Teen Takeover Saturday

The library hosts an after dark party for teens on the second Saturday of the month.
  • NOTE! Our fall Teen Takeover Saturday will be held on October 14 instead of September 9.
  • This is a drop-off program for Tweens and Teens, 6th through 12th graders.
  • Watch this space for programming details to come.
  • If you prefer something quieter, we will have our computer lab up and will screen a movie. As always, pizza and soda will be served.
  • Registration is required and is limited to first 100 registered participants. Participants must register before noon the day before the program to allow time to have adequate staffing. Participants will be required to sign in when they arrive and provide an emergency contact number. Register here.

The Friends of the Longmont Library generously support library programs and services.
