It took us about 35-40 minutes to make it to the top. We found it to be just the right amount of difficulty and length for us not to be completely exhausted by the end. I actually wish I lived closer to it so I could go more often. I'd have to say though, if you're going on a weekend, make sure you get there early! It get's pretty busy and parking is limited.
We then headed a bit further up the mountain to Sassafras for breakfast. We stopped in at a cafe called Ripe for some bacon and eggs and a big ol' serving of coffee!
