Monument Peak is accessible via Bailey Canyon Road. Hikers will encounter rocky paths, creek crossings, and switchbacks that lead to a ridgeline. From the top, the views are worth he climb. You will find a stone monument at the top, dedicated to the historic Mohave Trail, which was used by Native American tribes.

From here you can take Clark's Grade down the mountain toward Clark's Ranch Yellow Post Site or head over to Bellyache Springs. The views are great from the summit and from the road, which is popular for mountain biking, hiking, and off-roading.

The viewpoint from this part of the trail is fantastic, and the trees are perfect for setting up a hammock. The trail north of here is nice, scenic singletrack.

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.

The picnic area is a popular trailhead for hiking up to Skyline Ridge and Grand View Point. You can get to the Cabin 89 Trail and Pine Knot Trails from here. There are bathrooms and picnic tables at the parking lot. You may need to pick up a $5 pass to park in the national forest.
