This is a pretty cool loop, starting near the Hanging Rock lake and heading up to Moore's Knob, then going down and heading back up to the parallel ridge and finally capping it off with a jaunt to Hanging Rock and returning where I started from. (Funny how loops work that way).Trip writeup at Two-Heel Drive.
The rhododendrons were blooming only over 2,000 feet -- all the plants at the parking lot level were bloomless. However, the mountain laurel are out in force. Word to the wise: get to lower ground if bad weather comes in; you don't want want to get stuck up there in a lightning storm.
