Himachal road transport has annoucned re-introduction of a direct bus service between Delhi and Leh via Manali wef 6th June, 2016. This 33 hours, almost 3 days journey of almost 1050 is sure to make many heads spin. One way fare is Rs.1365/-. When I saw this Delhi-Leh bus at the Leh bus stand during my visit in 2011, I could not digest as to how one can travel non-stop in such an ordinary bus from Delhi. Or how can one drive a bus like a truck driver do. We were told it is one service, but two buses. Now it is confirmed that there is a change of bus, and hence crew at Keylong. However this is an ordinary bus service without any inclusion. There also is a Non-AC delux bus service between Manali and Leh that costs Rs.2700/- one way that includes one night stay, dinner and breakfast en-route. This service will start from July 1.
