Old Fall River Road is the original road that took you over the Continental Divide before Trail Ridge was built. It’s a one lane dirt road that climbs 5,000 ft up the side of a mountain. As cyclists we can ride this road anytime that cars are allowed, but with the condition that the road is a one way when cars are allowed. This simply means that for a majority of the year you can ride up Old Fall River and then come back to civilization on Trail Ridge.
