Illilouette Fall is a 370 feet (110 m) waterfall in Yosemite National Park. It is located on the Illilouette Creek, a left tributary of the Merced River, in a small side canyon directly across from Vernal Falls, and is visible from the trail to Vernal and Nevada Falls. The best vantage point is from the Panorama Trail as it descends from Glacier Point.
