Tueeulala Falls is located on the north side of Hetch Hetchy Valley in Yosemite National Park.
At roughly 880 feet it is the smaller of two large waterfalls that spill into Hetch Hetchy Reservoir, the other being Wapama Falls.
It is, however, the larger of the two in terms of greatest free-fall distance, as Wapama is split into two falls.
The hike to the top of the falls is off trail but fairly brush free and straightforward.
This is due to it being located on a seasonal distributary of Falls Creek, the primary channel of which flows over Wapama Falls, that only flows during spring snowmelt when water from the creek rises sufficiently high.
