MITCNC - Berkeley Three Bears (Intermediate)

Cycling Route

22.1 mi
1,782 ft
The Three Bears Loop is the gold standard loop of the East Bay. A picturesque ride of modest duration, this route takes you along smooth roads through the green hills of Berkeley. Cyclists are able to admire both the San Pablo and Briones Reservoirs while ascending Mama Bear, Papa Bear, and Baby Bear, all relatively short and pleasant climbs. With secluded views and close proximity to both Berkeley and Oakland, the Three Bears Loop is both convenient and enjoyable. If you would like to extend your ride and add a bit more climbing, continue on to Wildcat Canyon and El Toyonal.
