I remember Mirror Lake... nice little spot to be at. I always liked the hot springs, the caves are neat - a little toasty, but you get used to the temperature and it really relaxes you afterwards. The 5 degree cold pool outside is a real shock after that! It's much more refined and polished than it was in the late 70's when I lived there (there never used to be lights in the caves, so it was rather dark).
If you're heading to Kaslo, check out the SS Moyie sternwheeler museum for an interesting look back in history (if you haven't already, that is!).
