After reading about this area in the latest PATC newsletter, and seeing it was quite close to home, we decided to pay it a visit. Our hike was relatively short, just over three miles - the entirely of the blue trail, with a loop on the red, orange, and yellow trails. We were pleasantly surprised by how nice it was!
Most of the blue trail follows Furnace Branch, and the far end of the trail is a lime kiln. There were several stream crossings along the way; only the first was bridged. I'd like to visit the entirety of the red and yellow trails out to their trailheads next time.
