Started our journey at the lower falls campground and made our way about 2 miles in when the trail was detoured due to a washout. The trail that continued up led us to a beautiful bridge and falls (so it was totally worth it) then we reach the middle falls. The river was raging as we made it to the upper falls. We continued up the steep trail to the viewpoint overlooking the upper falls which I highly recommend doing. Most people seem to stop at the upper falls and don't go that extra bit for an amazing view. We managed to run into 7 people kayaking the river and watched them navigate the falls successfully, well, for the most part. One guy lost his kayak and on the way down the falls. All things considered, it was awesome. Just watch out for trees down on the trail and if you bring kids, make sure they are aware of the abrupt drop-offs that anyone could easily plummet to their death from.

FS Road 90 is a little tough in spots past the junction with Curly Creek road. down to one lane in spots due to trees and rocks. The gravel section would be a challenge on a motorcycle. But any car with normal clearance would make it.

We opted to do the short hike (.5 mile round trip) to the lower falls from the campground and then drive up to middle falls to do the middle to upper loop. This also turns an eight mile round trip to a four mile round trip hike and allows you to see all three falls still. This makes the hike doable with youngsters. 

The trail is beautiful. Old growth trees, high cliffs and the raging Lewis River and falls. There are a couple of spots leading up to the upper falls that you must watch little ones because of fall hazards, but this should generally be a great family hike.
