04 · The parks

What each one is.

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.

The park combines a theme park with a marine-animal section, running coasters like Medusa (the West Coast's first floorless), Kong (an inverted coaster), Superman: Ultimate Flight, Joker 4-D Free Fly Coaster, and the newer DC Stunt Coaster. Dolphin, sea lion and bird shows run throughout the day.

Bay Area weekend visits, California school holidays, and the Fright Fest event drive Discovery Kingdom's peak crowds. Weekdays in April, September and October are dramatically quieter, with queue times on most rides staying short. Check live wait times for Medusa and Superman on arrival, and use our crowd calendar to pick a midweek date for shorter waits. The bayside setting makes for pleasant walking even on quieter days.
