You will find a stone monument at the top, dedicated to the historic Mohave Trail, which was used by Native American tribes.

If you are headed from or toward the Santa Ana Trail, this is a great spot to check out. The falls usually get a fair amount of water flow and make for a pretty stop.

From here you can hike the Santa Ana trail east towards South Fork. This hike can be done as a loop, a multi-day hike, or a point-to-point with a shuttle ride. The trail has a number of camps along the way and is also a popular mountain biking route. The trail is shady and peaceful. The path east of here is quite flat which makes the trail enjoyable even in the hot summer.
