The town is formed by small villages at an important intersection between China and Vietnam, and the city has a unique multicultural atmosphere.
A free city map can be obtained in the bus station, with basic information and "things to do".
An online version you can get on the website of the Provincial Tourism Department.

The local Provincial Tourist Office (in Oudomxay City, or Muang Xay) has been offering since November 2006 some very nice hiking including nightstays in khamu family houses (not guest houses, as in other more touristy hike places, which makes the experience very special and intimate). Although not as colorful as other ethnic groups of Laos, the khamu people are very nice and happy to have foreigners visiting their villages.
There are three banks and one post office offering change for cash and travellers' cheques, BCEL , about 1 km north of the bus station change travellers for 3% commission (minimum of US$3). It might be worth checking Lao Development Bank (which might offer a better value).
BCEL provides an ATM, accepting international cards (BCEL charges 20,000Kip, be aware of charges of your own bank).
Luxay market is the market building located opposite the Tourism Office. In this market you can find all sorts of products including international ones, mostly from China and Thailand.
