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.

This trail leads to Angelus Oaks where you can turn onto the Santa Ana River Trail. Both trails combined will make a fantastic 20-mile loop that is technically challenging and offers wonderful views.

Santa Ana River Trail – aka SART – can be ridden as a loop or as a shuttle ride from South Fork Campground to Angelus Oaks. This trail is really fun and sometimes also very challenging. Watch out for sections with deep sand as they can be surprisingly tricky. Great views over Pinezanita – highly recommended!
