Nature Conservancy
The Nature Conservancy’s Smoky Valley Ranch is 16,800 acres of predominately short grass prairie.  Much of the land is leased to local ranchers, but 3,000 acres are committed to a buffalo herd.  At the north end is a hiking trail with one or five mile loops that is open to the public.
From Oakley, take US-40 west to the western edge of Monument, Kansas.  Go south on 350th Road for approximately 15 miles to reach the hiking trail.  There is parking and a kiosk on the east side of the road.  The ranch continues for a few miles and has spectacular scenery.  Just a couple of miles past the river you may catch a glimpse of the buffalo herd, and deer or antelope are usually seen in the area.
