Peak Season
May 17, 2015 to September 7, 2015

During the busy season, a shuttle bus takes visitors from the visitor center to the Dinosaur Quarry every 15 minutes from 9:30 am to 5:00 pm. The last shuttle for the day leaves from the Quarry Exhibit Hall at 5:30 p.m. for the return to the visitor center.If you arrive between 8:00 and 9:15 a.m., you may drive your personal vehicle to the quarry. The access road closes to uphill traffic at 9:15 a.m.

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.

Late Fall to Early Spring
Through May 16, 2015, and after September 8, 2015

Due to lower visitation and reduced staffing in the Fall, Winter and Spring, access to the Quarry Exhibit Hall is by vehicle caravans at set times during 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 Vistor Center at the following times:

9:30 a.m. 1:00 p.m.
10:30 a.m. 2:00 p.m.
11:30 a.m. 3:00 p.m.
4:00 p.m. (last trip for the day)

If you arrive after a group has departed, you may have to wait approximately 1 hour before the next departure. There is a twelve minute film, exhibits, and a bookstore in the visitor center to occupy your time while you wait. You can also take a scenic drive on the Cub Creek Road. Last caravan to the quarry is at 4:00 p.m.

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.

Occasionally, when visitation, and staffing allow, a ranger is stationed in the Quarry Exhibit Hall so that visitors may drive up anytime during open hours instead of following the timed caravan schedule. This is usually weekends only and is often determined on a daily basis, so it is best to anticipate the timed caravans if visiting between late September and mid May.
