This trail is a steep, dusty old jeep road trail down past an old gravel pit. There is a lot of loose rock on this part of the trail making it easier to go down than the return climb out. The trail then turns south and goes a half a mile to the springs. From here you can discover the little Shangri La where you can swim, picnic, study fossils, or explore the waters of travertine pools along the creek.
The millions gallons of 72F water that gush from the springs every hour have created a lush environment which supports over 30 types of trees and bushes and over 100 species of birds. The canyon walls near the springs contain small fossils from an ancient sea that washed over the area 350 million years ago.
