Lower Ruby Jewel Access provides vehicle access to State Forest State Park's Ruby Jewel Route, a 4-mile multi-use trail near the South Fork Canadian River suitable for hiking, horseback riding, biking, ATVs, and Jeeps.

The route is seasonally accessible and offers a gateway to backcountry hiking opportunities within the park; a daily permit is required unless you have the Keep Colorado Wild Pass.

The first mile to the parking area is passable for most vehicles, though 4x4s can continue an additional two miles to the trailhead.
