This pass between Lobuche and Gokyo is locally known as ”Tso La” which literally means, the lake pass. Don’t get excited with the name as there is no lake in the top of the pass, however, the foothill is surrounded by small glacial lakes.
Cho La pass is one of the most popular passes in the region as it connects both Gokyo and Upper Khumbu sides of Everest as well as had a great role in medieval Indo-Tibet trade.
Also, the crossing is quite popular as you will be traversing through glaciers (two biggest ones of Himalayas). The experience truly is adventurous, and as always, be careful about the journey in a bad weather day. It is not recommended.
