The D-Day Adventure Park is located in the northeastern part of the state in Wyandotte, Oklahoma. Every year in June, the park hosts the world’s largest paintball event. Over 4,000 paintball players come from all over the world with around 20,000 people on site just to camp out and see the vendors that show up for the event. D-Day is designed to replicate and honor the actual D-Day of WWII. The world's largest paintball event is truly something you must see in person. The Adventure Park hosts other events as well, including bike and jeep rallies, 4x4 invasions, and an off-road race through the woods.
