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.  

We did this hike as a giant out-and-back for all 3 waterfalls with our dog on a sunny Saturday and it was so lovely. We started our hike from the Crab Creek trailhead, which is different from the starting point on WTA/AllTrails. The Crab Creek TH is a very short distance after a brief hilly gravel road section (that I imagine you would need AWD or 4WD for btw) once the pavement ends. From Crab Creek TH, access Lewis River Trail #31 and in 1.5 miles you’ll reach the Lower Lewis River Falls. Another 1.5 miles further on you’ll start to see signage for the Middle Falls. You’ll come across a small parking lot- just keep going through that to your right and you’ll see the trail to continue on to Middle. Middle falls is cool but more known for it being a slip n slide in the summertime. 
Keep going and about 5 miles in at this point, we reached the base of the Upper Falls which we really enjoyed. We stopped here for lunch before the final stretch to the top of the Upper Falls. This area is very small with little fencing/barriers, in other words this is a dangerous spot that I would be very wary of bringing children to- don’t even think about it if it’s rainy and slippery! At this point we turned around to head all the way back to the trailhead. 

Total distance: 10.2 miles; Total hiking time: 5 hours: Total elapsed time: just shy of 7 hours which includes a loooooong sunny lunch break and lots of photo ops 

What a gorgeous day at the falls! This is the earliest I've been there, and they are running full. The 31 trail obstructions I encountered last May have all been cleared. There's one new one, easily crossed, and one that still has to be ducked under. And last year's impassible trail to the top of upper falls (which is my favorite) is clear, and well worth the climb.

Ahead of arrival: the facilities are still locked. The one at Eagle Cliffs is open and clean. There is one tricky section of road, an unpaved bit prone to washouts. 10mph is optimistic. Maybe a low clearance car would bump a bit, I don't know.

Trillium are blooming, but not vanilla leaf yet. Not mentioned in the trail description is the rerouted trail before coming to middle falls (I think it's been that way for a good while). The detour takes you through the middle falls parking area, and passes Copper Creek Falls, so no side trip required. I returned from the parking area on the road, not knowing what the distance differential was, but remembering being exhausted last year (probably from navigating the blow down). It's 7/10ths mile, compared to 1.5 miles.

I arrived at 8:30 and saw zero people until the way back (three hours later), then two couples, each with a dog, and a hiking club of 14. Go before June 15, when you'll need a parking reservation!
