Crissy Field to Sausalito and Tiburon over the Golden Gate Bridge

From Crissy Field East Beach the ride follows the bay shore west below the Presidio to Fort Point, then climbs to the Golden Gate Bridge and crosses it on the sidewalk, 1.7 miles from end to end. From Vista Point on the far side it drops down Alexander Avenue into Sausalito and along its waterfront, then follows the Mill Valley-Sausalito path past the marshes at the head of Richardson Bay and round to the old railway path into Tiburon.

It is 24.6 km (15.3 miles) one way with 114 m of climbing; allow about 1¾ hours of riding. The grade is Easy. The climbs are short; the steep one is up to the bridge.

This is not traffic-free: about a third is on roads with traffic, down Alexander Avenue, through Sausalito and on Tiburon Boulevard's bike lanes. On the bridge, bikes use the east sidewalk on weekdays until 3.30pm and the west sidewalk later; at weekends, both until 1 November, then the west one only. The limit is 15 mph, and 5 mph round the towers.

Parking at Crissy Field East Beach is free. Golden Gate Ferry boats from Sausalito and Tiburon carry bikes free to the Ferry Building in San Francisco; the fare is $8.50 by Clipper card.
