Lovely trail! The waterfalls are spectacular, and the hike itself overlooked the river for most of the way. Majestic trees, berries, and crystal clear waters. There was a fair amount of toilet paper and other litter along the trail, and the path was eroded in some places, especially along the top of the cliffs. Beware if nervous with heights. Hiked a little more than six miles total from the lower falls to the upper falls.

8am start from crab creek. only car in the parking area. a little overgrown at the beginning, but not an issue afterwards. lower falls were nice to walk out to, the rope to descend and ascend is reliable.

trail is easy to follow and in good condition, nice hike. I imagine it must get busy on weekends

Road to the Lewis River Recreational area is still rough in a few places but passable, multiple signs at the Lower Falls trailhead remind visitors of the the current permit requirements. Pit toilets are open, well-maintained and stocked. I started from my site at the Lower Falls Campground just before 8:30am to hike Lower Falls to the Upper Falls viewpoint. At that time, there were no cars in the day use lot for Lower Falls, and no one on trail, enjoyed the view of the Lower Falls with my morning coffee before heading up the trail. Spent a lovely morning hiking to the Middle Falls and then Upper Falls viewpoint, seeing absolutely no one on my hike until nearly 11am after spending nearly a half hour to myself enjoying a snack with the spectacular view of the Upper falls. Trail is in good condition, spur to the Middle Falls viewpoint is muddy and eroded in a few places but passible, trail from Middle Falls to the Upper Falls viewpoint also has a few muddy spots and a couple downed trees that require a step over or duck under. There are lots of access points to the river especially near the lower falls and campground. 

All in all, a great day on trail, fantastic forests, stunning waterfalls, lots of birds, squirrels and a few little snake friends. Happy Hiking!

If you're coming from Seattle, it's a looooong drive for a day hike, so consider an overnight stay in Woodland, Kalama, Astoria, or at the Lower Falls Campground (which only takes reservations, will probably get booked up pretty quickly after June 15th, and where all the sites are in a dark forest; not my favorite). However, the Lewis Falls trail begins right at the campground and the Lower Falls themselves are close by, so there's that.

The trail is nicely maintained but it is very high above the river; you won't be able to access it until Middle Falls and Upper Falls. The WTA description does not include the fact that the trail is blocked about a mile and a half in, so there is a detour that takes you up to the Middle Falls parking lot and conveniently crosses the Copper Creek Falls before dropping you back down to the main trail. This probably adds a half-mile or more to the overall length.

The Upper Falls are quite wonderful and well worth the long drive and the 5-mile roundtrip hike (or you can park closer), but maybe consider doing other activities in the area. We returned via a two hour drive and overnight stay in Astoria, with its unique history as the first permanent settlement west of the Rockies, its beautiful houses and steep streets, its cozy coffeehouses and at least two great breweries: Fort George and the Astoria Brewery.

Road has been "repaired"!  The road is still rough in the one section about 2.5 before you reach the Lower Lewis River Falls campground and day use area but passable for all vehicles. 

The trail is in great condition with only one blowdown still intact.  This trail offers a mostly shaded walk from the lower falls, passing the middle falls, and all of the way to the upper falls.  Mild elevation ups and downs on a mostly flat trail is a delight except for a few short sections.  Do yourself a favor and continue to the bottom of the upper falls if possible.
