Nepal

Nepal [1] is a landlocked country in Southern Asia, between China and India. It contains eight of the world's 10 highest peaks, including Mount Everest - the world's tallest - on the border with Tibet.

Regions
Nepal is divided into five development regions, from east to west:

Eastern Nepal – Everest region, Arun valley, Kanchenjunga, Ilam.
Central Nepal – Kathmandu and Langtang region.
Western Nepal – Pokhara and the Annapurna region
Mid Western Nepal – Dhaulagiri Himalaya, Dolpa, inner Terai valleys and Jumla.
Far Western Nepal – Mahakali river.
These are further divided into fourteen administrative zones called 'anchal'.

Other regions (most of these are popular names, not official district/region titles): Annapurna, Everest, Kathmandu Valley, Langtang, Mustang, Terai

Other Destinations

Royal Chitwan National Park, to see tigers, rhinos and animals in the Jungle.
Khumbu - at the foot of MT. Everest
Nagarkot - A hill station one hour from Kathmandu offering excellent views of the Himalayan Range.
Daman - a tiny village in the mountains offering panoramic views of the Himalayas - especially stunning at sunrise and sunset.
Dang-Deukhuri - Lowland valleys in western Nepal inhabited by Tharus who have a very distinctive culture.
Dhorpatan - large east-west valley south of the western Dhaulagiri Range. It connects the far western Karnali-Bheri basin that is the birthplace of the Nepali language and probably its rulers to the Gandaki basin that they migrated into before unifying the country. This is also a trekking gateway to the far west, the Dhaulagiri Range, and to Dolpa and other high valleys with Tibetan culture beyond the Dhaulagiris.
Rara Tal (Lake) - large, deep subalpine lake at the foot of Kanjiroba Himalaya, far western Nepal. Another gateway to transhimalayan Humla and Dolpa regions.

Climate
Nepal has a Monsoonal climate with four main seasons - though traditionally a year was categorized into six distinct climate periods: Basanta (spring), Grishma (early summer), Barkha (summer monsoon), Sharad (early autumn), Hemanta (late autumn) and Shishir (winter).

Below is a general guide to conditions at different seasons:

Heavy monsoonal rains from June to September - the rains are generally lighter high in the Himalayas than in Kathmandu, though the mountain peaks are often lost in cloud.
Clear and cool weather from October to December - after the monsoon, there is little dust in the air so this is the best season to 'experience' the mountains.
Cold from January to March, with the temperature in Kathmandu often dropping as low as 0?C at night, with extreme cold at high elevations. It is possible to trek in places like the Everest region during the winter, but it is extremely cold and snow fall may prevent going above 4,000 - 4,500 meters. The Jomosom trek is a reasonable alternative, staying below 3,000 meters with expected minimum temperatures about -10?C and much better chances of avoiding heavy show.
Dry and warm weather from April to June - there is an abundance of blooming flowers in the Himalayas at this time, with rhododendrons, in particular, adding a splash of color to the landscape. Terai temperatures may reach or exceed 40?C while Kathmandu temperatures are about 30?C.
