Trails in the Yacolt Burn State Forest are generally open year round but require the use of a Discover Pass. The area and trails are remote and there is extremely poor cell service make sure your party is properly equipped. Most trails are multi-use, expect traffic in both directions and be prepared to yield.
Accessed by making the climb up Road L1510. The trail begins next to the north corner of the cell tower. Follow the ordinary dirt road downwards for roughly a mile until it crosses a loose shale field alternatively take the Cold Creek Trail Spur for a singletrack start. Although the shale field is short (~400') the rocks are large and shift unpredictably. A picnic table on the north edge of the shale field provides good views and a place to regroup.
Next the trail heads into the trees for broad sweeping descents linking corner to corner. These fun bomber sections are intermittently dotted with roots and rocks including an optional steep tech section right after the shale field that bypasses the first switchback. The tech begins to fade and more berms pop-up towards the end of the tree section.
Exiting the trees bring riders to a clear cutting with loads of deep berms and the occasional booter. This section of clear cut includes two gravel crossing, the second of which continues along the Cold Creek Trail. However, this section of trail is closed due to a fatigued bridge crossing. Instead, take the detour to the right onto Murphy's Grade
leads riders on a wide track for just under a mile until it connects back into the Cold Creek Trail. From there the Cold Creek Trail continues with over a mile of rolling elevation, drops, kickers, and a chunky rock garden near the end. Keep an eye-out as the trail joins Thrillium
just before the parking area.
