It is open to vehicle traffic roughly from Memorial Day weekend in May through Columbus Day in October. Temporary closings may occur in early June or late fall because of snow. Occasionally it opens earlier in May. Average close date is October 23 (latest close date Dec. 2, 1933) when the Park Service gives up fighting the snow and turns the road back to Mother Nature for the winter. During winter  it is closed between Many Parks Curve and the Colorado River Trailhead.

The many turnouts along the way provide scenic overlooks and tremendous photographic opportunities, day or night. The night time view from Rainbow Curve is spectacular. City lights from Fort Collins to Denver are visible.
Trail Ridge Road travels through forests, above tree line, over the alpine tundra, reaches the high point, and crosses the Continental Divide before winding its way down to the town of Grand Lake. There are numerous trails, short hikes and scenic pull-off spots. The entire trip crosses about 50 miles of spectacular Rocky Mountain scenery and can take anywhere from 2 hours of non-stop driving to an all day trip with scenic and meal stops.
Just west of the high point is Fall River Pass, elevation 11,796 feet, and the Alpine Visitor Center. Many elk, deer and bighorn sheep move to the high country in the summer and can sometimes be seen from the deck of the Visitor Center. Rest rooms, a restaurant and a gift shop are also located in this area.

A note concerning the alpine tundra - This is an extremely fragile ecosystem. Please stay on the marked trails. Crushed growth takes many decades to heal.
