Written Directions
At the northern base of McClure Pass on CO 133 a small sign indicating "Marble" points you to the east on a well-maintained road (Route 3). Take Route 3 east to the town of Marble, CO.
Scenery
The ride is along a valley with Crystal River running adjacent to the roadway, with Island Lake alongside the road at about 1/2 way to Marble and Beaver Lake at the end of the end (just east of town). Forest and low density population make this a nice enjoyable trip. At the other side of Marble is the roadway (4x4 and trail bikes only) that leads to the ghost town of Crystal. Well worth the 5 mile trek if properly equipped.
The beginning of the route offer a nice ride through some good twists, turns, and great scenery, ending up in Marble -- a small, sleepy mining town. Through town is the terminus of your ride, the Marble yard and mine. Take some time to walk around and enjoy the area and history. It is a nice "add-on" ride if doing the trip between Carbondale and Paonia.
Drive Enjoyment
While not high speed limits, it is a comfortable valley road that has ample sweeping turns and great scenery.
Tourism Opportunities
Marble is a low density population town with virtually no amenities. Make sure you fuel up (gas and food) at Paonia or Carbondale, depending on genesis of ride, or at least stop by Redstone for services. Redstone is just north of Marble.
