Fossil Springs outputs 72-degree spring waters 24/7. To us it's the most beautiful spot in the State. As you hike you'll think that nothing special lies down in the canyon. In the canyon you'll see some cool rock formations though mostly just a dry or near-dry creek. Then...you keep walking...and all of a sudden things change and rapidly. Then it starts...amazing beauty, springs popping out of nowhere the size of manholes, and eventually a raging creek with swimming holes. A must-do hike in Arizona!
