We did a loop from Union to Rock Lake, trail lost through tree fall to end up up at Duck lake and back to Union. We got ~12 miles.
I see Stanislaus Mdw to Bull Run and Heiser to Mosquito and back to Stanislaus Mdw for 8-10 miles.
With a car shuttle we could get the whole of ART.
What other ~8-12 mile hikes are there that are NOT out-n-back? Prefer loop trails but shuttling could work sometimes.
I don’t see anything promising from Sourgrass nor Sand Flat/Wolfboro, wouldn’t it be nice if the two were connected by a river-side trail the whole way!
