The hills of Marin Headlands can pose a challenge to some, but to most folk the 500 foot (150m) climb up Hawk Hill is worth the effort.

Enjoy the views of the coastline, the bridge and the rolling hills and you'll be distracted from the climb. And if at any point you decide that this one big hill isn't for you .. simply turn around a... Morend head back to the bridge.

Check out the elevation profile for more details, but remember that the vertical scale is exaggerated and the route doesn't look as bad as it appears.Less

A side trip here would add 0.9 miles to your total journey. There's elevation gain of 174ft (53m) to reach Lombard Street.

One of the most iconic images of San Francisco, Lombard Street is also one of the crookedest streets in the world. The quarter-mile long switchback road was designed this way in order to reduce the hill's natural 27% grade, which was considered too steep for cars and pedestrians alike.

Travel back in time to see how 19th Century sailors fared on the Pacific Ocean at the San Francisco Maritime National Historic Park, which includes tours of historic vessels, a visitor center, a maritime museum, and a library/research facility.

The Panama Pacific Exposition of 1915 was an event dedicated to progress, the celebration of the completion of the Panama Canal and the rebirth of San Francisco following the disastrous 1906 earthquake.

A side trip here would take you to the Presidio area which you may choose to explore in depth. View our Free Ride guide to see more details of routes in the Presidio.

In 1846 the U.S. Army took control of this once windswept dune area from Mexico and transformed it into a large military base called The Presidio. In 1994 the National Park Service took over the area and it became part of the Golden Gate National Recreation Area.

Today, the military buildings still stand, although non-profits, busi... Morenesses and apartments now occupy the refurbished premises. In addition there are over 25 miles of hiking trails, 14 miles of paved roads (perfect for cyclists), a golf course, bowling alley, tennis courts and athletic fields.

Today's Presidio has as much in common with Star Wars as it does wars past. The revitalized former military base is now home to many companies including famed movie special effects artists Industrial Light and Magic and LucasArts. This modest Jedi statue is a welcome nod to the current tenants. Impressive, it is.

Celebrating the life and achievements of the father of Mickey Mouse, the Walt Disney Family Museum is a relatively new addition to San Francisco having opened in 2009. The museum is a great attraction for both children and adults alike, as it presents the story of the man's rise to great things, as told by himself and those who knew him well.

In contrast to its name, Long Avenue is quite short. Dismount and walk if you're feeling uncomfortable.

The World Records that the Golden Gate Bridge held back in 1937 may have now been surpassed, but the jewel in San Francisco's crown remains proud as an icon of engineering and art-deco design and possibly the most recognizable bridge in the world.

Well done on making it to the highest point on this route! Now check your brakes and get a tight grip on your handlebars because it's all downhill from here!

Built in 1855 and relocated in 1877, the Point Bonita Lighthouse was built to guide ships coming entering the San Francisco Bay during the gold rush era. Now operated by the U.S. Coast Guard, the lighthouse is still guiding ships into the Bay.

To visit Point Bonita and the lighthouse you'll have to lock up your bike at the trailhead... More and proceed on foot for half a mile. The trek along the cliffs, over bridges and through a narrow tunnel is a memorable one even before you reach the suspension bridge to the lighthouse.

The trail operates limited hours so be sure to check before setting out.

Popular with surfers and sunbathers alike, this sheltered Marin Headlands beach is a great location to hang out and enjoy the ocean shore.

Keep to the cycle lane on this single-track section of the road and there'll be plenty of space for both you and the cars. Head for the light at the end of the tunnel, and consider the 500ft of hill above you that this short-cut saves you the trouble of scaling!

Bear right at the junction and head up the short hill back to the Golden Gate Bridge. Or, you could cut your return journey short with an alternative 1.7 mile route to Sausalito, where you can catch a return ferry back to SF.

The alternative route takes you to the Sausalito ferry dock in just 1.7 miles, cutting 3.5 miles from your tot... Moreal journey length. The route is mostly downhill with a single short uphill segment.
