To 'Trek' in the Himalayas means to set off from a given town and to wander through fields and village, along valleys and streams or up mountain slopes to any altitude at one's choice, but usually not above 18000 ft. (5,500m). Trekking- hiking along the trails that form the main links between Nepal's isolated villages and settlements is one the country's main attractions. Until sixties the word of trekking in Nepal was almost unheard of in the rest of the world but many of today's visitors came to Nepal solely to trek.
