When was Cedar Point established?

Cedar Point was established in 1870, which aligns with the correct choice. This year marks the opening of Cedar Point as a beach resort and amusement area located on a peninsula along Lake Erie in Ohio. Over the decades, Cedar Point has evolved from its early days as a small leisure destination into one of the most renowned amusement parks in the world, known particularly for its collection of roller coasters and thrilling rides. The significance of its founding year emphasizes Cedar Point's long history and development within the amusement park industry, making it an important cornerstone in the evolution of roller coasters and themed entertainment.

Though other years are close, they don’t accurately reflect the year Cedar Point was established, making 1870 the only correct answer in this context.
