As Early As May 7th, as Late as June 26th–Trail Ridge Road Opening in the Past.

in Local News

Recent snows keep creating huge drifts up on Trail Ridge road in Rocky Mountain National Park.  Snow plows have to re-plow many areas as they head from each direction and usually meet somewhere near the Alpine Visitors Center to get it fully open.

What's your guess on when it will open this year?
