WW II US 5-inch Gun Turret of SF Winery

If you're looking for best road cycling routes in the Bay Area with unparalleled views, the San Francisco Bay Trail to Treasure Island delivers. This 22.7-mile (36.6 km) route, rated easy overall, offers a unique journey across the Bay Bridge East Span path, providing intimate views of the water and the San Francisco skyline. While much of the ride is a gentle incline, be prepared for the notoriously steep Macalla Road climb on Yerba Buena Island, a segment with grades up to 24% that will challenge even the strongest cyclists before you reach the panoramic vistas of Treasure Island.

Accessing this route from the East Bay via the Bay Bridge East Span path is straightforward and open daily. However, if you're starting from San Francisco, you'll need to plan for public transport; the Muni 25 bus and the Treasure Island Ferry both accommodate bikes, offering a convenient way to reach Yerba Buena Island. Consider starting early to make the most of the views and to tackle the challenging ascent before it gets too busy.

Treasure Island itself is an artificial island with a rich history, created for the 1939 Golden Gate International Exposition. Beyond the challenging climb, the island offers the easy 1.7-mile Perimeter Trail, perfect for a relaxed spin with stunning viewpoints of the bay and Angel Island. This route combines iconic Bay Area landmarks with a significant physical challenge, making it a memorable ride for those seeking both scenery and a workout.
