Tueeulala Falls is a tall seasonal waterfall, roughly 880 feet in total drop, that spills into Hetch Hetchy Reservoir in Yosemite National Park near its larger neighbor Wapama Falls. It is reached on the trail from the O'Shaughnessy Dam and often dries up by mid-summer.
It ranks #10 of 775 by documented height in this guide.
The falls are fed by Tueeulala Creek. It lies in Tuolumne, California. The site is on public land managed by National Park Service.
This is a moderate hike waterfall: a longer day hike, roughly one to several miles each way. Reaching it takes a moderate walk, so budget time and pack water before you set out. The walk to the main viewpoint runs about 5 miles round trip. The nearest town is Mather.
When to go: spring (often dry by mid-summer). Flow usually peaks after snowmelt and heavy rain and tapers through late summer — a quick look at recent streamflow and the managing agency's conditions page can save a wasted trip.
