Embark on the San Francisco Bay & Carquinez Strait Trails loop, a difficult touring bicycle route that challenges you with 27.5 miles (44.3 km) and a significant 1698 feet (517 metres) of elevation gain. This ride, estimated to take around 3 hours and 7 minutes, offers dynamic views where the San Francisco Bay meets the Sacramento-San Joaquin River Delta. You'll cycle past marine scenery with cargo ships and tankers, enjoying sweeping vistas from higher points, including distant views of Mt. Diablo, as you navigate varied terrain.
When planning your visit, be aware that some sections, particularly between Crockett and Port Costa on Carquinez Scenic Drive, can be narrow with limited bike lanes and moderate traffic, especially on weekends. If you plan to tackle segments with natural surfaces, a bicycle with wider tires is recommended to handle gravel or dirt. This route is part of the larger San Francisco Bay Trail, but some gaps in continuous bike lanes exist in areas like Benicia, so prepare for varied road conditions.
This loop takes you through charming historic communities such as Port Costa, often described as a "tiny town that history forgot," offering a glimpse into the region's past. You will also cross the impressive Carquinez Bridge, a notable landmark. Keep an eye out for abundant wildlife along the way and the active railroad line that runs parallel to the water's edge, adding to the unique character of this challenging ride.
