It is named after two of the largest and most famous Giant Sequoia trees, the General Sherman and General Grant trees. The highway is notoriously steep, narrow, winding, and difficult to drive, especially its southern section from Hospital Rock to Giant Forest within the park. This section also consists of numerous switchbacks, and has a speed limit of 10 MPH. Regulations restrict the length of vehicles—they must not exceed 40 feet (12 m), although vehicles longer than 22 feet (6.7 m) are not recommended to use the road  between Potwisha Campground and Giant Forest Museum.
The highway begins at a southern intersection with SR 198. The road travels northeast along the middle fork of the Kaweah River and enters Sequoia National Park through the Indian Head entrance. Near the Hospital Rock turnout, the road turns north and goes through several turns before straightening out and continuing northeast, passing near the General Sherman Tree. At Lodgepole Bridge, the road turns west before later turning north. Generals Highway leaves Sequoia National Park through the North Entrance, entering Sequoia National Forest. The road continues northwest through Giant Sequoia National Monument before traveling along the northern border of Kings Canyon National Park, briefly entering it before terminating at SR 180.
Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, based on the alignment that existed at the time, and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers an overlap due to a correction or change, and T indicates postmiles classified as temporary (for a full list of prefixes, see the list of postmile definitions). Segments that remain unconstructed or have been relinquished to local control may be omitted. The entire route is in Tulare County.
