Picture this: you're driving along a paved, two-lane, low-incline road that doesn't have any guard rails that block you from the steep edge of a drop-off. But this does not prevent users from taking a Rocky Mountain National Park Tour.
Rocky Mountain National Park is open 24/7 all year long! This park is home to extreme weather, and the winters here can be fierce in the higher elevations. There is no way to predict road closures, but typically, the road is fully open around Memorial Day and closes around mid-October.
