In Sequoia Park, the 16-mile stretch of road from Ash Mountain to Giant Forest contains 130 curves and 12 switchbacks. For this reason, there is a vehicle-length advisory for the twelve steepest miles within that stretch. From Potwisha Campground to the Giant Forest Museum, the advised maximum vehicle length is 22 feet (6.7 m). An alternative is to take Highway 180 from Fresno to Grant Grove and then proceed south on the Generals Highway.
Maximum legal length limits on the Generals Highway are 40 feet (12 m) for single vehicles or 50 feet (15 m) for vehicles plus a towed unit. If you are towing a smaller vehicle, consider camping in the foothills and using the smaller car to explore.
