Whether you are aiming for the base camp of the world’s fifth-highest peak or seeking a classic "off-the-beaten-path" trek, your journey begins on the broad plateau of Tumlingtar.
Traveling by air transforms a grueling 24-hour road trip into a breathtaking 35-minute scenic hop.

For those who prefer tranquil trails over the crowds of Everest, the Makalu Base Camp Trek is unrivaled.
The Route: From Tumlingtar, trekkers drive to Num or Chichila before ascending through lush rhododendron forests and high passes like Shipton La (4,210m).
