The lower end of the route begins at either end of the Duboce Bikeway in the block of Duboce Avenue just west of Market Street. The elevation is approximately 100 feet (30.5 m) above sea level. It then moves in a zig-zag toward the northwest along Duboce Avenue, Steiner, Waller, Pierce, Haight, Scott, and Fell Streets to the Panhandle Bikeway, 215 feet (65.5 m) above sea level. After climbing 50 more feet, the peak of The Wiggle is reached near Stanyan Street at the peninsular drainage divide, i.e., the dividing point between surface water flowing to the San Francisco Bay

The route

Below are five route-finding techniques for those who follow the Wiggle: Geography, Signage, Map, Directions and a Mnemonic trick.

Geographic route-finding

Without memorizing streets, a simple pattern will produce the route easily. The rider or pedestrian wishing to go on the flattest route makes a turn toward the north or west each time the forward direction presents a hill steeper than the turn.

Thus, starting northbound on Church at Market or westbound on Duboce at Market this pattern will avoid all steep areas and produce a route from Market Street to the bike path in the Panhandle of Golden Gate Park and the main routes through the Park itself. Similar "wiggles" can be found using this method for reading the geography in other hill areas, though this wiggle route is known most widely.

Signage

Follow the Bike Route 30 signs from Duboce Avenue westbound (at Market Street or Church Street). In some places, the signs also say "The Wiggle."

Mnemonic trick

The initial letters in the sequence of roads follows the consonants in SWaP HiS: Steiner, Waller, Pierce, Haight, Scott

OR

you can use:
Da Small White Pigs Had Some Figs: Duboce, Steiner, Waller, Pierce, Haight, Scott, Fell. (West bound)

Fa Sho Hannah Played With Sand Dunes: Fell, Scott, Haight, Pierce, Waller, Steiner, Duboce. (East bound)

The hills adjacent to the route, on the northeast side are made of underlying serpentine rock:

Over thousands of years, the gentle valley bottom was formed through a process of gradual erosion of the soft, crumbly serpentine. This flat creek bed contained, until roads and other construction obliterated them, the intermittent stream of the creek itself and two ponds. as with all such flat valleys, the location of ponds tended to shift, but they were generally located at what is now Divisadero Street near Oak Street and at Market Street from Belcher Street to Reservoir Street—a little known public street which is currently the parking lot entry for the Safeway grocery store at 2020 Market Street. (The back of this store is located at the start of the Wiggle.) The reservoir referenced was the successor to the pond.

Human history

Before Europeans settled in San Francisco, a route approximately following that now known as "The Wiggle" was used as a way to avoid hills while walking. A summer village called Chutchui existed beside the area where The Wiggle meets Market Street. The path went toward what is now the Panhandle and then connected to the winter village area at the northern tip of the San Francisco Peninsula near the current site of Crissy Field

When the San Francisco Presidio and the Mission Dolores were founded in 1776, the trail became a horseback connector eventually called "the Old Spanish Trail." In the 19th century, the trail was the commute route of military personnel who lived in the Mission District and worked at the Presidio. In the 1860s, it finally was widened to become a toll road, passable by carriages, and going by the name "Divisadero" or "Devisadero" Street. In the 1870s, a grid of streets was imposed in its place, one retaining the old road's name, across a newly formed neighborhood with all the sandy hills and steep gullies filled or scraped flat.
