Stewart Falls is a very scenic two-tiered waterfall located on the east side of Mt Timpanogos: 40.386242°, -111.604515°. The trailhead is at Aspen Grove: 40.404067°, -111.605068°, along the Alpine Loop.
It is a fairly easy hike along a well-maintained trail, with signs marking critical junctions. Hiking time one-way is about 1 hour for most people. (Guests at Sundance Resort can hike to the fall via a shorter trail.) A fee is charged for day-use along the paved Alpine Scenic Loop Road.
There are two other smaller waterfalls in this area that can be seen from maintained hiking trails.
