Begin your day with an early morning safari at Kaziranga National Park, home to the one-horned Indian rhinoceros. After the safari, visit the Karbi Ethnic Village to learn about the local Karbi tribe's culture and traditions. In the afternoon, visit the tea gardens for a glimpse into Assam's tea production. End the day with a sunset river cruise on the Brahmaputra River.
Explore Majuli, the world's largest river island, on a bicycle tour. Visit the various satras or monasteries to witness the unique Assamese form of dance and drama. In the evening, enjoy a traditional Assamese dinner and stay overnight in a bamboo cottage overlooking the Brahmaputra River.
Visit the ancient city of Sivasagar, home to many historical monuments. Start with a visit to the Rang Ghar, an amphitheater that was once used for cultural events. Then, visit the Talatal Ghar, an ancient palace that was also used as a military base. In the evening, visit the Joysagar Tank, a large man-made tank that was built in the 17th century.
If you have extra time, consider visiting the Kamakhya Temple in Guwahati or the Manas National Park. For a side trip, head to Shillong, the capital of Meghalaya, known as the "Scotland of the East." To maximize your fun, try out the local cuisine, such as the bamboo shoot pickle or the fish tenga curry. Don't forget to take a souvenir back home, such as a mekhela chador or a gamosa, both traditional Assamese garments. Lastly, be prepared for the monsoon season in September, so bring appropriate clothing and gear.
