The San Juan Skyway climbs from Dolores over Lizard Head Pass

The San Juan Skyway runs through Dolores, Cortez, and Mancos and climbs north over high Lizard Head Pass, a paved but serious mountain drive with real winter weather.

Published June 10, 2026 - Last verified June 11, 2026

The San Juan Skyway is a long loop through southwest Colorado, and Montezuma County sits on it. The byway passes through Cortez, Dolores, and Mancos before heading up into the mountains. From Dolores, the road climbs north along the Dolores River and over Lizard Head Pass, a high crossing above 10,000 feet, on the way toward Rico and Telluride.

The word “byway” can make it sound like an easy cruise. The pavement is good, but this is a real mountain drive. The road gains a lot of elevation, weather changes fast, and Lizard Head Pass can hold snow and ice well outside of winter. Storms can blow up on summer afternoons. Wildlife on the road, slow trucks, and bicyclists are all part of the picture.

Why this matters for a newcomer: the drive north out of Dolores is beautiful, but treat it like a mountain pass, not a quick connector. Carry warm layers, keep your fuel up, and in the cold months be ready for winter driving and possible traction rules.

Check current conditions and any traction or closure notices through CDOT and the COtrip road information before you head over the pass.
