Which means that everyone has to go up the Mist Trail to the top of Vernal, until the JMT opens up again. The Clark Point cutoff is a really nice variation: a little cooler than the upper half of the Mist to Nevada (as its on a north slope) and great views of both falls and the Valley.
Top of either Vernal or Nevada are great places to hang out. Probably more to see at Vernal, with the Emerald Pool, but once at the top of Nevada, it is an easy, almost flat stroll all the way to LYV campground, along the river, a lot of really nice spots to hang.
Tough to get lost in any of these spots: its like central park most nice days; there's even a bathroom at the top of Nevada. All the kids & city folk on the trail might even be an inspiration to go farther
