Leigh Lake is located in Grand Teton National Park, in the U. S. state of Wyoming. The glacially formed lake is 2.4 miles (3.9 km) wide and 2.8 miles (4.5 km) long from north to south. Situated just southeast of Mount Moran, the lake is at the terminus of both Paintbrush and Leigh Canyons. The lake can be accessed from the Leigh Lake Trail which follows the eastern shores of String Lake a distance of one mile (1.6 km) and is an easy hike over level terrain.
