I'm going to head out tonight (after work, hence the late departure) on my bike and stow in at Golden Ears for the night. Apparently the regular campground is unusually full. If I wind up outta luck for a proper spot, how advisable is it to continue on to the east canyon trail and hide out in the forest (no trace camping, of course)?

I'm riding a hard tail with road tires. It manages gravel trail alright, but couldn't do roots and river rock. Also, I might only have about an hour of daylight left by the time I get to the trailhead.

If none of that is feasible, anybody know of an alternate spot in the park?

Thanks in advance.
