Planning the drive
Hecker Pass crosses Mount Madonna at a modest 1,339 ft, and it shows in the numbers: 18 bends over 7.9 miles is a much lower density than the Santa Cruz Mountains' tighter roads, and the grade never exceeds 6.2%, the gentlest climb in this catalog's Peninsula/Santa Cruz cluster. The character is continuous, banked curves rather than switchbacks — a sustained rhythm road through redwoods and farmland on the Watsonville side, not a technical climb. Wikipedia: Hecker Pass
