This is inside a Kansas State Park, so you need a permit for use.
This trail was designed for hiking but is open to biking too. If you take a right at the trail split, it's a decent ride for the first third of the trail. Then it has several areas with so many large rocks that you have to dismount and walk. There are two large ravines that the trail crosses and instead of building switchbacks, these trails dive right down the side of the hill to the bottom. Kansas Singletrack Society is currently discussing possible improvements over the next several years that will make this a great ride, but for the time being, it may be best to leave this one for hikers.
