Mount Stromlo Observatory


Mount Stromlo Observatory is the headquarters of the ANU Research School of Astronomy and Astrophysics, a world-respected community of researchers exploring the heavens.

Members of the public and school groups are welcome to come and explore the Visitors Centre and Heritage trail, and join in with activities such as stargazing or talks - check out the calendar.

You are also invited for a relaxing coffee or lunch taking in the wonderful views from the café.


The Visitor's Centre has something for everyone with science exhibits, a kids zone and info about Mount Stromlo’s rich history of tragedies and triumphs.

There’s also a heritage trail with augmented reality to transport you to a different time as you stroll past kangaroos taking in the sweeping views across Canberra and the surrounding mountains.

Visitors Centre
