On one of our trips last summer, we were coming from Monument Valley through Mexican Hat headed to Capitol Reef National Park. The Good Sam trip planner routed us on UT 261 over the Moki Dugway. Here's the rest of the story:
The Mokee (or Moki) Dugway, located on Utah Route 261 just north of Mexican Hat, Utah is a staggering, graded dirt switchback road carved into the face of the cliff edge of Cedar Mesa. It consists of 3 miles of steep, unpaved, but well graded switchbacks (11% grade), which wind 1,200 feet from the valley floor near Valley of the Gods to Cedar Mesa.
The State of Utah recommends that only vehicles less than 28 feet in length and 10,000 pounds in weight attempt to negotiate this steep (10% grade), narrow and winding road. Most vehicles can travel the route safely. Caution is advised for motor homes or vehicles pulling trailers. A parking area near the top provides a stunning view of Valley of the Gods.
We made it to the top without incident (thanks to diesel power and 4wd) and made sure to inform the Good Sam folks about the mis-information as soon as we got home.
We are planning a return trip to spend more time touring and exploring Valley of the Gods but we'll bypass the Moki Dugway
