4. Hang gliding: Nilachal (Kamakhya) Hill in Guwahati Guwahati and hills around Kaziranga are ideal for hang gliding.

5. Boat racing: Speed fests similar to snake-boat racing in Kerala have traditionally been organized during festivals in Guwahati, Hajo, Suallkuchi and Barpeta.  For kayaking and canoeing enthusiasts, one can head straight to Charanbeel in Morigaon district, barely an hour's drive from Guwahati.  The Assam Boat Racing and Rowing Association, together with the Department of Tourism, also organizes boat racing during the annual spring-time Brahmaputra Beach Festival. 

6. River Rafting: The Brahmaputra and its turbulent tributaries such as Manas and Kopili dare adventurers with their swift current and fiery rapids.  But rafting is most organized at Jia Bhoroli, also a Brahmaputra tributary.

7. Angling: Rivers Jia-Bhoreli (Nameri National Park), Kopili (Central Assam) and Manas (Manas National Park) are the haunts of anglers for fierce game fish, especially golden mahseer.  The most popular annual event is organized by Assam Bhoreli Anglers Association at Nameri in November or December
