Hi Sandeep, the best destination would be
Hill view park, Gavi, Idukki arch dam, Painavu, Kulamavu dam, Thommankuthu Falls & a small hill station known as Anakarra. The best time to visit Idukki is in Mansoon session.
Munnar and Vattavada will be the best options for now, because Neelakurinji started blooming here. there are also other places like Marayoor
Meesapulimala
Kalvari Mount
Ramakkal Medu Happy Travel!
