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. 

[Updated March 13, 2020]: Due to the rapidly evolving novel coronavirus (COVID-19) situation, the public tours program has temporarily been placed on hold. Please refer to TRIUMF's COVID-19 resources page for further updates.

For the beginning of 2020, TRIUMF will offer Wednesday tours at 1:00PM. These tours are led by volunteer staff, and are limited to the first 15 reservations booked. See links below to register once, for every visitor in your group.
