…as a BAD side trip from the JMT, it seems. Everything you mentioned sounds great, and the cloud rest jct. camping is good, with water and a pretty area. Last summer, it had a lot of nosy bears though, so bear canister or kiss your food goodbye.
The 2 sidetrips you didn’t mention that i really liked were Split Mtn. and Mt. Muir. Split is right after Mather Pass. You can camp at the Lake and then go around its south shore, head to the saddle north of Split, and follow the ridgeline up. It was pretty easy…no trail but no hands climbing. Mt. Muir, on the way down from Whitney, is very short, but a little more technical. If you’re doing Ritter, Muir shouldn’t be a problem for you. Refer to summitpost.org, their page on it, for route info, pictures, etc.
I would like to do Cathedral Peak, but we didn’t have the time. Rainbow Falls from Reds Meadow is a nice walk between meal #1 and meal #2 (2 hours later). I’d like to take the Fish Creek trail from Reds to Ida Bell hotsprings, but i just read a report from someone who said they couldn’t find the hot spring. Speaking of hot springs, Blayney springs near Muir Trail Ranch was really nice, and this year the river crossing to get to it should be easy. I wouldn’t miss that side trip either. VVR is a sidetrip maybe worth missing.
How about Middle Palisade? Anyone done that from the JMT? Or Mts. Tyndall and Williamson? Those look doable if you have 2 extra days.
