The Great Falls Balloon Festival is a hot air balloon festival held in the twin cities of Lewiston and Auburn, Maine. It has been held annually each August since 1993, although it was only held virtually in 2020, due to the COVID-19 pandemic. The festival, which is held on the banks of the Androscoggin River attracts up to 100,000 spectators each year. The festival features rides, games, music, and trade booths in the various parks and plazas where the balloons lift off.
