This virtual multi-geocache brings you to little-known places on the refuge throughout south San Francisco Bay. Once all the questions have been answered, bring the answer sheet to the Refuge Visitor Center in Fremont to receive the last digit of the combination to the cache box. Open the box to sign the log, take an item from the box, and then leave an item in the box. Download the coordinates (pdf)
