Kathmandu	Touring and trekking in Nepal take place throughout the year in Nepal (although some of the more remote areas may be impassable at certain times). There are four distinct seasons in Nepal - each with particular attractions to offer.
Autumn	The Autumn season runs from September to November. In general, the weather is excellent and visitors can enjoy tantalising views of the Himalayan peaks.
Winter	During the Winter season (from December to February) we get occasional snowfalls at higher altitudes so the ideal trekking at this time of year is at lower elevations (generally below 3000 meters).
Spring	From March to May, wild flowers decorate the hillsides. Above 5000 metres, you can walk through fields of flowering rhodedendrons, flourishing in their natural habitat. At lower elevations, the temperatures are temperate and higher up, above 4000 meters, the climate is quite moderate with excellent mountain views.
Summer	The Summer months between June and August mark the monsoon season which usually ends by mid-September, followed by warm and humid weather. The monsoons turn the countryside a lush mid-green and the rivers run fast from the mountains through deep stone gorges. The Summer months are not ideal for trekking but for visitors with an interest in botany or ornithology, the higher valleys and meadows are in full bloom and bursting with rare species.
