Hi, in my opinion both places are spectacular by its on style . Munnar is famous for its tea plantations and landscape. Ooty is also famous for its blue mountains and nearby wildlife. So choose one which suits you more.
I would definitely suggest Munnar over Ooty due to the beautiful sightseeing spots in Munnar. If you are just looking for temperature Ooty would be a better choice.
Hi Siddhant Go for Ooty because there are more places to explore near Ooty. There is a place few kms from Ooty called Toda Tribe. You should definitely go to that place.
