This is a really fun place to take the kids in the summer. It is basically just like a swimming pool only it is a natural hot spring. The water is comfortably warm and not too hot. They have toys and such for the kids to play with. They even offer swimming lessons. One really cool thing is that they have an RV campground right next door, so you can even just make a weekend of it by camping in your RV and going swimming at the hot springs. It's close enough to San Luis Obispo that you can run into town and get a bite to eat or get groceries if you aren't really into "roughing it".
