Yetiman and I needed a short, easy hike and this one fit the bill. The trail is rife with giant trees, the river is very close by and scenic, and Skookum falls is a worthy destination. We saw awesome moss gardens, a female elk, huge logjams, nice campsites, plus the trees and the falls. The scramble up to the base of the falls is quite long and steep and a little slippery, but well worth the effort.
We started out from the trailhead on the trail, then took the first detour available down to the riverbed. We followed that as far as we could, maybe 1/3 mile, before the river forced us back to the trail. We had to hop over a couple of small stream channels, then found ourselves at a campsite about 3/4 mile up the trail. The trail is mostly flat and is open to mtn bikes, a few of which passed us by politely. They had the right idea, as the trail is perfect for some fun biking. When we got to the falls, we didn't see the sign pointing to the trail up to the falls that is just across the small bridge over the stream. We tried to scramble up the mossy boulders to the falls, but that became almost suicidal due to the slippery steepness involved. We clambered down, crossed the small bridge, and then smacked our foreheads as we saw the sign pointing to the path upwards. Even the path is fairly tough, but doable. There are some excellent viewing spots of the falls up at the top, and some shelter from the fall's spray. We stayed there over an hour enjoying the spectacle and taking pictures. The hike back went quickly, and we got to see the trail section we bypassed on the way in. It was the nicest part, up on a high bank with huge trees and a view of the river below.
I was worried that this hike would be not so great due to the road being right across the river, and the hills beyond the trail being cris-crossed with FS roads going up to Suntop, but none of that is visible or intrudes on the hike. There was a great wilderness feel to the forest and the river, even though it is not wilderness. I also expected crowds on a Sunday, but we saw only three bikers and two hikers in six hours there. The drive took just 90 minutes from Lynnwood.
