While being an old piligrimage city it is congested with trafiic and tourists in main haridwar, but other places far away from Har Ki Pauri is a recommended to stay.
There are nearby temples to visit which are always attactive to travel on ropeways. Hrishikesh being close by is an alternate location to stay where in Kuouman State Govt. Shops are good to shop for.
A Historical place, pilgrimage station famous for the Ganga Aarti, I have attended the aarti for 3 days and it's so peaceful.
I would recommend visiting this place with family for 3~5 days.
Haridwar has a garden with flowing meaning of the gods. So can a lot of Hindu worship are being made daily.
