There are road trips, and then there are road trips that rearrange something inside you. The drive up Medicine Wheel Passage Scenic Byway — a 27-mile ribbon of pavement and gravel that climbs into the Bighorn Mountains just west of Sheridan — falls firmly into the second category. I’ve taken this route more times than I can count, and it never once feels ordinary.
The byway begins near Dayton, Wyoming, roughly 35 miles from downtown Sheridan on US-14A, and it winds upward through lodgepole pine forests, open meadows streaked with wildflowers in summer, and past sweeping views that seem almost theatrical in their scale. The Bighorns rise dramatically from the high plains, and as you gain elevation, the world below — ranches, rivers, the soft geometry of Sheridan’s streets — shrinks into something peaceful and far away.
The crown jewel of the journey is the Medicine Wheel itself. Perched at roughly 9,642 feet on a flat limestone ridge in the Bighorn National Forest, this ancient stone structure is one of the most significant and mysterious archaeological sites in North America. The wheel stretches nearly 80 feet in diameter, constructed from limestone slabs arranged in a spoke pattern radiating from a central cairn. Researchers believe it was built by Indigenous peoples somewhere between 300 and 800 years ago — possibly much earlier — and it continues to hold deep spiritual importance for many Native American tribes today. The Forest Service manages the site with appropriate reverence: access is on foot via a 1.5-mile round-trip trail from the parking area, and a medicine bundle fence surrounds the wheel where visitors are asked to walk quietly and respectfully.
What strikes most visitors immediately is the silence. Up here, above the tree line, the wind moves through the grass and the sky feels enormous. On a clear day you can see the Pryor Mountains to the north and the absurdly beautiful expanse of the Bighorn Basin stretching to the west. Interpretive panels along the trail offer historical and cultural context, making the walk genuinely educational without feeling like a lecture.
The byway is typically accessible from late May through October, depending on snowpack — call the Bighorn National Forest Paintrock Ranger District ahead of your trip to confirm road conditions. Bring layers regardless of the season; the temperature at the summit can be 20 degrees cooler than Sheridan, and afternoon thunderstorms are common in summer. Pack water, wear sturdy shoes, and give yourself at least half a day to take it slowly.
Whether you are a history enthusiast, a hiker looking for a meaningful destination, or simply someone who wants a drive that earns a long exhale at the end, Medicine Wheel Passage delivers. It’s the kind of place that makes you grateful Wyoming exists — and grateful that Sheridan sits right at its doorstep.
