anyone know any traditional ones?
In Karnataka newly married couples go to Talakaveri, which is origin of Kaveri. It is known.
You mean Haridwar, Rishikesh, Gangotri, Kedarnath, Badrinath and Yamunotri?
I've been there. Until and unless the couple is extremely religious, won't recommend it for a honeymoon trip. If hill stations are required, go to Ooty and Manali.
Our blankets were soaked in dew drops during summer afternoons in Yamunotri. That's how it is there.Yeah I have been there too. But except religious angle, I'd say those places are great considering nature and environment too.

Gangotri has more comfortable and pleasant atmosphere.
Kedarnath is harsh. Plus the 14-15 km hike to the temple is really tiring.
Badrinath gets pleasant again.
Haridwar and rishikesh can be visited literally any time of the year.
Darjeeling...
Train ride from Siliguri to Darjeeling for new couples as well for married ones is always great...
It's no longer there.
What is no longer there? The Train?
Yes. The toy train has been shut down.
It now runs from Darjeeling to Ghum - Joy Ride.
The bus train ride is horrible rather taking a private vehicle will be a memorable experience...krishnandu.sarkar
