Presided over by snow-covered mountains, the Kathmandu Valley is surrounded by verdant agricultural hills scattered with traditional villages and brick houses, rich in ancient holy temples and shrines used by both Buddhists and Hindu worshippers reflecting a great wealth of culture and tradition. Most of the country's ethnic groups are represented in the Valley, particularly in Kathmandu itself, but it is the Newars who are the original inhabitants responsible for development and the splendid art and architecture in the cities.

The Valley is the cultural, political and commercial centre of Nepal and encompasses three cities: Kathmandu the capital; Patan, which has been enveloped by the growing Kathmandu outskirts; and the medieval city of Bhaktapur. For the unprepared visitor, the capital city of Kathmandu can trigger a sensory overload - it is a heaving city of both intriguing and unpleasant smells, incessant noise and pollution, and sights that etch themselves on the memory. Cows wander the streets of the old city, stepping between steaming piles of rubbish and hooting taxis, and narrow alleyways overflow with spices, vegetables and handicraft shops.
