Meadow Hot Springs in Central Utah is a great family-friendly spot to hang out and soak in warm water. It's conveniently located right of I-15 and there's no hiking involved, so it makes for a great, quick soak when you are on a road trip. Meadow Hot Springs is located on private property in the middle of a cow pasture, but they do allow public access. There are a total of three pools to soak in, all around 100F degrees. The most popular pool is one of the smallest and closest to the parking area, and it is also the warmest. Each of the pools have algae in them, so it is wise to wear water shoes to keep from slipping on the rocks under water.
