Windmill Hill Nature Preserve Trail is a 5 mile loop trail located near DeSoto, TX. The trail is primarily used for mountain biking and is accessible year-round.
It's an adequate beginner's trail. It's not too large, too steep or too hard. Some of the trails like Pecan, get deep into the woods, which are really beautiful. (If you are on the trail during high noon, I highly recommend you take the trails in the woods, as it will keep you a lot cooler.) The Bluebonnet trail is a good starting off point for a trail run, which then leads you into Eagle, which is mildly steep and full of twists and turns. Can't remember which trail, but have seen more than one cotton-tailed rabbit in Windmill, which is always a cute sight. Watch out for the spiders overhead in the trees and be sure to clear your path. It's a great trail to cut your teeth on if you're starting out with trail running, hiking and/or mountain biking.
