This was a great stop on a trip from Wichita to Topeka. We had planned on spending two hours here but ended up hiking for four. You hike to get to the pasture where the bison graze. It was a breathtaking experience to find the herd. Just make certain to wear appropriate sun protection (as there is no shade) and to bring water. There is also an old school house you can visit. The visitor center has a water fountain with a bottle filler and restrooms. The park rangers were friendly and helpful. They also offer a van tour.
