Welcome to the home of the International Rock Flipping Day. IRFD is the second Sunday in September. It is a special day to get outdoors and flip over some rocks to explore the mysterious world beneath them.

We encourage everyone to bring along friends and family to flip those rocks.

Visit the Flipping page to learn more about how to flip rocks, including safety tips for you and the critters you discover.

Visit the History page to learn how this awesome day began and how it is evolving.

Post your pictures on our Facebook page or at the official IRFD Flicker page.
