About Californias Great America
About Californias Great America
California's Great America sits in Santa Clara, California, in the heart of Silicon Valley. It's a mid-sized park with a solid coaster line-up: Gold Striker (a highly-rated GCI wooden coaster), RailBlazer (a single-rail raptor coaster), Flight Deck inverted coaster, and The Demon. A Boomerang Bay water park operates on the same site in the summer.
Bay Area locals keep Great America steady year-round, with US school holidays and the WinterFest event driving the biggest crowds. Weekdays in April, May and September are dramatically quieter. Check live wait times for Gold Striker and RailBlazer on arrival, and use our crowd calendar to pick a quieter day - the park has been undergoing ownership and site changes that can affect operating patterns.
