hot springs

I've been thinking about what I want to do for my birthday this year since it is only a month away and I'm pretty sure I want to spend a weekend at a hot springs. I've only been to Chico and I loved it but there are few other hot springs close by that I'm thinking I need to try out...

Since it is only 43 degrees outside today, I have been thinking of all the things that would make me warm and the first things that come to mind are hot shower, hot hubs, saunas and hot springs! Obviously, the first three are nice but hot springs are by far the superior choice...
