Was able to make it past the washout in a stock 23 Tundra. Undercarriage and bumpers touched down especially back bumper on return trip. Seems pinstripey but paint job looks fine afterwards.
Went for a drive after work to test a friend's new rig. Have heard it's worse than it used to be, but it wasn't that bad. A good crossover can still get to the trailhead. The big washout is deep but wide, so bumpers won't get crunched too easily. Beyond that, there are some ruts and holes, but open diffs are fine with any modern traction control system. Overgrowth is not pinstripy yet, just a little annoying at worst. If you can get to this branch, you're probably good to get all the way tbh. The branch 200 section has actually degraded over the last couple years, more so than this
Thought i'd say it isn't impossible... Made it to the end of the spur for a Tricouni hike, pretty doable in something like a suzuki sidekick. Made it up in a stock clearance tacoma but barely squeezed across a semi-washed out bridge around 2km, there’s plenty of parking space right before that bridge for rigs that made it through the washout but too wide to squeeze past. A few other manageable drainage ditches along the way and it gets pretty rocky and bushed-in during the final stretch up to the parking. If you plan to go past the first washout, I hope you aren’t worried about pinstripes! (At least in the summer)
Katrina Kuba posted on Facebook in the Squamish Ski Mountaineering & Mountain Running Club, that this branch has a washout right at the start of it. This is the road to Tricouni
