Monitor Pass (Route 89) commences at the junction of Route 4 and 89 about five miles outside Markleeville, CA, home to the notorious
Death Ride. Turn onto Route 89 and begin your 9-mile climb to an elevation of 8,214 feet. The ever-changing scenery of Monitor captivates cyclists as they make gentle twists and turns underneath rocky crags, through alpine meadows, tree-covered mountainsides, and rolling hillsides of high-desert brush. Death Riders who ascend this pass at dawn can attest to its healing beauty and Zen-like energy, awarding Monitor the number one vote for most scenic pass on this list. Source:
