Cyclerickshaws are the most convenient means of transportation as hired cars and taxis are not always readily available. If you are a tourist, don't get on the cycle rickshaws in front of the museum that are manned by the persistent teenagers as they will take you on a farcical circuitory route to make you spend more. Use the older guys. Or just walk round the town. Although there are a few to be found, auto-rickshaws are not yet common in this area.

If you are planning an extended stay, it may be worth your while to purchase a bike from one of the many local cycle shops. A brand new bicycle will run you between Rs 2,200-2,600, about US$45-55.
