The Markha Valley is the most popular trek in Ladakh. It is relatively short, located close to Leh, the walking is mostly below 4000 metres with night stops around 3500 metres and has the best of Ladakh thrown in: Sculpted canyons and fantastic rock formations, medieval villages, Buddhist gompas and snow-peaks. It is now possible to trek the Markha Valley in Ladakh during the summer months July to mid September staying at homestays. I trekked this route in September 2013 with a South Col team and some of the homestays are given here.
