The last weekend in September we drove up to Crystal Hot Springs which is just north of Brigham City. They mix water from a Hot Spring and a Cold Spring which makes the temperature about 100 degrees. IT felt like swimming in a big bathtub and the kids loved it.
By far the kids favorite part was playing in the waterfalls.
My sister Nona drove down from Logan and spent the afternoon with us.
