Summer Solstice Walks
Celebrate the official first day of summer with a guided summer walk at the Spiro Mounds Archaeological Center. Constructed by Natives more than 1,000 years ago, the mounds offer a unique glimpse into ancient Oklahoma while the tour guide brings the stories surrounding their past to life. The tours run at 11am, 2pm and 7pm, and each one covers about a mile over the course of two hours. Each tour is available for $5 for adults and $3 for children in addition to the Center’s daily admission fee.
