This is my local go-to hike, and I try to do it once a week. The first climb up to Windy Hill is strenuous but can be done in 45 - 60 minutes depending on your pace. There is a picnic area with lunch tables and a bathroom about 10 minutes past the Windy Hill summit. After that the Lost trail is a nice and relaxing walk through the woods, and the Razorback Ridge trail is the best way to get downhill without destroying your knees. Total hike time for me (with a short lunch break) is about 3.5 hours.
