I would suggest you to take roadways. It will let you enjoy the beauty of the valleys and mountains; the very essence of the popular hillstation, MANALI.
I would say taking a Volvo bus to Manali from Delhi is the best option. Many buses ply from different parts of Delhi including ISBT Kashmere gate, Majnu Ka Tilla, Himachal Bhawan, etc.
Hi Aman, it usually depends how do you want to travel. Let suppose you want privacy and you dnt have any problem with funds, you will prefer cab or your own car. but you in other case you can prefer Volvo bus, which is best mode of transport to Manali from Delhi. 1. you will not get tired
2. you have enough time to talk, watch movie, listen songs and sleep too
3. you can enjoy more time in talking in place of putting your time toward driving which require concentration
4. you can take cab, but that would be lil costly if you have budget constraint.
If you are on a tight budget I would recommend you to travel by HRTC buses. Else you can hire a personal cab from delhi. The main benefit of personal cab is you can stop wherever you want for a break to get fresh or just take pictures.
An overnight bus journey from ISBT, Kashmiri Gate, New Delhi to Manali is the best way unless you like to drive. in that case one can always hire a zoom car.
I am from chd and visit frequently to delhi qnd manali too..
i will suggest get a volvo to chd.,.,
stay here for a day.,.enjoy the town's beauty'iieess.
to manali the volvo leaves at night so it will be a good option to teavel by night,. . .and stay directly in old manali.
