Visas: All foreigners (except Indian nationals) require visas, which can be obtained in advance or on arrival. Single-entry tourist visas costing US$30 are issued for up to 60 days and can be extended for a maximum of three months (for an extra US$50). Double and multiple-entry visas are also available. Visas permit travel around the Kathmandu Valley, Pokhara and Chitwan National Park in the Terai. Trekking permits are required if you intend striking out from the main areas; they can be obtained from immigration offices in Kathmandu and Pokhara. National park and conservation fees have risen substantially: it now costs Rs 2000 to enter the Annapurna Conservation area.
