I took our 7 year old to Chilnualna Falls for 2 nights from 6/6- 6/8. The trail is dry to the top of the falls, and we saw no snow even in deep shade. There was very little mosquito activity, even in the morning and evening. For a midweek trip before all the schools are out, we expected and saw few other people. There were 2-3 groups camping in the area and maybe 8-10 day-hikers. There are aby squirble - Backpacking and Hiking Yosemite and the Sierra
