A visa for Nepal can be obtained on arrival at the Tribhuvan International Airport, Kathmandu and at border entry points in Kakadvitta, Birgunj, Bhairahawa, Nepalgunj, Gaddachowki on the Nepal-India border and Kodari on the Nepal-China border.
Your trek outfitter will normally provide two person waterproof tents, foam mattresses, and all cooking and eating utensils. You will need your own warm clothing, walking shoes, sleeping bag and personal equipment. During the day you will carry your camera, jacket, and water bottle in a rucksack. The rest of your equipment, including your sleeping bag, will be carried by porters.
All hiking will be on trails. You will not need any climbing equipment such as ropes, ice axe, or crampons at any time during the trek. The equipment check list that follows details the equipment you will need for your trek. Most of these items are available for rent or sale in Kathmandu., but all trekking equipment in Nepal is either used equipment that was sold by other trekkers or mountaineering expeditions or locally made reproductions of internationally known brands. The local rucksacks, duffel bags and rain ponchos are inexpensive and will usually stand up to the rigors of a trek or two. Don't be fooled into thinking that you are getting a brand name item, however; most new looking rucksacks available in the bazaar are made in Nepal from imported Korean nylon.
In Kathmandu. casual clothes are the rule, unless you get invited to a formal Nepal government or embassy reception.
