@ Anup sir-Dhiraj is correct. It is 400-425 KMS from Delhi. Doable without a night halt
there is an alternate route which is good in terms of roads but with sharp turns. It is via Tehri Dam. We were told to be cautious of black ice on this route but we did not encounter any
If one does not has the vomiting sensation while in hills, this route is better-but it is 50 KM longer. very scenic.
@ citylife--Thats correct, the rooms have fans and I am sure the temprature during May June will be much higher. should be 10-15 celcius.
but if you are planning to cover the below places as mentioned initialy, you should not worry about the weather as higher places will still be pleasant all time of the year.
Ukimath, Chopta, Kedarnath, Guptkashi, Deoria Tal
