This is a loop, beginning and ending at the Crab Creek Trailhead of the Lewis River Trail, #31. The Crab Creek trailhead is on Forest Road 90, 13 miles past the junction with FR 25, 100 yards north of a bridge across the Lewis River. (The 13th mile currently includes 0.6 mile of rough and potholed dirt and rock road, due to an earlier washout.) The trailhead sign reads LEWIS RIVER TRAIL #31. Parking is along the shoulder of the road.
From the trailhead, we set out west, climbing at first, then dropping sharply to cross Cussed Hollow Creek on a sturdy bridge. At 0.5 miles is the junction with the Bluff Trail, #24 (as it is known on signs and the Forest Service web site). The Bluff Trail is 2.7 miles long, gaining 1800 feet. 1000 feet of that gain occurs during a one mile grind in the middle. The flora is typical for the elevation: ferns, salal, berry vines, and lots of vanilla leaf. There are no camps, no views, no water, and (oddly) no bluff! There is water at the upper terminus, where Spencer Creek crosses FR 93.
From here we walked north on FR 93 about a mile to Spencer Meadow, then headed south on Trail #30 to Spencer Butte. Unlike Trail #24, this trail was badly rutted from motorcycle use. You need strong ankles and a contorted gait to make decent time hiking it. At 1.25 miles, we were treated to a view of Mt. Adams on our left. Then at 1.5 miles, we reached the high point at 4247 feet and the concrete foundation piers of the former Spencer Butte lookout. There were just a few patches of snow. Unfortunately, there were no views. The trees had grown tall enough to block all but a glimpse of Mt. St. Helens or Mt. Adams.
We returned to FR 93 and followed it a very short distance to the upper trailhead of the Cussed Hollow Trail #19. This too was rutted, at first not so badly. But halfway along, the ruts were so deep as to make me wonder whether motorcycle gear shifts could get bumped inadvertently. I later encountered a rider and asked him. He said, "I know exactly which part of the trail you're talking about. The ruts are so deep, the trail has become unrideable". Sadly, those same ruts make it unpleasant for hikers, and treacherous when wet.
At 3.3 miles, Trail #19 ended at a junction with the Wright Meadow Trail #80. We followed this broad trail the remaining 0.6 mile back to FR 90, crossed the road, and continued until meeting the main Lewis River Trail #31. We followed this outstanding trail the last 2.3 miles to complete the loop, stopping in the middle to admire the Lower Lewis River Falls. Total mileage was estimated at 13.8. Most was in forest, and therefore shaded.
