Olallie State Park is a day-use park in the foothills
of the Cascade Mountains. It features dramatic waterfalls, cliff formations,
riverbanks and living old-growth trees up to 14 feet in diameter.
Six miles southeast of North Bend, on Interstate 90, in King County.
539.1 acres with 21,588 feet of freshwater shoreline on the south fork
of the Snoqualmie River.
The park was acquired in four parcels; the first in 1950 and the last
in 1991, for a total cost of $336,359.75.
In June 1976, the Highways Department made available to the Commission
a piece of property that united a number of Commission holdings in the
area. This became Olallie, which is the Chinook jargon word for berry.
The area abounds in huckleberries. Olallie includes Garcia Recreation
Area, Snoqualmie Pass Wagon Road Heritage Area and Twin Falls Natural
A hydro-electric power plant and weir is located at Weeks Falls, with
parking, viewpoints to the river and falls, and approximately 1/4 mile
interpretive trail and 2 vault toilets. Parking areas have been established
at both ends of the Twin Falls Trail. Each parking area has two vault
toilets. The park has a residence and storage building. A second hydro-electric
power plant is underground near Twin Falls.
Of Special Interest:
A one-mile hike leads visitors to two spectacular waterfalls,
including the 100-foot cascading Twin falls. Old-growth trees 12 to
14 feet in diameter add color to the park
6 mi. Hiking Trails
The rock-climbing area is adjacent to the park, above the Iron HorseTrail.
Rock-climbing equipment is necessary. Fatal accidents have occurred
when amateurs have climbed without proper equipment.
Olallie provides access to the Iron
Horse Trail, an old Milwaukee Railroad path that starts in North
Bend and extends to the Iowa Border. The Iron Horse Trail permits mountain
biking and horseback riding.
The river is open for fishing. Check local regulations.
