There are loops at the top to make your ride longer if you have a cross-country bike (Pauley Creek, Big Boulder and Lavazzola). The downhill is over 14 miles long and offers a two alternate routes in the middle... Third Divide, smooth singletrack strictly downhill or Second Divide, cross-country singletrack. The Downieville Downhill requires strong Intermediate skills to ride it. The Cross-Country alternate routes are also strong Intermediate. The trails are well defined and lush.
