I've done this loop as part of two different hikes.
Grand CanyonIt's been a while since I was here, so I don't remember much. We did find a rattlesnake in our camp. Not far below Register Creek there is a large, deep pool in the river, below a natural waterslide. We took great advantage of this setup and found it very refreshing. The water will be higher for you, so use your own judgment.
Glen AulinYou may be aware that the bridge over Conness Creek to enter the camp is
damaged. Not sure what's going on with the camp itself. Personally, I would stay away from it in any case, unless you want to go swimming.
Tuolumne PeakI'm not sure if Dave and I are talking about the same thing, but here's my experience with Tuolumne Peak. I've camped twice at the two lakelets just west of the pass over Tuolumne Peak's northeast spur. From the upper lakelet, or even from the pass itself, you can get right up onto the spur. I went part of the way and found it to be a pleasant ramble, but ran out of time and went back to camp.
The pass has a bunch of false summits, but when you actually get to the top of it, you will clearly see one lakelet. The other is just out of sight beyond it. Plenty of beautiful campsites there, including some that are legally away from the water. That whole north face is gorgeous.
Ten LakesWell-populated, especially the two lakes nearest White Wolf. When I came this way, I found solitude at the northernmost Ten Lake, a fairly easy jaunt from the trail (not the northeastern lake -- I don't have a death wish). Just north of this lake is a little ledge where you can catch a glimpse of the river, 4000 feet below. I recommend this!
