Leukerbad is definitely a small gem if you want something for the whole family to enjoy. Even those that don't do any skiing or snowboarding.
There is a lot to do in town and everything is in walking distance. A lot of nice shops, rodeling and of course the thermal baths.
Can recommend. Check out my video for a impression: youtu.be/4U4N2bkexLQ?si=EeHhxBzNxSrCwtf9
