TRIUMF public tours

Discover TRIUMF!

Thousands of people come to visit Canada's national lab for particle and nuclear physics and accelerator-based science each year.

All that you need to bring on your visit to TRIUMF is genuine curiosity for the world around you!

What can I expect to see?

TRIUMF is home to the world's largest cyclotron particle accelerator, energetic isotope beams, and a host of nuclear health facilities.

Guests are taken on top of the cyclotron and through experimental buildings by real students and researchers. Expect to get an inside look at what the lab is really like! Tours last 75-minutes, and photography is encouraged.

Drop-in tours

We offer drop-in tours throughout the year, free of charge. Drop by TRIUMF's main office building lobby before 1 pm to ensure your spot! All guests are required to read our safety information before coming on the tour.
