From Hwy 120 out of Stockton off Hwy 99 to Hwy 26 all the way to Hwy 88 and Pioneer
This route takes you from the Valley up into the Seirra foothills and beyond. Lots of twisties with trees from pine to redwood. Views are wonderfull. During the winter months you can take hwy 26 up to Hwy 88 and turn right until you hit the snow at around 4,000 foot level. Along the way you will cross two rivers and cruise through only a very few small towns.
Lots of curves going both up hil and down. Little or no gravel or debris in the roadway but be careful of the Deer and wildife in the area
Been up this way many times. Good ride. There's fuel and food in Lockeford east of Lodi including Lockeford Meat and Sausage where there's often a line outside the store. Not much after that until Jackson. Good warning about deer.
