Scenic Road from Big Pine, CA to Schulman Grove, home to several over 4,000 year old Bristlecone Pines. Road is twisty with several dips providing a roller coaster effect.
The Ancient Bristlecone Pine Forest is home to the oldest trees in the world, several over 4,000 years old. The drive from Big Pine is paved, twisty and dippy, and solitary. Take 168 out of Big Pine and then take a left on White Mountain road. Total mileage one way is about 23 miles. The visitor center at Schulman Grove at over 10,000 feet elevation is open in summer, with interperative programs, gifts, and information about the trees. Several self guided trails allow you to explore the forest. There is a nice short vista hike along White Mountain Road that gives you a pretty good 360 view of the surrounding high desert areas and down into Big Pine and Bishop. The trees are the stars as their twisty, gnarled trunks show the thousands of years of wear and tear they've survived. Takes about 2 hours RT if you get out and hike one of the Schulman Grove trails. There is a 4x4 road to Schulman out of Bishop, but not maintained and "iffy." Winter/spring of 2016 has been harsh on the road with lots of runoff. Although the dirt road is shorter, the paved road will be quicker and much less wear and tear. Check out this drive from Big Pine.
I did this from top to bottom on a larger size adventure bike, not necessarily a dirt bike. I found it to be moderately difficult for an adventure bike to handle. Lots of climate zones you'll pass through on the way down. Lots of water crossings but all were shallow and not a problem.
