Summit Trail | Gray Butte Trail Shuttle: 10.3 miles from the Welcome Center to Skull Hollow Campground
Biking with friends and can do a shuttle after the Summit Trail Loop? Go out of the park onto BLM land on the Gray Butte Trail. Joining the Cole Trail takes you to the Skull Hollow Campground. Camping there? Do this in reverse.
Intermediate single track with some steep upward pushes, exposed drop-offs to easy single track. Requires a shuttle from the Cole trail head by the Skull Hollow Campground.
NOTE: CHECK FOR MUDDY CONDITIONS FIRST
Gray Butte is notorious for turning into a thick mud bath after a heavy rain or snow melt, even in this area. Preserve the trail and wait for another day.
Going the same way as the Summit Trail Loop, continue straight at the summit junction on to the moderate single track Gray Butte Trail on BLM land.
Follow it for as it winds past the west side of Sherwood Canyon to the north side of Gray Butte.Get on the Cole Trail until it ends at Skull Hollow Campground. Then shuttle or bike back to the park in 8 miles.
A great way to get in 20+ miles if you don’t mind the push back up the Gray and Cole Butte Trails is to go back ALL the way you came.
Less if you complete the original Summit loop and go down Burma Road Trail to Wolf Tree Trail, to the bridge and back to the Overlook.
