Kaziranga NP is a must-visit when you are in Assam. I would recommend 3-4 safaris to optimally experience the Kaziranga NP. There multiple zones and every zone is different and beautiful. Each zone has a different landscape, flora, and fauna. Morning safaris are on elephants and afternoon safaris are in a jeep. I personally liked morning elephant safaris more as the animals were alert and refreshed in the morning. Also, it is very memorable to witness sunrise and fog getting lifted off the jungles. We went on 5 safaris in different zones, 3 morning safaris and 2 afternoon safaris. This turned out to be a very memorable trip!
