Frommer's Review
Although rather difficult, this trek is satisfying, as it takes you from a stunning waterfall through meadows and forests to some lovely lakes. The first day's hike is 8 miles, to Chilnualna Falls, one of the park's tallest falls outside the valley. It's a strenuous climb up. The bottom fall tumbles down a narrow chute, and 50 feet up is yet another fall; the combination can be quite a vision in spring with a strong winter runoff. Above the falls, the trail ascends via switchbacks up a gorge to a junction. One route will lead through forests toward Bridalveil Campground, the other toward Chilnualna Lakes. Take the Chilnualna Lakes route. Just below this junction are several nice places to camp overnight. There are also a number of nearby swimming holes. From here, it's a climb along the headwaters of the creek to a set of high-altitude lakes. About 2.5 miles up is Grouse Lake Creek. This can be a tough cross during high water, and the rock is very slick, so be careful. Head north (left) for about 0.5 miles after the crossing toward Turner Meadows. At the next junction, head right (east) toward Chilnualna Lakes, about 5 miles away. Buena Vista Peak rises above the lakes. Campsites are plentiful in this area. From the lakes, head up into 9,040-foot Buena Vista Pass. At the pass, head south on Buena Vista Trail toward Royal Arch Lake. The next junction goes right (west) toward Johnson, Crescent, and Grouse lakes. After Grouse Lake is the Grouse Lake Creek crossing and the return trail to Chilnualna Falls and the parking area.
