The Trip Planner at 511.org is a great resource for getting around SF Bay. Golden Gate Transit Buses and the Blue and Gold Ferry provide service to downtown Tiburon. However, you will need to arrange to be picked up, take a taxi, ride a bicycle or walk the remaining 2.4 miles along Paradise Drive to reach the campus. From downtown Tiburon, you will first encounter the 3150 Paradise Drive gate on your right, then the 3152 gate will be 0.5 miles farther on the right.
