Getting There

The waterfall is unnamed, which is surprising considering its height and beauty. The trail up to the falls is an easy hike, but once at the falls, if you want to get down to the base of the falls, there is a bit of a scramble down (and up).

No parking permit required. No toilet available. Privy available at the Washington State Department of Natural Resources campground 2.8 miles east.

Beautiful trail close to the river. Can be quite muddy and busy. Make sure to pack enough water and a lunch to enjoy by the water.

Really enjoyed this trail with our little one in a baby carrier. Super easy hike to the first falls, but steep down to the base. We got to the trailhead around 10:30am and had the waterfalls to ourselves but around noon we started to see at least 4-5 families. Definitely earlier the better for a nice relaxing time. Bring a snack and enjoy it at the base of the waterfall.

This was the least trafficked trail we have done this summer. Saw less than a dozen people the whole time on the trail. We only did about 3-4 miles, depending on which device (Apple Watch said 3 miles, alltrails on iPhone said 4 ) . We went as far as the (first?) falls, down to the water, back up to the trail and then back to the car. We hiked with 3 kids, one one my back half of the time, and it was fine for all of us. There are some spots where the slope off the of the side of the trail gets super steep, so definitely keep little ones close at hand. Mostly shady. Water is cold!! Couldn’t swim, but we enjoyed splashing and skipping rocks. Very family friendly trail.

What a fantastic hike. We got to the trailhead about 1030, about 5 cars in the lot. The road was honestly not too bad, plenty of cars that made it. Just go slow. The main waterfall is only about a mile or so in and if you go about another mile there is a smaller one. There is fallen trees on the trail to go over and under to make things a little interesting. Bring bugspray though! Didn't do the entire hike but would like to go back to do so. Got back to the trail at 130 and it was packed and overflowing down the road. Note: our planet is so beautiful and this trail is a perfect example. Pack OUT what you pack IN. There was trash all over near the falls.

HikingGreat!

This is a beautiful hike. The road up to the trailhead is bumpy. We managed with a Subaru Outback but a truck/SUV would have been better. The hike to the falls is short maybe 1.5 miles or so. We didn’t do the full trail but plan to go again in the future!

We loved this beautiful wilderness trail. Spectacular waterfalls, rushing river, amazing old-growth firs. Brushy in places and some of the trees over the trail were challenging with our backpacks. The bugs were out, but we slathered up with deet and they didn't bother us much. A few muddy spots but no problem to get through. Overall one of our favorite hikes so far!

HikingGreat!

The last 3.5 miles of the drive will test your willingness to hike. The road is a gravel dirt road with some major pot holes. Parking is limited but you can find a spot of the side of the road. Lots of shade leading up to the twin falls. Semi difficult to get to the falls, but can be done with a child in an Osprey pack. Room at the waterfalls to sit and snack or get in the water. Not crowded by any means. Good luck when driving back out that 1.5 land road.

Nice shady walk in the woods on a hot day. No major trail obstacles, just a bit of mud here and there, a few manageable blow downs and moderate bugs.

A few months ago the road was barely passable in my Ford Ranger, but it has since undergone some maintenance and is in near perfect condition. Now any vehicle should be able to make it up the gravel road with no problems, there are still a few potholes but they are still working on that, and they are all avoidable. As far as the trail itself, it is a nice walk through the woods. The falls are maybe a mile or so in, which makes them an easy destination for families and the like. If you wish to do the full trail, just keep following the trail to where it ends. At the end you can go down to the river and sit on the edge or climb around on some rocks, and then head back. As far as conditions go, there are a few fallen trees to climb over throughout the trail and it does get a little overgrown in spots the further you go along, but nothing too bad.

I’m not sure why this trail is rated as moderate, definitely more on the easy side. Only a few inclines, but not difficult at all. This is a great trail for families up to the double waterfalls. Beyond that it’s mostly just a hike through the woods, not a whole lot to see, although really beautiful, and the roar of the river is amazing. Almost the entire trail is shaded, so that made the hike nice as it was in the 80’s today. The trail up to the double falls is clear, and easy to navigate. A few downed trees, but easy to get over. And a bit rocky in some areas, but again, easy to navigate. Farther up the trail it gets quite overgrown, with more downed trees, a bit more rocky, and some water running over the trail making it a tad muddy. I would recommend hiking boots, or at least a good trail shoe. I don’t advise sandals or tennis shoes. It was pretty buggy, but not bad enough I felt the need to break out my bug spray. Mostly flies. Didn’t notice any mosquitos. The dirt road up is quite long, but the potholes were not nearly as bad as I thought they’d be based on other reviews. Anyone in a compact car could make it up no problem, just take it slow. Get there early. We arrived at 9:30am, and there were only a few other cars in the parking area. We only passed three people as we headed up. Coming down, around 12:45pm we started seeing LOTS of people. And when we got down the the lot, around 1pm, it was completely packed. Happy Hiking! Enjoy :)

The potholes on the drive up are no joke. Got to the trail around 8:50, and there were only 2 other cars in the parking lot. Beautiful relatively easy hike, with some awesome fallen trees to scramble over and under. A few parts of the trail are very overgrown so it feels like you’re walking through bushes. Tons of mosquitos so bring bug spray. The waterfalls are spectacular and the river is beautiful! We got back to the car around 1pm and the lot was totally full. Come early to avoid a crowded trail
