Within town, for the most part, walking is quite easy. The tourist information office also has a few bicycles for rent if you'd like to go a bit further. If you need to get to some of the regional monasteries, your best bet is negotiating a package deal with the taxis. You can have the tourist information office help you translate and negotiate, as most of the drivers will not speak English. If a driver tries to change the price on you, absolutely refuse, and take the matter to the police if necessary.
