The El Dorado Frontier Theme Park will transport your kids back to the Wild West! From panning for gold to a 3-mile train ride through history, El Dorado Frontier Theme Park is a not-to-be-missed hidden gem in Long Beach. Located within the El Dorado Park East, in Long Beach, California, our California Gold Rush-themed park is open on weekends and we're a great alternative event rental destination for a unique and unforgettable birthday party for your child! We also have seasonal events like our Halloween Pumpkin Patch and our Winter Wonderland, where Santa himself appears (along with real snow!). Remember to enter through the El Dorado Park entrance on Spring and drive through the park under Wardlow Street and through to the other side.
