Herard Homestead is an 1870s ranch site in Medano Canyon, above the dunes. Only the foundations remain. It's a brief historic stop if you're already taking the Medano Pass Primitive Road; the trip there is the bigger commitment.
The road chart places the foundations at mile 6.2, between the third and fourth Medano Creek crossings. Reset your odometer at the southern entrance, where pavement ends. Beyond the Point of No Return, only high-clearance 4WD with a low-range 4L transfer case is allowed; AWD and 2WD are prohibited. The road usually opens from mid-to-late May into late November when conditions allow, and there's no cell service. Check current road conditions before setting out. The chart identifies the site but doesn't show a separate pullout, and how clearly the foundations can be seen from the road isn't confirmed.
