Walking is the only option in the old town, while taxis are often the easiest way around the rest of town for ¥7 June 2008. Make sure you have the exact location info or address for the cab driver. Some of them do not know a whole lot more than you do.
Fracture alert: watch where you are walking. It is easy to trip on the cobblestones or fall into the canals from the walkways or bridges, many of which do not have handrails. The cobblestones can be very slippery when wet.
To see the sights outside the old town, the options are walking, biking, public bus, private mini-bus, or taxi. The public bus mainly stays within the city and stops 8PM-PM. The mini-buses are the same price as the public bus within the city. They will have the number of the bus on the front windshield. The price of a mini-bus to a nearby village is ¥2-5, but the starting location within the city is different for most villages. If you do not know where you want to go and are limited on time, the best option is to rent a taxi or mini-bus for the day, but the price can vary wildly from about ¥100 all the way up to ¥300. The price mainly depends on whether you can speak Chinese or not, and how comfortable you look when you try to bargain the deal.
