Santa Cruz Facilities From Northern California

From Highway 17 take the “Mount Hermon Road” exit at Scotts Valley. If coming from the north, turn right at the light onto Mount Hermon Road. Once on Mount Hermon Road, proceed 3.5 miles through Scotts Valley to the "T" and signal light at Graham Hill Road. Turn left onto Graham Hill Road, then follow the directions below to the specific facility.

Santa Cruz Facilities From Southern California

Take US 101 North to Salinas. Exit at Market Street and take Highway 183 West toward Santa Cruz. At Castroville take US 1 North to Santa Cruz. At Santa Cruz, take Highway 17 North toward San Jose. Exit at Scotts Valley at “Mount Hermon Road.” Proceed through Scotts Valley on Mount Hermon Road 3.5 miles to the "T" and signal light at Graham Hill Road.

To Conference Center

After turning left at Graham Hill Road, turn left onto Conference Drive, which takes you into the Conference Center. The Administration Building is just past the post office on the right. The Mount Hermon Bookshop is directly across the street.

The street address for GPS use is 37 Conference Drive, Mount Hermon, CA 95041, and the GPS coordinates of the Post Office parking lot are 37° 3'4.63"N, 122° 3'29.12"W. Some online and GPS mapping systems incorrectly place us inside "Felton, CA 95018" so if you have trouble, you might try that. One mapping service still shows directions from "Mt Hermon Rd" to a left on Conference Drive, that road has been closed since the 1970's, you must continue on "Mt Hermon Rd" to the end, left on Graham Hill Rd  then make the left on to Conference Drive.

To Redwood Camp
From the signal light at Graham Hill Road go 2 blocks left. Turn left on Zayante Road. The Redwood Camp gate is approximately 1/4 mile on the right. The physical address for mapping purposes is 6496 East Zayante Rd, Felton, CA  95018. Please do not send mail to that address.

To Ponderosa Lodge(Location of most Outdoor Science conferences)
From the signal light at Graham Hill Road, turn left and proceed a half mile past the turn-off for Conference Drive. Turn left at the Ponderosa Lodge sign. If you pass the Probation Center on your left, you’ve gone too far!


Directions to Kidder Creek

Google Map

Kidder Creek is located two hours northwest of Redding, about one hour south of the California-Oregon border, just off I-5, in a heavenly place called the Scott Valley. To drive to Kidder Creek, follow I-5 to Yreka and take the Hwy. 3 exit toward Fort Jones/Etna (south). If you are heading northbound on I-5, this is the first exit in Yreka. If you are southbound on I-5, this is the last exit in Yreka (3rd exit). On Hwy. 3 head southwest over Forest Mountain and then through Fort Jones. Go 6 more miles. Just past Greenview (don't blink or you'll miss the gas station), cross over the Kidder Creek Bridge (not a big one), and then immediately turn right on South Kidder Creek Road.
