The Kayan long neck hill tribe villages are a major tourist / multimillion dollar attraction in North Thailand with villages all over the place in different areas of the North, plus elsewhere around the country. For some it’s all a bit odd & there is a wealth of misleading info & stories circulating about them. I was first out with the long necks in MHS in the late 80s. Nai Soi was the refugee camp where they were. more to come....of course.
