R on Pinehurst. The L goes through some redwoods, towards Redwood Road. That's a different trip, though you can get up to skyline that way too.
There used to be streetcar/railroad service here, with a tunnel through the hill over to Shepherd Canyon Rd, last used in 1957. The entrance was about here on this side. When you go up the climb here, you'll know why they tunnelled through.
