Forest Road 250 is a graded dirt road that follows the Conejos River from Highway 17 to Platoro, crosses Stunner Pass, and then descends to the San Luis Valley along the Alamosa River.
Traveling west on Highway 17 from Antonito, one follows the Conejos River through its broad, alluvial valley. Stream erosion has cut through thick layers of volcanic rock, leaving the flat topped mesas visible along Highway 17.
