My sister and I stayed here for a little getaway. I have been to many hot springs in Idaho, and this was the nicest I've seen. The buildings and pools are all very clean. I know many people are concerned about the sulfur smell of many natural hot springs, but you really had to sniff to notice any. The outdoor pools range nicely in both temperature and depth, allowing for swimming or just soaking. We were very comfortable on a February day. The poolside changing rooms and lockers (which don't actually lock) are also clean and convenient. There are private pools for rent, but we did not use them. They also have massages available.
There are four domes available if you spend the night. The furnished ones looked very nice, but being avid tent campers, we opted for the 'camping dome.' It is very basic, which we expected. It has a carpeted floor (And yes, it's heated!!) two clip-on lights (one was burnt out) a space heater, a fan, and six camping pads. This was all exactly as advertised. The problem was that the zipper which closes the door flap was completely broken. We were given a single clamp (like a big clothespin) to keep the flap from blowing open. Several of the window/skylights had also lost their seals. Needless to say, since we had food in the dome, we were very concerned that we would be visited by creatures in the night.
Without that concern, we would have had a great night. The camping pads were comfortable, and between the space heater and the heated floor, we were very cozy even though it snowed.
We also drove through the campground the next day and it looked very nice, except being next to the highway.
If you come for the day, you will not be disappointed. If you spend the night - splurge and get a furnished dome.
They also have an alligator.
