GRAND COUNTY, LARIMER COUNTY, Colo. (KDVR) — Trail Ridge Road in Rocky Mountain National Park is now open to hikers, bikers and motorists for the season.

There are a few new rules for Trail Ridge Road visitors this year. A timed entry permit is required to travel on the road from 9 a.m. to 3 p.m. Outside of this time frame, a reservation is not necessary.

Those wanting to walk and cycle the west side may only go as far as Milner Pass and the Continental Divide.

On the east side, vehicles may go as far as Rainbow Curve. Walkers and cyclists must stop at Rock Cut.

Park crews are dealing with large rock fall, and ask Trail Ridge Road visitors to be wary, and follow safety precautions.
