Many of the roads through Dinosaur National Monument can become impassable due to snow, rain, or runoff. During the winter months, few monument roads are plowed, which can make vehicle use difficult or impossible. Become familiar with forecasted weather conditions before driving on unpaved roads – do not attempt to drive on unpaved roads when rain or other moisture is forecasted.
