Northeast by bike
This great eastern frontier offers some great on-road experiences for the intrepid biker, especially along the long Highway 52. The floodplains of the Brahmaputra, the Mishimi hills and the Lohit and Dibang river valleys all offer a variety of thrills: from biking through the rolling tea gardens of Assam, over dry riverbeds, and on swaying suspension bridges in Arunachal. Head to Parashuram Kund on the Lohit or go all the way to the oilfields of Digboi and Namdapha National Park. Stay in camps, and chart your route as your fancy—and the uncertainties of the road—dictates.
How to do it: Many outfitters can help you with biking trips here, from expensive ones like Ride of My Life (rideofmylife.in) to more affordable ones like Life Away from Life (lifeawayfromlife.com). If you plan ahead, you could easily do it on your own.
