Clarke Butte to Jones Tr3472 could be a CW or CCW loop, or an OAB on Jones Tr3472.
Many will find the 1.5mi, 20% Clark Butte Tr3456.1 entirely hike-a-bike.
Some hike-a-bike on this segment pays off with a 6mi Jones Tr3472 descent, so CW may be the best ride.
These two trails are connected at the top by FR1817 and at the bottom by the Fall Creek National Recreation Tr3455, although that trail is indicated to be hiker-only, so please use FR18 instead or take the bike for a 'hike' at that point. To shuttle, use FR1817 as the upper TH, riding to the Bedrock Campground.
Hiking: Fall Creek National Recreation Tr3455 is a generally level hike alongside Fall Creek, with a switchback to 1400' just past the Bedrock CG and many exit points along the nearly 15mi route. At Slick Creek there is a small cave and rock outcropping.
Clark Creek Nature Tr3456 includes interpretive signs and botanical variety. Also check out the nearby Johhny Creek Nature Tr3454.
Cowhorn Mountain Tr3458 ascends through a Douglas Fir forest to Little Cowhorn Mountain, and is steep and rough.
