filled in hole of the massive rock we moved
Step up that we built a ramp for. Shorter wheelbase can go around quite easily
picture of the steep section, circle is what we removed, to the right another large pointy rock. picture doesn't do the grade justice
pick of washout, standing dowslope which is the way I slid both times
trying to show the grade going in/out
For reference; third gen longbox taco, 2inch lift on 33s

as others have said road heavily degraded and very overgrown. IMO 3 cruxes, initial washout that is off camber and steeper to exit than appears in photos, both up/down began to slide sideways, IMO worst section. Second is a hill that had two large boulders sticking out that looked like they wanted to snag underbelly, we removed one and took a line to the left. Final one is at the end and due to longbox had to go over the rocks W/ a ramp we built. Shorter wheelbase can zigzag this easily. ***key point*** there's a pullout just after first washout, after this there's no more turning around so you're stuck if you can't make it past something so keep that in mind if you felt you were already pushing yourself.

This is the upper crux, choose your line. Not really much harder than anything before it. Nowhere to turn around though so better hope you can make it up
Looking down at the upper crux
Another view down above upper crux
Getting bushy again..
Williamson Lake Trailhead, truck for reference. I wouldn't attempt this road in a stock SUV, you'll want good clearance & tires or you will be beating the piss out of your vehicle on all the rocks
Super rocky & bumpy, may have gotten slightly worse compared to last year but still ok in HC 4x4 for now. The upper crux looks intimidating but was totally fine, I found the narrow off camber spot on Foley Lake FSR sketchier than anything on this road.

No major change from previous reports. Still very rough and bushy. HC 4x4 definitely required. One cross ditch about half way up has possibly gotten worse -- seemed very eroded and quite spicy. But made it to trailhead in my FJ Cruiser without issue.

High clearance 4wd could go a bit up this road but quickly becomes steep with big loose rocks. ATV tracks noted in the snow pretty much to the top though.

Mostly the same condition as Seans report, just covered in a layer of snow. Snow coverage was thin on the road due to tree cover as well as water running down the road. (If it gets well below freezing for a few days I would expect this road to be an ice rink.) After approximately KM 2 there was less water and the snow started to build up. We were able to make it up to the trailhead, but the final crux in Seans report was particularly difficult. Roughly 40CM of snow at the trailhead. The cross ditch at 49.13290° N, 121.57390° W has definitely become deeper since I was last up here. Scraped the hitch really good on the way up and had to fill in part of the ditch on the way down to get across.

This is the crux, looking downhill. I took different lines in each direction, both worked.
This is around 850m, can't really tell here but the rock right in the middle is big & pointy.
Massive rock on road, lots of room to go around (thank you to whoever did the clipping). This pic also gives you an idea of the alder situation, I've driven many roads that were much worse
Ample time trailhead parking, noone checking daypasses here. I biked the first ~500m on Williamson Lake trail, saving 30seconds vs. walking
Not as bad as I expected, no major issues reaching Williamson Lake trailhead. I stopped to assess my line twice, once around ~850m where there was a large pointy rock in the middle of the road at a waterbar & again somewhere higher up (around 1,000m maybe?). No damage taken, didn't bottom out at any point. Still, this road is steep, rocky & narrow, no AWDs need apply, HC4x4 only. Alders were not that bad at all so don't know if someone has done some trimming? Ford Mountain FSR alders were 10x worse for reference.

49.13347° N, 121.56960° W Nice start to the road, and gets immediately steep.
49.13644° N, 121.57018° W Alder starts getting thick, some spots better, most spots worse beyond here. I hope you drive a lease lol.
49.13608° N, 121.57326° W Boulder on the road with some alder cut down to drive around it. Looks like the alder was just recently cut down.
49.13572° N, 121.57809° W Poor photo but a smaller cross ditch here, didn't scrape the hitch.
49.13887° N, 121.58696° W Parking lot with a view. Room for 4-5 vehicles providing everyone parks nicely.
Not a ton to add on top of Anton's nice report. The road is quite rough with TONS of alder. It is seriously bad, I really think this road will be lost in just a few years without maintenance. I tried to drive to the sides an run over some alder but it is so healthy it just springs back up. Seriously looking into a brush cutter and doing some work. On the road side of things I found it quite steep and rough leaving it in 4L and 1st gear at just putted the whole way up. Washout at ~800m which Francis describes could definitely stop people that need to drive their vehicle to work the next day. Past 2.5km I hope you painted your vehicle with a rattle can like I did because the alder gets real scratchy. Nice parking up top with room for 4-5 vehicles.

The road hasn't deteriorated since the last update in 2022, but it remains in very poor condition. A high-clearance 4x4 vehicle is essential to reach the Williamson Lake trailhead. We managed to make it to the end in a Tacoma without issues, though the pinstriping was severe. Had to exit the vehicle several times to assess the best route across water bars and large rocks in the road.
Francis Bailey reported on: Jul 09, 2022
One of the bigger cross ditches
I had to park before this section as it wasn't worth it to drive through. This is around 800m elevation
I found the road was in rough shape with a few very deep and narrow cross ditches that were impossible to avoid scraping on. Higher up I had to park after nearly getting high centered in my Tacoma at around 800m. Two vehicles did make it to the trail head though, so it's likely that more skilled drivers can make it the whole way.
