Overview: This popular trail follows the South Fork of the Snoqualmie River through the rainforests along the western edge of the Cascade Mountains. The trail provides spectacular views of Twin Falls. Most people park at the Twin Falls Trailhead located off of Exit 34 on I-90. A little over a mile from the trailhead, a set of stairs descends to a viewpoint of the Lower Falls as they plunge over a 150 foot cliff. Hike another quarter mile to a bridge that spans the narrow Twin Falls canyon. From the bridge you can see several plunge pools of the Upper Falls upstream and the edge of the Lower Falls downstream. Less than a quarter mile from the bridge is a view of the Upper Falls from above. Most visitors turn around at this point as the trail starts climbing steeply. Those hearty enough to continue will find that, the trail intersects with the John Wayne Pioneer Trail in a little under a mile. The John Wayne Pioneer Trail is a 108 mile long trail that follows the old Chicago-Milwaukee-St. Paul-Pacific Railroad from Cedar Falls to Vantage. Hike east along the Pioneer Trail for a quarter mile to reach the Olallie State Park Homestead Valley Trailhead (located off I-90 Exit 38).

Tips: Discover Pass is required.

Dogs on leash.

Avoid the summer crowds by visiting on a weekday.

Parking at the trailhead is limited.

Points of Interest


Twin Falls Trailhead

While this hike can be started from either trailhead, most find that the 2.5 mile out and back hike from the Twin Falls Trailhead to the Upper Falls Viewpoint is the easier and more scenic route.

Getting to the Trailhead:
Take I-90 Exit 34 just east of North Bend. Drive south on 468th Ave SE for approximately one mile (follow the brown Olallie State Park signs). Turn left on SE 159th St and follow it approximately one mile. This road ends at the Twin Falls Trailhead.

South Fork of the Snoqualmie River

For the first half mile, the trail follows the path of the South Fork of the Snoqualmie River. Several small swimming holes can be found in this area and are popular for cooling off on a hot summer day.

First Glimpse of Twin Falls

After leaving the river, the trail climbs 500 feet over the next quarter mile. At the 0.75 mile mark, the trail crests a ridge where you will get your first glimpse of Twin Falls. A couple of benches make this a nice resting spot.

This makes a good turn around point for those with small children since only half of the climbing to the bridge is complete.

Old Growth Douglas Fir

After descending from the bench viewpoint, the trail passes an old growth Douglas Fir tree that is protected by a fence. This old giant is over 32 feet around the base of its trunk (10 feet in diameter) and is estimated to be between 400 to 700 years old.

Lower Falls Viewpoint

After climbing another 400 feet, just over the 1 mile mark, you will see a set of stairs descend down the side of the canyon. Follow these stairs to the best view of the falls in the entire park, the Lower Falls Viewpoint.

Twin Falls Bridge

Less than a quarter mile past the stairs to the Lower Falls Viewpoint, you will reach the Twin Falls Bridge. The bridge traverses a narrow canyon and passes between the upper and lower cascades of Twin Falls.

While this is the most popular turn around point for most hikers, the short hike up to the Upper Falls Viewpoint is worth the effort.

Upper Falls Viewpoint

A short, but steep climb past the bridge will bring you to the Upper Falls Viewpoint.

This is the last scenic view for eastbound hikers, so few continue on from here.

Junction with John Wayne Pioneer Trail

The first quarter mile past the Upper Falls Viewpoint is the steepest part of the entire trail. The steepness eases, but continues to climb for the next half mile. At the 2 mile mark, the Twin Falls Trail intersects with the John Wayne Pioneer Trail.

The John Wayne Pioneer Trail is a rails to trails conversion of the Chicago, Milwaukee, St. Paul and Pacific Railroad that runs 108 miles from Cedar Falls (North Bend) to Thorpe.

Junction with Homestead Valley Access Trail

Head east on the John Wayne Pioneer Trail for a half mile until you see another trail junction on the left. This quarter mile access trail takes you to the Homestead Valley Trailhead.

Homestead Valley Trailhead

The Homestead Valley Trailhead is accessed by I-90 Exit 38.

Easy, consistently great no matter the season (mud is expected in the rain!!). This is my standard go-to hike for visitors or just when I want a quick, easy hike with my dog.

Went there when our puppy was about 4 months and just wanted to head out so that our terrier could get use to hikes gradually. We didn't visit both falls, but small portion that we did was quite nice.

The trail follows the river so you get water views throughout the hike. It's pretty easy with a mild incline so it's great for beginners with a good payout in terms experience over effort.

Perfect for families and kids, especially for first timers. Beautiful scenery along the trail, which follows the river for much of it. Plenty of places to rest and sit along the rocks of the river for picnics and playing in the waters of the river. There are some steep slopes, but easier compared to Rattlesnake. Waterfall is not nearly as impressive as Snoqualmie Falls, but still worth the hike!

NOT - I repeat - NOT "easy." Should be rated "moderate." It is definately beautiful and the first 1/2 mile is easy but then it starts up and goes up and down and up again to the bridge across the falls. The view was worth the hike but people should know what they are getting into. We are healthy and in good shape and it was not a problem but it really is not "easy." The grade is very steep and since you go up and down and up and down you do get a break but the ups are steep enough that they should be rated moderate. In order for a hike to be rated "easy" it should be easy the entire way. So if you are in good shape and have good knees - enjoy!!!! It is a BEAUTIFUL hike.

I am not a regular with hiking. But I liked the trail. I started my trek by 10:30am and was back in less than 2 hours, without much of a hurry. While the upper fall is the last point on this trail, I actually liked the view of the lower falls. Most of the trail is through deep forestation and hence one can only get limited scenic views (or opportunities to take great photos). But at one can easily approach the water front and enjoy the flowing waters. I did not get into the water (water was very cold), but the more adventures ones can do that. Overall it was a relatively easy trek.

Directions: I took I-90 East from Bellevue and took Exit 34. Make right on to 468th Ave SE and go for about a mile. You would see the brown Olallie State Part and Twin Falls Trailhead signs. Make left on SE 159th St and that road ends at the Twin Falls Trailhead. Discover pass is required (and I bought one at Big 5 Sports store), and a single day pass is also available at the pay station right in the paring lot at the Trailhead.

I have limited experience with hiking, but I have to say that I was overcome by the beauty and lushness of this place. It was a typically rainy PNW day in the mountains, so the trail was a bit slippery in places, but easy to follow. The sounds were primarily of rushing water and birds calling, with traffic noise audible from a nearby road at only one point. I went out fairly late, so I didn't go past the Twin Falls Bridge, but I thoroughly enjoyed stopping there and at the lower viewpoint (and being covered in the mist rising up from the waterfall!), as well as a few little stops along the water on the way up. No complaints - I had no problems with parking or finding my way there, despite it being a Saturday (albeit late in the day).

I guess I'm biased since I work here, but this is the best waterfall hike in the Seattle area!
