We are planning on taking a group of students from Lyell Canyon, over Vogelsang, and down through Little Yo to the Valley. We have our permits, but as a backup I got permits for the Grand Canyon of the Tuolumne from White Wolf. We did the GCT a few years back in late June and I have assumed that it's usually a doable route in June. However, I'm now thinking I should check. Is the Grand Canyon of the Tuolumne a good bet to be open the 3rd week in June?
Thanks for your help!
