Twin Falls (Olallie State Park)


Naturalist Trip - Twin Falls (Olallie State Park)

Join us for a short hike to explore nature! The Twin Falls trail is about 3 miles with 500 feet elevation gain. While wildflowers will be gone there is so much more to look at. This hike also has some fabulous views of the South Fork Snoqualmie River including three waterfalls and hopefully fall color. We will take our time and move slowly – possibly 3 hours.

  • Easy
  • Moderate
  • Mileage: 3.0 mi
  • Elevation Gain: 500 ft
  • High Point Elevation: 1,000 ft
  • Pace: we will take our time and stop frequently

Meet at the Lower Twin Falls trailhead at 8:15 am so we can start at 8:30 am.

Take Exit 34 off of I-90, turn right onto 468th Ave SE, and drive ~0.5 mile to SE 159th St. Turn left and continue another 0.5 mile to the Lower Twin Falls Trailhead parking lot at the road's end (620 ft). DISCOVERY PASS REQUIRED but a kiosk is available to purchase a day pass.  Bathrooms are available at the trail head.

This is a popular “close in” hike so the parking lot fills early.  Carpooling is recommended. 

You can also get directions to the main trailhead (Lower Twin Falls) and even weather prediction here:

It might seem like a letdown when all the spring/summer flowers have faded but, on this hike, we will focus on learning how to look/experience the rest of our lowland forest.  There are over 60 native species of plants and trees on this trail including five types of ferns.  And that doesn’t include mosses and/or lichens we may come across.   Sometimes the point is not to learn how to identify all 60 species but how to notice and appreciate all the variations in color, patterns, habitat and perhaps learn a few.  The Western Wildflower Search app and the Seek app will come in handy as we explore. 

I am certainly not an expert but I am an enthusiastic nature-seeking volunteer.

Bring your lunch and we can eat by the river after our adventure exploring this pretty area.

An email will be sent out a few days before the trip with further instructions or updates.
