I've been going on motorcycle rides every weekend since I got my bike in August. Here's a list of the routes I tried out. Since I'm interested only in twisty roads, all these routes have their fair share of winding sections.
All these routes involve these highways - 9 (the Saratoga one), 17 (Santa Cruz), 84 (aka Woodside road), 35 (aka Skyline Boulevard) and 1 (aka Pacific Coastal Highway).
1) Saratoga - Hwy 9 - Big Basin Park; back the same way
Nice route. Hwy 9 has some really winding curves (be prepared for nearly 180 degree high-lean turns). Although after the 35 junction, the road surface deteriorates.
2) Saratoga - Hwy 9 - North (right) on 35, West (left) on 84, South (left) on 1; back the same way
84 is amazing - excellent road surface and 45-50 mph high-lean turns. Hwy 35 richly deserves the Skyline Boulevard moniker. The day I went, the valley was smothered in fog while Skyline itself was clear. It made for an amazing sight - riding on a mountain above a seas of thick clouds.
3) Saratoga - Hwy 9 - South on 17, Santa Cruz, South on 1 till Monterey; back to Santa Cruz, Hwy 9 all the way from Santa Cruz to Saratoga
17 is not much fun. It has a lot of moderate-lean high speed (~ 65mph) turns, I didn't like it so much. Hwy 1 is also boring - it's not twisty enough. The section from Santa Cruz to Monterey is especially disappointing - it's a normal 6 lane highway. The scenery gets real good only after Monterey.
Hwy 9 though is fantastic. Right from Santa Cruz, it's all twisty and the road surface is excellent.
4) El Camino/El Monte - Moody Rd - Page Mill - North (right) on 35, West (left) on 84, North (right) on 1, Half Moon Bay; back the same way
Moody Road is very narrow in parts. Page Mill is tough (especially going downhill). The turns are sharp, narrow and road surface is questionable. Very good for building riding discipline and technique.
5) El Camino/El Monte - Moody Rd - Page Mill - South (left) on 35, left on Pierce road (Mt Winery, Saratoga) - Saratoga Avenue - home
35 continuously offers either fun turns or, in the straight sections, excellent views. Pierce Road is average.
6) 280N, West on 84, North (right) on 1, Half Moon Bay, East (right) on 92, South (right) on 35; East (left) on 84 and 280S back home
The sections of 35 and 84 I hadn't done before proved very good. Just minutes south of 35-92 intersection, there are a couple of vista points from where you can see the entire bay, including the skyline of San Francisco and Oakland, the bridges (Bay and San Mateo) and the hills of Fremont. As usual, 35 is either fun to ride or scenic :-).
I noticed an unusual number of cops in this route. Watch your speed in the straight sections.
7) El Monte Rd, Foothill N, 84W, right onto King's Mountain Road (easy to miss turn), south (left) on 35, west (right) on 84, left on to and continue on Pescadero road, back via pescadero->84->35->page mill->moody
King's is really beautiful. Pristine redwood clumps in the valleys and log cabins by the roadside. Beware of bicyclists though. Pescadero road is quite nice too - it winds all the way to Half Moon Bay, though I turned back at Pescadero. Both King's and Pescadero roads are twisty and a lot of fun to ride.
8) El Monte Rd, Moody Rd, Page Mill Rd, Alpine Rd, left on to Pescadero Creek Rd, turned back at Pescadero, Pescadero Creek Rd, north (left) on 35, east (right) on King's Mountain Road, east (left) on Woodside Rd, 280S, home.
The stretch of Alpine Road from it's intersection with the Portola Rd till the intersection with Pescadero Creek Road is the most beautiful forested stretches I've seen. The huge redwoods covering the mountain side reminded me of "Avenue of Giants" near the national redwood park (California-Oregon border). It was picture postcard perfect - the ground carpeted with fallen leaves, small bridges with moss covered wooden railing, beams of light filtering through the treetops lighting up the motes of dust in the air. As far as the ride is concerned, Alpine Rd is challenging as it is very narrow and has questionable road surface. King's Rd like I had found out earlier is narrow and has many low-speed sharp U-turns.
To do:
Hwy 25, Hwy 9 from Big Basin to Santa Cruz (and other twisties I find on the map!)
