Weeks Falls
   King County, Washington

[ Physical Makeup ]  [ Pictures ]  [ Maps ]  [ Update History ]

Weeks Falls is the fourth of five major waterfalls along the South Fork Snoqualmie River. The river cascades down a jagged pitch, dropping 77 feet in a run of about 300 feet. Immediately above the falls is a small dam which diverts about ¾ of the river into a micro hydro facility, leaving the falls a shadow of their natural self for the majority of the year. A visit between January and May should yield better results. The photos shown here were taken in late May of 2006 when the river was running at about 900 cubic feet per second. Weeks Falls is enclosed in a lightly developed corner of Ollalie State Park, with trails connecting to Iron Horse State Park and the Twin Falls section of Ollalie as well.

HISTORY AND NAMING INFORMATION

  • Weeks Falls is the Official name of this waterfall.

LOCATION AND DIRECTIONS

To get to the falls, drive east on I-90 to exit 38, and turn right after you've exited the freeway. Follow the road to the entrance to Olallie State Park (which isn't signed very well, so look for a small pair of parallel bridges over a small creek, and take the left fork). Drive down this gravel route for about .7 miles to a turn-around. Park where you can and walk towards the falls which you should be able to see from the parking area.
