The story

Flagstaff Festival of Science in Flagstaff

The Flagstaff Festival of Science fills ten days each fall with roughly one hundred free events, from open houses at observatories and research stations to guided hikes and hands-on demonstrations across northern Arizona. Established in 1990, it is billed as the longest continuously running, entirely free science festival in the world, drawing on Flagstaff's concentration of astronomical and scientific institutions.

Flagstaff has spent more than a century building a concentration of scientific institutions unusual for a city its size, anchored by an astronomy tradition reinforced over the twentieth century by federal research facilities and Northern Arizona University.

The place changes

02

The mystery stays covered

03

The city starts moving

Its 1990 founding predates most comparable American science festivals by more than a decade, and organizers describe it as the longest continuously running, entirely free science festival anywhere in the world, a claim rooted in the event's unbroken run and consistently free admission
