This trail is a fairly strenuous 3.3 miles (one way) trail. Before starting, you should register at the Nature Center, and remember to take along plenty of water for the hike. The Pinnacle Mountain Trail begins at the Nature Center. You will take the Carrick Creek Trail to the left when you get to the sign for Carrick Creek and Table Rock trails. You will follow this trail along Carrick Creek. When you see the sign for Pinnacle Mountain, go to the left. From this point you will follow the yellow marks. You will find this to be an adventurous trail with downed trees and rocky passes that you will have to climb. Along this trail you will be able to see Mills Creek Falls and Mills Creek Pass Trail (look for signs) on your right. If you continue uphill, you encounter Bald Rock. From this point you will be able to look out over the mountains to see Greenville in the distance on a clear day. The Pinnacle Trail continues uphill toward the left on a less trodden trail. The Foothills Trail will branch off to the left just before you reach the orange blazed stack of rocks. You can return the same way you came or take the less strenuous Ridge Trail to the Table Rock Trail. This will lead you back to the Nature Center.
