This is the earliest day realistically that you can take a return flight. You’re welcome to stay longer however to enjoy the city’s sights. Back in 2015, much of the city, and many architectural treasures were damaged by the earthquake. (Please read the report made by our friend Roland Hunter about the condition of the temples from 2015 for more information.)
We can help you arrange a drop at the airport if in a group, but it is flexible, quick (20 min) and easy just to take any taxi for around $5, which will drop you at ‘departures’ with a smile. Your final Kathmandu experience!
