Flagline Trail is generally closed until Aug 15 to protect elk calving grounds.
Access to the desirable Flagline Trail starts here (accessed from Dutchman Sno-Park).
It's the beginning of the loop around Tumalo Mountain. Generally up, with lots and lots of tight, curvy turns, often with roots, and rock obstacles. All fully rideable though. Look West (left) and every so often you get a spectacular view of Brokn Top mountain.
At the end of Flagline Access trail, you can jump on Flagline (duh!) for a fully fun downhill.
