Visas: A
passport and visa are required. Tourists may purchase two-month, single-entry
visas or two-month, multiple-entry visas upon arrival at Tribhuvan International
Airport in Kathmandu and at the following certain land border points of entry.
Tourists may stay in Nepal no longer than 150 days in any given calendar year. Health risks: Illnesses and injuries suffered while on trek in remote
areas often require evacuation by helicopter to Kathmandu. Travelers should be
aware that emergency services such as evacuations and rescues from remote areas
have been compromised by Maoist attacks on helicopters and airfields and the
destruction of regular phone service in most trekking areas.
