If you take #3 , at the top of OLH, you have two choices. Turn right, and follow 35 north about 2 miles to Skylonda. It's wide, fast, and nontechnical. Some traffic, especially on weekends - sports cars and motorcycles. Turn left at the intersection of 84 and 35, and you get a couple miles of pretty gentle descent.

Go straight across at OLH and 35, (after listening carefully for sports cars and motorcycles!) and you descend West OLH, which is narrow, a lot more technical, next to zero traffic, and considerably more scenic. It deposits you about 3 miles farther down 84 from Skylonda, BUT it comes out at a blind curve on 84. My advice would be to turn right and head up the road a could hundred feet till you can see clearly in both directions before swinging a U-turn and heading back West.

Descending 84 from there can be lots of fun, till you get to like the last 5 or so miles, which are pretty flat, and if the wind is blowing from the West (and when isn't it?), a bit of a slog.

There's a nice little store at 84 and Stage Road in San Gregorio, where you can stop and refuel. South of San Gregorio, my experience ends. I've only ever headed North to Tunitas Creek and back over the hill.
