The 2.2mi Oak Ridge Tr688A (~1850') descent contains switchbacks with large loose rocks, erosion and banking, and is not suitable for climbing.
A hike-a-bike to the top, then downhill is certainly an option, but the described CW loop is not much tougher than hiking and includes a Bald Butte climb on Surveyors Ridge Tr688 so adds some variety.
Using FR17 to shuttle to the upper Oak Ridge Tr688A TH is another option, for those seeking some fast vertical descent.
Dog Rvr Tr675 provides a longer descent and easier shuttle.
Directions: Take Smullin rd, which is on the left 1.4mi past the Mt Hood Country Store and just before the Hwy Dept facility. Road to Oak Rdg TH is at the first curve. View Larger Map. No Map?.
