From the Metro Center in Downtown Santa Cruz:
Take any route 69 bus. These all go to the Capitola Mall, and the 69 A, N and W all go from the Mall down 41st Ave. (The Mall is just off the bottom of the map above on 41st Ave.) Get off right before the Hwy 1 South on-ramp. There is a stop right in front of the KFC on 41st Ave. From there it’s a five-minute walk: cross 41st Ave. at the Circle K/76 Station, and go down Gross Road. Go to the right at the 4-way stop and you’ll be on Soquel Ave./Frontage Road. We are down about 800 yards on the left, after you pass the Honda motorcycle dealership.

(From the University of Santa Cruz, first take any University bus to the downtown Metro Center.)
