The European Researchers’ Night stands as a beacon of scientific outreach and engagement. It unfolds as a platform for dialogue, enabling researchers to share their passion and latest breakthroughs with a diverse audience. In this talk, we delve into the journey of the Italian National Institute for Nuclear Physics (INFN) within this prestigious event. The INFN obtained so far a large number of financed projects and this contributed to the diffusion of the initiative throughout the national territory. With a focus on fostering the interaction between researchers and the public, our participation offers a kaleidoscope of engaging activities and enlightening discussions. Through interactive exhibits and hands-on experiments, the INFN showcases the intricacies of particle physics, inviting attendees to embark on a journey of scientific discovery. We describe our experience by including suggestions for improving the success of involvement in Reseachers' Night also in other countries.
