Gigantic Bicycle Festival is the Pacific Northwest’s annual summer celebration of bicycle culture.

The festival weekend features live music, film, visual & performance art, cyclocross, road & trail rides, hand build bicycles, guest speakers, sculpture, and interactive installation.

The festival weekend opens with camping and outdoor movies Friday evening. A supported road ride with Century, 50, and 20 mile routes departs from the festival grounds Saturday morning. Festival goers spend the weekend camping, exploring the Snoqualmie Valley by bike, and taking in an impressive music lineup, outdoor movies, art and installation.
