Here's the link to the Cook Forest Scenic Trail Ride Campground.

Spent a week there two summers ago.  The campground is nice - clean and neat but nothing fancy. The proprietors are very nice.  You can rent straight covered stalls or keep your horses hi-lined at your campsite.  Some sights have electric and water.  Food packages are available for some weeks during the season.

Trails are a bit rough - or at least they were when we were there.  Several horses lost shoes so bring boots in case of an emergency.  They will get a farrier for you if you need one.

Josh Lyons was there as a clinician and we had a good time with him and his crew.
