Observatories in Vermont: The Complete List

Vermont’s dark rural skies and rolling hills make it an appealing place for anyone who likes looking up. Small towns, easy access to high vantage points, and community-run star parties mean you can often pair a scenic drive with a night of telescope viewing.

There are 5 Observatories in Vermont, ranging from Green Mountain Observatory to Stellafane Observatory. For each entry you’ll find below the columns City, Type, Main telescope aperture (in/cm), so you can quickly compare locations, public access, and the size of the main instrument you’ll see — you’ll find below.

Are any of these observatories open to the public?

Many Vermont observatories offer public nights, seasonal programs, or special events; check each site’s calendar and contact information in the list below, since some require reservations or are limited to members and scheduled outreach.

How should I plan a visit if I want to see more than one observatory?

Map the observatories by city, pick evenings with clear forecasts, and prioritize sites by the telescope aperture or program type you prefer; allow travel time between rural locations and confirm public access before you go.
