For more than 50 years, Cedar Falls was a thriving community on the Cedar River, generating public hydroelectricity for the city of Seattle.

While the town is now a memory, you can invite your family, friends, and neighbors to take a stroll under the evening lights of the historic townsite.

Twilight tours are 6 to 8:30 p.m. Saturday, Sept. 12 and 4 to 6:30 p.m. Sunday, Sept. 13.

Drop-in and stroll into the twilight to Cedar Falls, the birthplace of Seattle City Light. Walk back in time through the remaining restored houses and discover the setting and stories of those who worked, lived and grew up in this unique community of city workers and their families.

This year, the tour features guided interpretive walks and slide programs with Linda Carlson, author of “Company Towns of the Pacific Northwest,” as well as help from Seattle Public Utilities and Seattle City Light education staff and volunteers.

Visitors should wear good walking shoes and carry a flashlight. A shuttle bus from the Cedar River Watershed Education Center will be available.

No registration is required, and there is no cost. However, groups are asked to preregister.

Tours begin at the Cedar River Watershed Education Center, just east of North Bend at Rattlesnake Lake. For information call (206) 233-1515, e-mail to crwprograms@seattle.gov or visit www.Seattle.gov/util/crwec.
