Sun Mountain Resort features 80 miles of hiking trails near Winthrop, WA.
About 1 mile East of Winthrop on highway 2 turn SW onto Twin Lakes rd, 3 miles later take a right on Patterson Lk rd and follow it 6 miles to the resort at the end. If you are only going there to ride and do not need to go up to the resort a better parking area is 1 mile earlier at the north end of Patterson lake and is marked Chickadee Trailhead Parking, most of the MTB trails can be easily accessed from here, there is also restrooms and bulletin board/trail map.<br /><br />
