Manali is located in Himachal Pradesh and is one of the most beautiful places in India. I visited Manali last month and it is indeed a veey beautiful place. Ghe scenarios is outstanding and the place is fabulous. Behaviors of people there is also good.
According to be it is a best place for couples and for bachelors too. For couple it is a best place because of the scenario and places you can visit from there. Its a romantic place where couples can spend their honeymoon too. And for bachelors it is the best place beacause it is also a adventure seeking place. You can do manay adventure sports there like paragloding, river rafting, cycling, biking, etc. Overall it is a very nice place to visit.
