Open Houses
Summer 2025 Schedule
Our FREE Open Houses are held on most Friday evenings when CU classes are in session. We hope to see you there!
Open houses are only held when the skies are clear. If you're not sure if we'll be open, check out our local weather, check our twitter, facebook, or instagram at 8pm, or call us, on Friday night after 8:45pm, for an observing status at 303-492-2020.
There is no charge for the Observatory's Open House nights ... the stars are free to everyone! Sessions typically last from 1-3 hours, depending upon the weather and the quality of the night.
- Our summer open house schedule will be posted soon. We expect to start up again in late May or early June.
Please note, looking through the eyepiece of the telescopes often requires climbing a step ladder. However, we also have cameras that can take pictures of what the telescope is seeing and they will be displayed on large screens on the observing deck.
The University of Colorado Boulder is committed to providing equal access to individuals with disabilities. If you are planning to attend and require accommodations, please contact our Observatory Manager no later than 7 days before the event. We will make all reasonable efforts to fulfill requests submitted after the deadline.
