Kathmandu is situate at 4600ft above the sea level so that’s already a high elevation isn’t it ? Since Mount Everest lies here elevation goes from little bit higher from sea level to highest on earth. The road situation on the remote hilly area is scary and I’ve never tried to drive there but they are best place for hiking and trekking.
I still have to visit basecamp of Mt. Everest and Tilicho lake ( situated at 16237ft) . I hope I can visit them soon.
