Here’s a picture of a hiking group at the top of Castle Rock, one of the two massive rocks on the Rockbrook Camp property (the other one being Dunn’s Rock). From up there, the view is out across the French Broad River Valley and out to the Blue Ridge Mountains. It’s an amazing spot to see Cedar Rock (another climbing destination) and on a clear enough day, Tennent Mountain (a backpacking spot up near the Shining Rock Wilderness area). Sitting at this spot on Castle Rock your elevation is almost 2,450 feet above sea level. Below you is a 150 foot rock cliff and further below is the main part of camp which has an elevation of 2,250 feet.
You knew hiking the trail from camp to Castle Rock was steep uphill; now you know how much! You’re hiking up about 200 feet in about half a mile.
