The hike surrounding Sahalie and Koosah Falls is one of those places that's always stunning, no matter the season.
In the driest and hottest months, the waterfalls are still booming, the old-growth forest provides shade and there's even a few frozen pools to cool off in — for those brave enough.
In spring it's a lush riot of green, and even in winter, when covered in snow, it makes one of the state's most scenic snowshoe adventures.
Thanks to one of the world's largest subterranean aquifers, this hike past the McKenzie River's two most impressive waterfalls is always a winner 90 minutes from Salem and Eugene. It's accessible to everyone from children to older adults.
The full loop is 2.6 miles and passes the 70-foot waterfalls twice each while visiting countless smaller falls and azure pools along the way. There are fun historical facts to know as well — like famous cats and kayakers being launched over the waterfalls.
Post-hike, there's an ideal spot just across the highway for food, dessert or more recreation at the McKenzie's headwaters.
Sahalie-Koosah isn't a hidden gem, but it is one of Oregon's best short hikes and worth considering for a day-trip adventure almost any time of the season.
There are three places you can park and start this iconic loop just off Oregon Highway 126. The easiest is the Sahalie Falls viewpoint, although it's often crowded with people just stopping to check out the main attraction.
The next option is to continue south down 126 to the turn off for Ice Cap Campground and Koosah Falls, which has its own parking lot. And finally, Carmen Reservoir Road has its own trailhead, at the spot where the loop connects on the south side.
There are plenty of fun facts and oddities about Sahalie Falls, which means "heaven" in Chinook jargon, and Koosah, which means "sky."
First, nobody can agree on its official height. It is listed on the internet at countless different heights from 70 to 100 feet.
I didn't measure it personally, but the best source is typically Northwest Waterfall Survey. It says 73 feet, so we'll go with that.
It's also quite well known for people launching themselves off it.
In 1998, whitewater kayaker Shannon Carroll set what was then the world record for the highest decent — helping usher in the era of kayakers launching themselves off waterfalls. Two decades later, in 2021, kayaker Dane Jackson raised the bar by doing a "back freewheel" off Sahalie — he went off backwards and rotated forward.
My favorite send of this waterfall, however, wasn't a person — it was Sassy the Cat, who was launched off the falls at a pivotal point in the classic movie "Homeward Bound." It was just one of the many scenes filmed in Oregon for the movie.
It wasn't a real cat, since filmmakers actually went to pains to make sure no animals were harmed in making the film.
There's so many parking spots that there's no "right" way to hike the loop. I've gone both directions and don't think there's a big difference.
In late August, I took a troop of kids and started from the Sahalie viewpoint, then followed gravity downhill toward Koosah.
While the views of the main waterfalls are great, for us, it was actually the numerous smaller waterfalls, rushing into clear turquoise pools, that brought the most scenic moments. There are even a few pools you can dip into, as long as you're willing to risk the ice cube temperatures.
The hike follows trails on both sides of the river — the far side is the 26-mile McKenzie River Trail. The loop is connected by a wooden bridge (on the north end) and Carmen Reservoir Road (on the south).
The bridge is fun and scenic, but the road crossing near Carmen Reservoir was better than expected. There's a nice picnic table for lunch, and drivers of the Eugene Water & Electric Board trucks that rumble past are happy to pull their horn upon request, as the kids discovered.
Other than that, it's just a nice hike among giant Douglas firs and western redcedars, the ice-blue river and past the waterfalls.
Visit Silver Falls State Park in late summer and fall, and you might be a bit disappointed. The waterfalls dry up to a thin cascade after months without rain.
The same is not true for Sahalie, Koosah and the McKenzie River, which are fed by a massive subterranean aquifer below the Cascade Mountains. The High Cascade Aquifer holds around 81 cubic kilometers of water— or three times the volume of Lake Mead, the United States' largest reservoir — between Mount Jefferson and McKenzie Pass.
Hydrologists say that all the rain and snow that falls on the Central Cascade Mountains is absorbed into volcanic rocks and works its way underground for years before emerging at springs that fuel streams like the McKenzie. So no matter how dry it gets, the McKenzie is still rushing with cold, clear water.
The hike is short enough that it only takes an hour or two, which does leave time for a post-hike hangout at the headwaters of the McKenzie River.
Clear Lake Resort is just up the road from Sahalie Falls, and features a place to order food, dessert or ice cream. If your crew has any energy left, you can take a rowboat out onto the water or go fishing.
It's a nice way to end a day that showcases one of Oregon's best short hikes — worth visiting any time of the year.
