On my forthcoming trip to Yading in June I hope to do a little detour on the final sections. Thanks to the wonders of Google Earth 3D I have discovered this side valley with some alpine lakes that looks like it's worth exploring. So on the final stretch, instead of the usual route heading over the 7th Pass and returning to Chonggu monastery (in blue) I'm planning a little side trip (in red). Of course it's easy to make plans on Google Earth and find that in real life on the ground it is not so do-able. I found this out to my discomfort when i tried descending alone from the Balagong pass above Dimaluo in Yunnan two years ago. Looks straightforward on Google Earth but the reality was very thick bush, followed by a series of farmsteads each guarded by a rabid Tibetan mastiff!
But anyway I shall give it a go. Nothing to lose in trying.
