Ebbets Pass (Route 4) also begins at the junction of Route 4 and 89. Continue on Route 4, paralleling a bubbling mountain stream, through a long, pine-shaded, 12-mile zigzagging eastern approach to the one-lane summit, capping out at 8,730 feet. Watch for mesmerizing views of distant mountain peaks with paramount canyons plummeting thousands of feet below the highway. This front side of Ebbets pass proves to be the most technical descent on the list, so lay heavy on the brakes around the dozen or so blind hairpin turns. Ebbets pass is one of the least trafficked passes in the Sierra Nevada, rendering an ideal situation for cyclists who particularly despise sharing the road with automobiles. Source:
