From Santa Cruz/Felton:

Take Highway 9 Northbound to Ben Lomond.  Approx. 1.7 miles North of Felton you will see a light at Glen Arbor Road; this is a right turn only that immediately goes over a big bridge over the San Lorenzo River.  KEEP GOING past this, continuing on Highway 9 to Ben Lomond.  There will be a second light, also at Glen Arbor Rd. (it loops around); TURN RIGHT.  On your next right corner you will see St. Andrew’s. Turn right on Riverside Ave., then left into our parking lot.

From Hwy. 17 Southbound:

Take the Scotts Valley Mt. Hermon Road exit; turn right.  Follow Mt. Hermon Road through Scotts Valley, through a couple of miles of open area with quarries on both sides, and you’ll drop down into Felton.  At the bottom there will be a Safeway shopping center on your left; turn right at the light, onto Graham Hill Road.  About a block up you’ll see Highway 9 – turn right (Northbound) and proceed as above.

From Hwy. 9 North (Boulder Creek):

Follow Highway 9 Southbound until you enter Ben Lomond.  There is only one stop light – turn LEFT onto Glen Arbor Road.  On your next right corner you will see St. Andrew’s. Turn right on Riverside Ave., then left into our parking lot.

DO NOT TRUST DIRECTIONS FROM MAPQUEST – THEY ARE INCORRECT!!!
As you can see on the map below they show St. Andrew's at the bottom of Riverside Ave. at Wente St.  This is incorrect; the star should be right where the 'R' in Riverside is…
