Hi Rishabh! This is the best month if you are planning to visit the high altitude places in Kerala, like Wayanad, Munnar, Wagamon, etc. The landscapes will be lush green and weather will be completely chill and foggy. Also, you would be able to witness the amazing decorations and activities during Christmas/New Year's Eve if you plan to travel around that time. Some of the best spots for that are, Fort Kochi Area in Kochi and Varkala in Trivandrum! But, be sure to book in advance as there are chances of huge influx of tourists during this month. Hope you have a great trip!
