Special Considerations
- The mountain passes at Reservation Ridge on US 191 in Utah and Douglas Pass on CO 139 in Colorado can be treacherous during winter storms. These roads are rarely, if ever, officially closed but sometimes a few hours delay would be prudent.
- All points along the Diamond are subject to snowfall with snow cover lasting longer in the northern and higher elevation areas than in the lower elevation and southern portions.
- Dinosaur trackways are difficult if not impossible to see under snow cover.
Restrictions
- The Cleveland-Lloyd Dinosaur Quarry is closed during the winter months.
- Cleveland-Lloyd Dinosaur Quarry is at the end of 13 miles of gravel road that is accessible to family sedans in all weather except deep snow.
- The Mill Canyon Dinosaur Trail and Copper Ridge Dinosaur Trackway can be reached by a couple miles of dirt road, accessible to 2-wheel drive vehicles in good weather but not advisable for the same vehicles in wet weather.
- Tour buses are not able to reach Mill Canyon Dinosaur Trail and the Copper Ridge Dinosaur Tracksite.
Seasons

The byway can be driven year round.
- Fall
Many seasoned travelers prefer autumn months to travel this byway, due to moderate temperatures and a relative lack of crowds.

Summer is the busiest time to drive the byway.
- Shoulder Season
April, May, September, and October are especially nice times to drive and explore the many features of the byway.
- Spring
The byway is quite pleasant during spring, especially in the warmer southern sections of Utah. Moab is a popular Spring Break destination, however. Travelers should be especially prepared for sudden changes in the weather in spring.

It can be very hot during the midsummer months along the byway.
- Winter
During the winter months, the southern section of the byway near Moab is still enjoyable for activities such as hiking.
