May: Paseo Arts Festival- Taking place every Memorial Day, the festival is marked by the parade of works by the city's best visual artists, and some of it's favorite musicians. It's really family friendly.
June: Red Earth Native American Cultural Festival- About 1200 Native American dancers and visual artists gather every year to celebrate their unique indigenous culture. Over 30,000 people turn up to see the Red Earth Parade annually.
October: Oktoberfest- The city takes the festival quite seriously and spends the whole month celebrating it in one way or the other. Here, it usually begins on Labor Day weekend. The food, beer and music is pretty traditional.
December: Victorian Christmas- Like a few other cities around USA, dressing up Dicken's style, taking historic home tours, browsing antiques during Victorian Walk Evenings and checking out the Victorian-era Main Street at Har-Ber Village’s 19th Century Christmas on Main Street celebration is par for the course. Unmissable on your travel vacation itinerary planner to Oklahoma City.
