Once in Chiang Khan, you can pretty much get around on foot. Most guesthouses are on SriChiangKhan street, which is the main walking street of this charming little town. Walking street is about 20 blocks long, and you will spend most of your time there. There is a 7-11 at a block's distance on the road parallel to walking street. If you plan to go to Kaeng Khut Ku (worth checking out), you can take a tuk-tuk for around 50 baht each way (depending on the number in your party).
