Grand Canyon of Tuolumne Loop

Hi there-

We have a permit at the end of the month to do a loop out of White Wolf down Pate Valley through grand canyon of the tuolumne, through Glen Aulin, and back via ten lakesf (so happy that Yos will now be open for our permit). We have done this loop once before and really loved it. Looking forward to seeing these areas again. This time instead of four nights we want to stretch it to five and decrease our mileage a bit... We are getting hung up on how to best break it up... from what I remember between Glen Aulin and ten lakes was the section that we would like to add a night. Does anyone know if there are places to camp between Poly and ten lakes along the water? We see a water source but not sure if it would be an adequate place to stay...

thanks much!
