Sausalito Path

Highlight (Segment) • Cycleway

The Sausalito Bike Path runs through Mill Valley. It's a paved route with great views of the wetlands on the old Northwest-Pacific rail line, which operated from 1884 until its closure in 1971. The path ends near Mike’s Bikes in Marin City, where riders can continue along the busy Bridgeway into Sausalito or take quieter marina backroads.

Baker-Barry Tunnel

Highlight • Structure

This tunnel is one-way with a stoplight that lets each direction pass through for five minutes. It has a common name referred to by locals as "The Five Minute Tunnel," although officially named name Baker-Barry because it connects two old military bases.

Golden Gate Bridge North-West 🌉 Conzelman Rd bike access

Highlight (Segment) • Bridge

Fort Baker

Highlight • Historical Site

Fort Baker is a historic army post located in the Marin Headlands. The post, built between 1902 and 1910, is one of the park’s best examples of the army’s “Endicott Period” military construction, named after the late 19th century Secretary of War, William C. Endicott. Mostly transferred to civil purposes since 2000 including hotels, the Children's Discovery Museum, etc., the U.S. Coast Guard Station Golden Gate, located at Horseshoe Cove, is responsible for search and rescue missions, homeland security, maritime law enforcement, maritime environmental protection and boating safety. The Travis Air Force Base continues to operate the Sailing Marina Center at the Presidio Yacht Club. nps.gov/goga/learn/historyculture/fort-baker.htm

Sausalito Houseboats

Highlight • Settlement

The Sausalito houseboat community is full of architectural gems and repurposed old working boats, and each is wonderfully unique. Bikes are not allowed on the dock, so you must park your bike to get a closer look; however, remember to be respectful when visiting, as these are residential homes, and you are close to someone's living space.

Bothin Marsh Preserve

Highlight • Natural

This 106-acre preserve incorporates a 2-acre tidal wetland that’s a small reminder of the vast salt marshes that once surrounded San Francisco Bay. A quiet inlet at the north end of Richardson Bay, surrounded by cordgrass and pickleweed, it’s home to several endangered species and many shorebirds and waterfowl rest and feed here. The Sausalito-Mill Valley bike path, and the branch to Tennessee Valley/Mt Tam, are paved through the marsh.

Molino / Edgewood Avenue & Sequoia Valley Road

Highlight (Segment) • Climb

Quieter albeit slightly higher and steeper climb out of Mill Valley to Panoramic Highway instead of climbing on Hwy 1, meandering along lesser traffic neighborhood streets with more shade and awesome bay views.
