So we travelled to munnar 3 months back and it comes out to be one of the awesome trips. The whirlwind hilly root will definitely take your heart out, especially of you are going in govt bus. Hatsoff to the bus driver skills. To roam around the top of munnar we booked a cab and the driver will guide you through all the important places like rose garden, waterfalls, view points, tea, coffee plantation and other attractions on-the-go. Night stay and camp fire is must do at munnar. Enjoy the local cuisine especially bhajji and tea at evening. Plan for 2-3 day trip to escape from the crowd and spent some time with nature.
