylight hours during this period help travelers recover from jetlag more quickly, as natural light is the strongest zeitgeber (time cue) for resetting your circadian rhythm.
