Nope...sorry. I've ridden the Tour of the Unknown Coast a couple of times, but I wouldn't recommend it solo. It's a very remote area, and the back roads are getting worse every year because the counties have no money for repairs. A friend of mine was seriously injured on this year's TUC, likely due to the poor road surface on one of the downhill sections.

But if you're not into extreme, just riding through the redwood groves (e.g., Avenue of the Giants), is pretty amazing. And national parks are great for riding, because car drivers expect to see cyclists, and give them room. I've had shouts of "Allez!" when climbing the summit road in Mt. Lassen National Park.
