Opening of the road
The road is closed during the winter months due to the heavy snow that falls which makes it either entirely blocked, or unsafe even in those area which are not actually blocked. Generally the opening is considered to be Memorial day and the closing ti be Labor day however these are only a guide. In practice the actual weather conditions each year and observed by park staff to make the decision on when the road should be closed.
To find out the current status of the road opening call 970-627-3471 (open from 8am-4:30pm) to ask whether the road in spring and autumn months are opened.
Although the road is most comfortable during the summer months if you want to really appreciate the snowy alpine atmosphere then visiting in May or just when the road has opened will provide the more impressive scenery.
VISITING OUT OF SEASON
Out of the open season there are still things to see at Trail Ridge Road. The closure of the road actually only occurs around or just past Many Parks Curve so if you can visit that lookout point you’ll have some great views already.
