Along with motel-type accommodations, the park's main attraction is a large (77,053 sq. ft.) artesian spring pool that is open daily and fed by San Solomon Springs. The springs also fill a 'cienega' (desert wetland) and the canals of a refugium, home to endangered species of fish, assorted invertebrates, and turtles. The pool differs from most public pools in several respects: the 1 3/4-acre size, the 25-foot depth and the 72 to 76 degree constant temperature. It also has a variety of aquatic life in its clear waters. With a capacity of more than 3 1/2 million gallons, the pool has plenty of room for swimmers, while offering a unique setting for scuba and skin diving.

not a trail to be had here it's all walking on the roads that campers drive to their spots

The spring feed pool worlds largest is the jewel of this park. One wetland restoration hike about a mile. Nice camping with great shelters!

Wonderful swimming hole on a warm day. Water is crystal clear and refreshing. We even saw the pup fish that is found nowhere else in the world. I'm a fan of good swimming holes and this one ranks at the top of my list.... For activity in describing this place there was not a swimming choice, so scenic drive was as close to anything I could come up with.
