Mount Si High School, Twin Peaks High School

The front of Mount Si High School in Snoqualmie as it looked in 2011. The pilot used this school for Twin Peaks High, filming its hallway, classroom, courtyard and library scenes here as well as the outside. This is one stop you can no longer see as it was: the old campus was demolished in 2019, and a new school opened on the site that September. It is also a working school, so look from the street.
