Your Nepal visa is conveniently purchased by you upon arrival at the Kathmandu airport. It is not necessary to purchase a Nepalese visa prior to landing in Nepal. The cost of a 90 day visa is approximately $100 USD & a 30 day visa costs approximately $60. Please bring cash and 2 extra passport-sized photos (extra photos are necessary to obtain the visa in the airport). Please Note: Your passport must be valid for at least 6 months fom the END of the expedition and contain at least 2 blank pages. Please also bring plenty of cash for tips + gratuities, for shopping, drinks, etcetera. You will be paying for your own hotel and meals in Kathmandu . There are good cash/atm machines and traveler's cheques will work, especially in Kathmandu. Members who don't bring enough cash are often found sitting on their hands in a dark and cold hotel room or tent while the rest of the team are out having fun enjoying the night life that is surprisingly exciting and even funny, the sometimes fun pubs and shopping. The "staff tip" will be $75-$100+, £40-£50+, €65-€80+ per foreign trekker. Expect to pay this tip no matter what.
