There's a nice view into the West Satsop River gorge from the bridge right before the trailhead, and there's a nice campsite just past it with some views of Spoon Creek above the falls. 

We were only able to see the falls from the upper overlook. The flow is massive and gorgeous. Spray was rocketing back up into the air at the base of the falls. The lower trail ended at the river. I suppose you could wade into the river to keep going, but it's pretty high right now. 

TL;DR - bring water shoes, beware of steep bluffs on either side of the trail, expect passable but poor trail conditions! There is no signage along the roads for Spoon Creek Falls, but the Google Maps trailhead marking is correct. The roads had some passable fallen trees and potholes, so drive slow and consider driving a higher-clearance vehicle. The trail starts downhill and is somewhat steep but very short. Some fallen trees and exposed roots/rocks that may be hard to navigate for little ones. Once the trail spit out onto the river bank, the upriver hike covered gravel and slippery rocks. Definitely bring water shoes for this part, and look for toads along the rocky bluffs! When we visited the pool was very cold and ~4 feet deep in sections. The waterfall was so beautiful and the weather was so warm we ended up spending and hour there. Happy hiking!

Trail a little wet but in good condition. Shoes might get wet getting best view of the falls.

Enjoyable trip with wife, daughter, and grandsons ages 5 & 10. Everyone waded in the creek and had a great time. Spectacular falls and no one else around. Only mosquitoes we saw came out when we got back to the car. Road looked newly graveled/graded to Satsop Center, nice the rest of the way.

Please note that the roads are impassable at a certain point on NF-23. You can get via car to the fork (see image). To your left(N) Satsop center has major fallen trees and is impassable and to your right(S) is where you normally would drive down to Spoon Creek Falls.

We were able to walk about a mile from the fork to Spoon Creek, you will need to traverse maybe 9-10 clusters of fallen trees. I would be careful in any sort of bad weather as it is clear there were many mud slides that occurred. There was a bit of snow on the road but it was manageable in normal shoes, some ice. We also noticed some tracks that appeared to be from a cougar/mountain lion. 

Spoon Creek was beautiful as always.
