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. 


Public tours, online booking

Tours last 60 minutes, with time for Q+A and photography throughout.  

  • Open to the public Wednesday at 1PM Pacific Time

Group tours, online booking

TRIUMF welcomes tour groups from a diversity of backgrounds and interests; group tours follow the same route as public tours, but can accommodate special requests for more information or special attention to certain TRIUMF experiments, facilities, or other competencies. 

Tours for groups larger than 6 people are free of charge but require a minimum of 2-weeks notice. If you’re part of a field trip, professional society, or area conference, tours are typically offered two days per week:

  • Tuesday and Thursday 10AM & 2PM

  • Not offered on statutory holidays

  • Guests are required to adhere to the safety information while on site.

We will do our best to accommodate special tour requests added to online bookings. Please direct additional inquiries to TRIUMF’s Strategic Communications team at
