Best aashram to stay is Parmarth aashram. I don't have idea about budget. But many tour operators are available in haridwar and rishikesh for char dham yatra. You can search for them on google (map)
Yes, though there are many good aashrams in rishikesh, parmarth niketan is a nice option,.
You may catch buses for guptkashi from 5:30 am.
For a 5 day tour from rishikesh-kedarnath-badrinath-rishikesh , you need to keep approx 8500-9000 inr for local transport travel- kedarnath on foot-food-budget stay option
Hello Mr Lalbahadur,
I am also looking for Rishikesh to Guptkashi bus. Are you 100% sure that the bus is at 5;30 am. I called UTC in Rishikesh and they told me that it is 4 am which is too early for me.
