Big Dipper is a wooden roller coaster at the old Geauga Lake amusement park in Bainbridge Township, Ohio. Built in 1925, the Big Dipper is an ACE Coaster Classic and an ACE Coaster Landmark. However, the award was never officially presented to the park. Until September 2007, it was the oldest operating wooden coaster in Ohio, and the 7th oldest operating roller coaster in the USA (12th oldest in the world).

It is currently Standing but not operating since Cedar Fair closed and dismantled Geauga Lake Amusement Park in 2007. Cedar Fair sold and destroyed every ride in the park, except The Big Dipper. Geauga Lake was a Northeast Ohio destination since 1887.

Being the oldest operating roller coaster in Ohio, many are concerned about the fate of Big Dipper. Even though the coaster had been declared 'sold' numerous times, all of the deals fell through. There is still no official word from Cedar Fair what is going to happen to the Big Dipper.

The Big Dipper needs to be given the recognition it deserves as an ACE Coaster Landmark and also an Ohio Historical Site. Cedar Fair should refurbish the ride and restore it to working condition to preserve it's rich history.
