Here is my own report. Rode bike from Foresta to El Portal and back on Foresta Rd. Foresta falls are great and bridge is fine.
Second bridge at second falls is marginal. Just a few board across. Not horrible but would not be good to fall.There is line across with a rope with carbiner on it. Not sure how helpful is was.
Third bridge is fine.
Several locations are washed out so you need to carry bike for short sections.
Lots of wildflowers still.
I did it on crossbike but marginal. Would have been better on full mountain bike especially in sections where road was pretty beat up by runoff.
Overall a fun adventure.
