To some, it’s the official kick-off to the Kentucky Derby Festival. To others, it’s the unofficial beginning of spring. But to all, it’s simply one of the largest annual fireworks shows in North America and the setting for some of the most memorable moments you’ll ever share. What started with 3000 shells at a local stadium is now the nation’s largest annual fireworks extravaganza held at the junction of two states at a bend in the Ohio River. You can do a lot more at Thunder Over Louisville than simply look to the sky. With a slew of entertainment options available on the ground, there is sure to be something for everyone! From the Thunder FoodFest to the Interactive Display Area to the Kid’s Play Areas on the Great Lawn, there’s refreshments and entertainment galore. When it gets dark, the Thunder rolls. With an estimated average attendance of half a million people, it has become the largest annual event in its region. The show continues to be the largest annual pyrotechnics display in North America thanks to the artistry of Zambelli Internationale and the production of Visual Presentations.
