For a top-of-the-world rush, hike the six-mile trail to Harney Peak. It starts near Sylvan Lake Resort and climbs to the historic stone fire tower at 7,242 feet above sea level. It’s the highest point east of the Rockies and the stunning view sweeps across four states. Just hold on to your hat as the wind rushes across the mountain. You also can enjoy a gorgeous (and less strenuous) view from Mount Coolidge, another historic fire tower. It’s off Highway 87 and up a 1.7-mile gravel road suitable for most vehicles. The view from here (6,000 feet in elevation) or the nearby Heddy Draw picnic area stretches east and encompasses the Badlands on a clear day.
