About Pywiack Cascade
Pywiack Cascade (sometimes known as Slide Falls) is an interesting sliding waterfall at the head of the rugged Tenaya Canyon. It’s said to slide from a cumulative height of 600ft though it seemed to be difficult to get a full view that would have made us confirm or deny that plausibility of that claim. Moreover, it’s another one of those Yosemite Waterfalls that manages to elude most of the park’s visitors since it’s rather hidden in addition to difficult to view satisfactorily. This characteristic seems to be typical of waterfalls in Tenaya Canyon (another example is the elusiveness of Snow Creek Falls) and I suspect a big reason why would be the inaccessibility of Tenaya Canyon itself.
To illustrate how elusive Pywiack Cascade was, we either had to be very observant from the lookouts near Glacier Point, or we had to go an a bit of a little-known minimum of six-mile round-trip out-and-back back overlooking parts of Tenaya Canyon. I’m sure there must be ways to gain better views than we were able to attain given a photo we saw in the Osborne book on Yosemite Waterfalls
Even though this waterfall is on Tenaya Creek so it’s sourced by Tenaya Lake, I believe Tenaya Creek still only has seasonal flow. This claim is supported by the fact that Mirror Lake tends to dry up once the snowmelt period is over in the mid- to late Summer. Thus, a visit to this waterfall would require timing to be in the late Spring.
To my knowledge, there is no official trail to get to the base of this waterfall for Tenaya Canyon is too rugged and said to require technical gear to navigate through the terrain. However, the following is how we managed to experience this cascade.
Pywiack Cascade Viewpoint
Hike to Pywiack Cascade Viewpoint
From here the trail started to present views of Tenaya Canyon, an unnamed ephemeral cascade, and ultimately a partial view of Pywiack Cascade. Unfortunately, the official trail only afforded us views of about a half to two-thirds of the waterfall as a granite hill (possibly Mt Watkins) sat in the way between our vantage point and the cascade itself.
In order to overcome this visual obstacle, we continued further west to a short scramble for better views between trees. I’m sure it might have been possible to climb up the nearby Mt Watkins for an unobstructed view straight down at the impressive cascade (but we didn’t actually do that so we’re not sure if this truly the case or not).
This was the turnaround point for us. However, we could have extended the hike by continuing further to the Snow Creek Trail. If we didn’t arrange for a shuttle to make it a one-way point-to-point hike, then that might push the limits of what we’d be willing to do as an out-and-back hike in a day. The Snow Creek Trail ultimately would descend into Tenaya Canyon and join up with the Mirror Lake Loop for a total loss of 4000ft in elevation, and I believe it’s 11 miles one-way from Olmstead Point into Tenaya Canyon.
Distant Viewpoints
Distant Viewpoints
Perhaps the most obvious lookout spot would be at Glacier Point (signpost G11), where we were able to look deep into Tenaya Canyon beyond Half Dome and spot this cascade in the distance. In order to photograph the waterfall, we needed a telephoto lens to bring it up closer to our field of view.
Alternately, we were also spotted a similar view of Pywiack Cascade on the summit of Sentinel Dome (trailhead at signpost G8). Since this viewpoint was a bit further than Glacier Point, it wasn’t the most obvious place to spot it. Plus, an even more powerful telephoto lens would be required to photograph it without the waterfall being a small dot in the picture.
Finally, we were able to get perhaps the closest views of Pywiack Cascade from the south side of Tenaya Canyon by doing the Half Dome hike. Unfortunately, getting to where we started to see the waterfall was about 6 or 7 miles into the gruelling hike (just before we started to make the last stretch of climbing onto the Half Dome saddle). But since the Half Dome hike was much more gruelling than the hike we’ve suggested earlier to see the cascade, it might not be worth your while if the cascade was the sole purpose for doing the longer hike. For details on the Half Dome hike, see the Snow Creek Falls page.
We’ll describe the directions to our favored starting point at Olmstead Point from Mammoth Lakes. This is a Summer only route since the Tioga Road needs to be snow-free and free from avalanche danger to be open to the public.
Basically, we go east on Route 203 to the Hwy 395, then take Hwy 395 north for about 30 minutes or so in the direction of Lee Vining. Before reaching town, we turned left onto Route 120 (Tioga Road) and climbed up the steep and rugged road to Tioga Pass. About another half-hour’s drive or so would lead us beyond Tenaya Lake and towards Olmstead Point, which has a well-established pullout area.
Driving to Mammoth Lakes from Los Angeles typically takes roughly 5 hours without traffic (via the Hwy 14 and Hwy 395).

Pywiack Cascade hiking accident fatal to Tahoe doctor October 16, 2008 12:38 am - There were two missing hikers in Yosemite one morning in 1970 and the rangers requested several of the more or less permanent rock climbers in Camp 4 to participate in search parties. My party was sent down a very steep, very brushy gully from the vicinity of the Tioga Road to the base of Pywiack… ...Read MoreVisitor Reviews of this Waterfall:
Elusive Pywiack May 25, 2013 6:11 pm - Yep, Pywiack is an elusive falls, tucked in fold in a canyon and viewable from narrow angles. I once did a one day trek from Tenaya Lake to Yosemite Valley. We chose to go when the water was low. The swimming hole at the bottom of Pywiack was just splendid. This hike is not for… ...Read More
