I actually visited this waterfall while doing a solo trip from Seattle to the Mowich Lake District of Mt Rainier National Park. A fair bit of the latter part of the drive is on a slightly washboardy unpaved road, but it was easily handled by the passenger rental car.

Once at the surprisingly busy car park at the end of the Mowich Lake Road, I then took a roughly four-mile round trip hike that started off with a descent from the campground into forest (make sure you veer left at a signposted junction within this forest), crossing a handful of creeks (most of them have single-lane log bridges over them or could be traversed easily enough by rock hopping) then proceeded to climb through several switchbacks.

Along the way, there was a signposted spur leading to the Eagle Cliff Viewpoint where I was able to get fine views (though somewhat against the sun in the morning) of the summit of Mt Rainier, some of the glaciers sliding down its slopes, as well as what I think was Giant Falls in the distance and some other unnamed cascades.

After a brief flattening out of the trail beyond the spur, the trail climbed a bit more before reaching another signposted spur for the Spray Falls Viewpoint on the right fork. Following this spur trail across another narrow log bridge then through a volcanic scree slope section, the trail then descended towards the rushing Spray Creek.

The official trail ended at the banks of the creek, but from here, I was only able to get a partial view of the falls as trees block the rest of its view. In order to get more satisfying views, I had to cross the creek as scrambling towards the middle of the creek with gore-tex boots only yielded marginally improved views.

So for most sane people, this would be the end of the Spray Falls hike. However, when Spray Creek has lower flow than what I experienced, it's conceivable that the creek crossing may not be as tense.

I did manage to find a way to get across the creek, but this was not easy by any stretch of the imagination. One mishap and you could find yourself swept downstream given the velocity of the water and the hard, sharp rocks jutting out from the rushing creek. If Julie accompanied me on this hike, she definitely would've talked me out of doing it.

Anyways, after much scouting around for feasible options to cross the creek, I stumbled upon a pair of large fallen tree trunks that I was able to use to scoot my way across more than 2/3rds the way across the creek. I wasn't sure if the trees were felled intentionally in this manner or if Nature miraculously put them there by dumb luck. Nonetheless, the remainder of the crossing required a short hop across a particularly fast moving part of the creek.

I went back across the creek the exact same way I came. Other options I considered seemed too dicey at the time given the high flow of Spray Creek.

As for the waterfall itself, it drops around 300ft or more in an unusually twisting manner giving it a bent funnel appearance. I think the combination of the sheer size of this falls along with its unusual shape was what made this falls both beautiful and memorable.

Since it's sourced by the melting snow at Spray Park (an alpine meadow further up the main trail with blooming wildflowers and views of Mt Rainier's north-northwest face), I'd imagine its flow diminishes as the Summer progresses. However, I was here in late August 2011 and the locals I've met during my hike said the conditions were more like mid-July conditions thanks to the unusually cool Summer and very hard Winter.

Finally, if you've got the time and energy, I highly recommend hiking the extra mile (as tiring as it may be with the many switchbacks) beyond the Spray Falls turnoff to Spray Park, especially if the weather is good. I was delighted to see several blooming wildflowers, the summit of Mt Rainier, and even a small tarn where the volcano was reflected!

Mundy Loss Rd (seemed like a residential road) hooks up with Hwy 162, when then headed east and hooked up with Hwy 165. Heading south on Hwy 165, the road passes through the small towns of Wilkeson and Carbonado.

Not long after a long single-lane bridge (roughly 3 miles past Carbonado), Hwy 165 splits where the right fork ascends steeply then becomes Mowich Lake Road, which is unpaved gravel road for the last 15 miles. The left fork leads to the Carbon River Entrance Station of Mt Rainier National Park (but the road was washed out just east of the ranger station so I wasn't able to visit Ranger Falls, which definitely would've been an entry in this website had I been able to visit it).
