Operating Hours & Seasons

The monument is open 24 hours per day, all year, but some roads and facilities are closed during the winter months.There are no dinosaur fossils visible on the Colorado side of the monument. If you want to see Dinosaur Fossils, you must visit the Utah side of the monument near Jensen, Utah. Because Dinosaur's biggest collection of dinosaur fossils are protected within a secure structure known as the Quarry Exhibit Hall, visits are only allowed during certain hours.

See dates and hours of operation for monument visitor centers below. Transitions from peak to off season hours depend on staffing levels and weather - call with questions.

Peak Season (Summer Hours)

During the busy season, a shuttle bus takes visitors from the visitor center to the Dinosaur Quarry every 15 minutes from 8:00 am to 5:00 pm. The last shuttle for the day leaves from the Quarry Exhibit Hall at 5:30 pm for the return to the visitor center.

Visitors with accessibility needs, or those who are traveling with pets, should inquire at the information desk at the visitor center for directions on how to access the Quarry Exhibit Hall in their personal vehicle.

Off Season (Winter Hours)
September 17, 2018 to late May 2019
Open daily, 9:00 am to 5:00 pm

From September 17 to October 21, 2018 you may drive up to the Quarry Exhibit Hall during open hours on weekdays and take the free shuttle on weekends. The shuttle will also operate from October 18-21. A ranger is stationed in the Quarry Exhibit Hall to answer any questions you might have.

Starting October 22, 2018, due to reduced visitation and staffing in later fall and throughout the winter and early spring, a ranger will lead vehicle caravans at set times throughout the day. Visitors begin at the Quarry Visitor Center and drive their personal vehicle to the Quarry Exhibit Hall, following the ranger. Caravans depart the Quarry Visitor Center at the following times:

  • 9:30 am

  • 10:30 am

  • 11:30 am

  • 1:00 pm

  • 2:00 pm

  • 3:00 pm

  • 4:00 pm (This is the last caravan of the day)

If you arrive after a group has departed, you may have to wait approximately one hour before the next departure. While you wait, there is a twelve minute film, exhibits, and a bookstore in the visitor center to occupy your time. You can also take a scenic drive on the Cub Creek Road. REMEMBER: The last caravan to the quarry is at 4:00 pm.

Each tour of the quarry lasts approximately 45 minutes. Visitors who wish to spend more time in the quarry must exit the Quarry Exhibit Hall until the ranger brings up the next group.

It is best to anticipate the timed caravans if visiting between mid-October and early May. Please call the Quarry Visitor Center on the day of your visit if you wish to confirm the procedure for that day.
