I did the shorter version of the hike from the North trailhead. Fantastic hike. Beautiful walk through lush forest with some old-growth trees. Waterfall is amazing. Coordinates for North trailhead parking lot: 47.07794,-121.58567.

Bugs: Didn't notice any bugs while walking through the forest, but there were quite a few mosquitos up at the falls.
Road: Some large potholes on the gravel road after turning off Chinook Pass Hwy. It's not very far on the gravel road so most cars should be fine if you're careful.
Parking lot: Lot is pretty small. It was fine on a Thursday but might get busy on weekends.
Bathroom: Yes.

This trail was frustrating.  We found the trailhead quite easily and were the first ones in the parking lot. We should have known the trail was going to be difficult from the beginning, not in ability but from a marking standpoint.  There are lots of little off-shoots to camp sites and it was very confusing to know which path was the "actual" trail.  The walk through the woods was nice, but we became increasing frustrated at the lack of markings and have to continually double back to take a different route.  At the end of the day we walked about 6 miles but never did find the falls.  The area was great, and we plan to revisit, but the trail needs some visible markings to let you know you're on the right path.

We did the longer version of the hike, starting at the southern end and hiking downstream. Very easy trail, except for the last scramble up to the falls, which is very worth it, but pretty much a goat trail straight up the hill.

A mile or so in you will come to a Y that has a post but no sign attached, so it’s unclear which branch to take. To get to the falls, take the lower branch on the right. As you pass the post you’ll see the word “Falls” written on the right side, but it’s easy to miss.

Road out to trailhead off FR 73 has some pretty good pot holes; not an issue for my GMC Denali, but those in small commuter cars should know about it. Trail was excellent, easy even for me recovering from spine injury. I went with my 24yr old daughter and both my puppies who are 11 month old Yakutian Laika and a 14 week White Swiss Shepherd/Berger Blanc Suisse, neither had any issues,  only 1 spot we had to pick up the 14 week old to help him down a big step down, but on the way back he did it all on his own. The waterfall is about 2.1 miles from trailhead and worth it,  it's stunning.  Overall, trail is about 4.3 miles and only 113 elevation gain according to my app. Only a couple mosquitoes the whole trail. Most people also wore masks when they passed others on the trail. An excellent Mother's day!

I completed a 13.1 mile loop that included Snoquera and Skookum Falls. Starting at the north Skookum flats trailhead, I hiked clockwise, see the attached caltopo map. There is only 1 blowdown that presents a little challenge, it is on the southern part of the Snoquera Falls portion, there is a steepish boot path going around it, 19 out of 20 people will not have an issue with this (but, I was glad that I had poles). Crossing Snoquera Creek by the falls was not difficult, my boots got wet in a few places, an inch above the sole was the deepest and that was just for a moment. There are a few spots on the northern portion of the Snoquera Falls loop that are quite rocky, especially the chute where there was a landslide at some point, but all of these were easy to cross, they just took some care with boot placement and going slowly. I was glad that I had poles and that I was going uphill.  Other than those short sections, the tread on this route is quite good and fast.    

A description of the route:
- From the parking lot take FS road 73 over the White River

- immediately after the bridge, on the right/south is the signed Dalles River Trail, this runs for about .6 mile and comes out at the Dalles Campground near a huge stump and fallen tree

- at the campground veer to the left to take the road that runs closest to 410, take that until it exits onto HWY 410

- directly across 410 is FS road 7150, cross 410 and hike on residential FS 7150, it goes east and rises for a bit, then turns south/right and runs for about .5 mile before turning right/west and going down to meet 410. There are some very quaint cabins on this road and it is a pleasant walk.

- here you have to walk along 410 for 2/3 mile. Except for 150 feet at the end, the left/east side of the road has a dirt area outside of the paved shoulder. While there were many cars heading south on the other side of the road, only 1 car passed me heading north on the side of the road where I was walking. An added plus, this portion of the road contains the pullout for the Skookum Falls Viewpoint.  

- after 2/3 of a mile on 410 you can see the trail sign for The Palisades and White River trails on the east/left, take that

- take the Palisades to the White River, to the Snoquera Falls Loop (up and over and down), to the White River, take the White River trail south until you hit the exit onto 410

- right across 410 is an old road, follow the road for .2 mile, past 2 blowdowns, and it comes out on the Buck Creek Road at the bridge over the White River.

- after you cross the bridge, the Skookum Flats Trail is almost immediately on your right/north, take that back to your car
