The Best Sight in Grand Teton National Park, Wyoming

Take Jenny Lake Boating's 20-minute boat ride or the 2¼-mile (each way) Jenny Loop Trail around the south side of the lake from the Jenny Lake Visitor Center to the start of a gentle, ½-mile climb to 200-foot Hidden Falls, the park's most popular (though crowded) hiking destination. Listen for the distinctive bleating of the rabbitlike pikas among the glacial boulders and pines. The trail continues half a mile to Inspiration Point over a moderately steep, rocky path with sweeping lake views. From here, continue west another 1½ miles into the heart of Cascade Canyon, with its dramatic views through the mountains and out toward Petersen Glacier. With the 10-minute boat shuttle ($20 round-trip or $12 one-way), plan on a couple of hours to experience this trail—add another two hours if you hike the whole way, which is your only option from October through mid-May, when the shuttle doesn't run. Easy–Moderate.
