Last one! Parked at the Manaticut Point trailhead off of Crescent Rd and took the yellow/black trail to the yellow trail up to Manaticut Point. From there continued on blue/white for a few miles to the summit power lines. Just before the summit there was a washed out part of the trail so I bushwhacked around. Once at the summit I doubled back and took the trail down to Lake Sonoma and looped back to the car. It was a nice hike to end this challenge on.
