I was able to make it to Branch 2 with my Honda Odyssey minivan. As stated in the FB group, one of the bridges is heavily decayed. I think the main worry is hitting a large spike/nail with your tire. We were able to navigate over it and the joists and big logs underneath were still in good condition. I bottomed out a once or twice on the way to branch 2. We went a tad ways up it and parked at a pullout but if I were to do this again I would just park at the turnoff. Decent amount of pin striping

Narrow, couple spots where a bit of clearance helps but no major washouts or waterbars. Some very small thin alders will brush against your vehicle, but wouldn't consider it too "pinstripy". Parked at Holly Lake TH, hiking trail from there was in great shape to the lake.
