When you walk to King's Pinnacle, you can choose to take the more difficult Pinnacle's Trail or to go by way of the Turnback Trail. I'd recommend going up Pinnacle Trail. It's not really too difficult and you can always stop and rest and take things at your own pace. Plus, while Turnback Trail is less steep, there are more loose rocks along the trail then on Pinnacle's steeper trail.
If you head southwest from the visitor's center at Crowder's Mountain State Park, you'll be hiking toward Pinnacle's Peak. In my opinion, this is the most difficult trail in the park and it's not as popular as the Crowder's Trail which takes you to the official Crowder's Mountain overlook. You'll be breathing heavy when you get to the top, so sit awhile and enjoy the view. It's great to watch the raptors in the sky circling the peak and to look out onto a few feet in front of you and realize that you are sitting in the tops of giant trees.
Belmont Abbey College is a great little private college just off the freeway (I-85) between Gastonia and Charlotte (Belmont-Mount Holly exit). It's a pretty campus, which you can tour in a half hour or so if you just want to walk around and shoot a couple photos. This photo is of the abbey, which was named a Minor Basilica by Rome in 1998.
Downtown Belmont is a quaint little town and has some really exquisite mansions just outside the main business district seen in this picture.
