Chikamin Creek trail 1534 starts at bottom of 1510 Chikamin Tie and the start of Minnow Ridge. You'll enter and exit 5 large drainages. Each has fun descents and steep re-climbs.
After the last one, start one of the best descents in Washington. After a short steep grade there's 20 minutes of left-right-left at perfect grades and virtually no pedaling...until the very end where a short steep climb returns you to the parking lot. Low moto use.
