The 18-mile Wildlife Loop Road lets one get up close (but not too close) and personal with the park’s amazing wildlife, namely, the Buffalo. I love the Buffalo and at Custer State Park you get the opportunity to see the 1,300 strong herd for yourself on the hills and in the forests. The road is leisurely and on gravel with no 4WD required. Just make sure you bring your binoculars and camera!
