The ATLAS Collaboration offers a wide range of popular outreach programmes, enabling the public to explore the ATLAS detector at CERN in-person or through virtual visits. These initiatives make full use of the annual technical stops and long shutdowns of the Large Hadron Collider to provide guided tours to local audiences. At the same time, remote visitors can participate via video conferencing. Throughout the year, the ATLAS Visitor Centre remains the most visited experimental site at CERN, where guides introduce thousands of local visitors to high-energy physics research. The virtual visit system extends this engagement to a global audience, providing an interactive view of the ATLAS Control Room and the experiment. These programmes are popular not only for classrooms and groups around the world, reaching tens of thousands of visitors, but also for the guides, who have a chance to hone their skills at describing the detector, our research, and the value of international collaboration.
We present these programmes, recent developments, and current efforts to make them available to a broader and more diverse audience around the world.
