Hey Paul!
Easy enough to find: search the sat map for The Old Tripp Store (Named for the post-master/chemist/dentist/store owner Dr. R.O. Tripp. He catered to the loggers in the area, sadly to my thinking logging the Redwoods out...), located on King's Mountain Rd. and Tripp Rd. Follow Tripp Rd. about 1/2 mile to Summit Springs Rd., 1/4 mile past Tripp Ct. (where I grew up, second house up on the right). Across from Summit Springs Rd. is the estate. It reaches all the way over to the corner of King's Mt. Rd. and Woodside Rd. The mansion is/was easily visible from that spot. The garage is about 1/2 way to Tripp Ct., with the theater just that way from Summit Springs. The main entrance is over at the King's Mt. Rd/Woodside Rd. intersection, actually, just about 50' up King's Mt. from there.
Just a little side note: The first house on the right past Tripp Ct. was the house of a young lady, and lady she truly was, name Poly Moore. We walked home from the grade school down on Woodside Rd. many many times. Wonderful girl! Going up Tripp Ct., the second house on the left was the house of the Chairman of Bank of America. Great guy, name of Bill Pfifle (fie-flee). My father and I cut the huge oak down that was right in the middle of his driveway, hence the big empty spot. Kept us in wood for a couple years!
I used to spend a lot of my time walking in amongst the redwoods that are no longer, all around The Mounted Patrol Grounds which adjoin my parent's property on the back, although the state park up King's Mt., named Huddart Park, who's back entrance, only for horse riders (they say!) is across from the Mounted Patrol Grounds Main entrance just up from the Tripp Store. I spent a lot of time over there of an evening, as that's where the Girl Scout troops would meet.

I figured, if they were gonna come to me...
The patio around the Tripp Store was a wonderful, dry place to wait for the bus, of a morning. As long as we respected the store (no spray paint, carving hearts with initials, etc in the wooden walls and so on) they would let us all stand under the roof if it was raining.
Have fun! Enjoy your look around. When I want to I just look inside...
By the by, when I looked, back in '06, a bare dirt, no services, no electric, water etc etc 1/4 acre lot's price in Woodside? $1
million.

Just a little over my price range! That's why I live in Oregon. Close as I can afford
