Two Oregon State Parks bookend this awesome gravel grinder! Start at Collier Park’s Day Use area near Spring Creek. Take Rd. 390 just past the Horse Corrals for approximately 2 miles then veer left on Rd. 6214 for next 7-8 miles. You eventually run into a main gravel road where you take a left and head down to Jackson Kimball Park. Both parks have camping, bathrooms and the clearest coldest spring water in our area! There are many other route options by taking some of the numerous logging roads in the area.
