Public Tours

Discovery, accelerated

Canada’s particle accelerator centre is openly accessible to the public for walking tours year round. We are home to the world's largest cyclotron particle accelerator and a system of high-energy rare isotope beams that enable a diversity of efforts in nuclear and particle physics, accelerator science, life science research, and more! 

Tour participants get first-hand experience with many of TRIUMF's experiments and facilities as we follow the path of the proton from its origin bound in a hydrogen atom to its destination in targets and detectors. 

As of January, 2023, TRIUMF's public tours program remains on hold as the lab continues to explore options to reopen later this year.

Please refer to @TRIUMFLab on social media for updates to this program as they are provided. 

TRIUMF has developed and announced a brand new website titled, Discover Our Lab, for continued exploration and awareness of the lab, its purpose, and its impact on science in Canada and around the world.  

For business releated visits refer to the staff-led tours policy under Quick links. 

General details regarding public tours at TRIUMF follow.
