The Great Park is Irvine's most ambitious public space, built on the former Marine Corps Air Station El Toro. It mixes sports fields, lawns, playgrounds, public art, hangars, farmers-market events, and the orange tethered balloon that has become its visual shorthand.
The park is still evolving, so it can feel spread out and unfinished in places, but its scale is part of the story. It is best for families, cyclists, and anyone interested in how Orange County is turning military land into civic space.
