Mount Kenya - Entry & Health Requirements You can view the British Government's latest advice here. We suggest clients discuss their vaccination requirements with their GP and refer to the TravelHealthProwebsite, 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 Nanyuki Airport but we advise our clients to apply for a Kenyan visa in advance using the new e-visa system on line – this works really well and has significantly reduced waiting times at the airport on arrival. Alternatively, you can apply for a visa from the nearest Kenyan High Commission before you travel. We do not recommend a visa on arrival as this creates unnecessary delays for the whole group.
