Few decades ago Ladakh was Sangri-La. You unfortunately can't go back in time, but still quite secluded

I'd want to go via the roads, highest mountain pass in the world I think up from Daramsala, excuse spelling, I did get there which was great. Loved those Himalayan foothills!

Dharamsala; you are good!

Better via Manali. You cross 4 major passes. Tang Lang La is the highest but that is not the highest motor-able pass.

This one is now the highest

I do love a bit of altitude! Just leave the beer out!
