FATMAP difficulty grade
This route uses a substantial amount of forest service roads to create a lollipop loop ride with the Elkhorn Crest Trail and the Twin Lakes Trail.
To complete the route as mapped here, park in Marble Creek and grind up the forest road to reach the Crest.
Turn right on the Elkhorn Crest, then left to drop down to Twin Lakes.
Once off the singletrack, grind back up to the Crest via a network of USFS roads, and drop back down to Marble Creek.
