Everest BC - Entry Requirements & Health You can view the British Government's latest advice here. We suggest clients discuss their vaccination requirements with their GP and refer to the TravelHealthPro website, which comprises the travel health resources of the National Travel Health Network and Centre (NaTHNaC), which was set up by the Department of Health with the broad aim of Protecting the Health of British Travellers. You can be issued a single-entry tourist visa on arrival at Kathmandu Airport, but we advise our clients to apply for a Nepalese visa in advance using at their nearest Embassy. You can also choose to register using the e-visa system on line – but please note that this still means you receive your visa at the airport in Nepal and will still have to queue. We do not recommend a visa on arrival as this creates unnecessary delays for the whole group.
