This past weekend 10 bikers/adventurers set out to show that public transit is a viable option for getting out to the Bay Area's amazing parks and open spaces. They took it to the extreme by attempting to ride their bikes up 3 of the highest bike accessible mountains in the Bay Area - Mount Hamilton, Mount Diablo and Mount Tamalpais - in 1 day and only using public transit to transfer between each mountain.
This adventure was put on by Transit and Trails, which is a project of the Bay Area Open Space Council. The site allows users to Find, Plan, and Share outdoor trips via public transit. There are hundreds of trailheads, 20+ hikes and bike rides, and all of the region's campgrounds on the site. Users can find hikes and outdoor recreation opportunities in any part of the region and then plan how to get their on public transit, biking, or driving. Funding for the site is provided by the David and Lucile Packard Foundation, San Francisco Foundation, State Coastal Conservancy, East Bay Regional Park District, Save Mount Diablo, and Sonoma County Agricultural Preservation and Open Space District. Partners include GreenInfo Network, Bay Nature, 511.org, Metropolitan Transportation Commission, and Bay Area Air Quality Management District. Transit and Trails uses Google Maps for the base map and routing.

Using the Transit & Trails site to plan out the bike ride, lengths and how to get from mountain to mountain the group set out on Friday evening from San Francisco (some from Oakland). They camped out at Joseph D. Grant County Park in the foothills of the Mount Hamilton range in order to get an early start on Saturday morning. From San Francisco they took Caltrain and then biked up to Grant park via the very challenging Quimby Road.
Departing at 5:30am on Saturday, June 19 they tackled Mount Hamilton before the crowds showed up. After descending Hamilton they headed over to the Alum Rock VTA Light Rail station which they took to the Great Mall Transit station and transferred to the VTA 180 bus. They took the 180 to Fremont BART, then transferred to the Pittsburg/Bay Point line to Pleasant Hill. Running a few hours late because of a long lunch stop, having to stagger the bus rides because of too many bikes, the group charged up Mount Diablo from the BART station. Two hours later they arrived at the top and after a quick snack and photo break, they sped down Diablo back to BART. For some folks this was the end of their journey as they had only planned on the Double Dip. For a few the adventure continued to Mount Tamalpais for the third and final leg.
After a short ride on BART they arrived at Embarcadero at 6:15pm, just in time to get the last ferry to Sausalito. On the ferry, the rested and refueled before the last leg, Mount Tamalpais. Feeling a bit tired and run down they took a few breaks along the way, but arrived at the top of Tamalpais at 9pm, about 15 hours after they started their journey! They congratulated each other and then headed down the long, cold, dark descent. By 11pm they arrived at the Marin City Transit station, where they picked up the Golden Gate 80 back to San Francisco. Arriving home just before midnight, about 19 hours after they started their expedition.

All in all 110 miles of riding, more than 10,000 feet of elevation gain, and a myriad of transit - Caltrain, VTA light rail and bus, BART, Golden Gate Ferry and Golden Gate Bus.
The team saved 1,138lbs of carbon from being emitted into the air by taking transit over driving! The total cost for transit was about $30/person.
