Andrews Park

Fantastic park across the street from the Norman Public Library. Andrews has been around for years and hosts many festivals and events throughout the year. There is an amphitheater, playground, picnic and party shelters, a jogging course, basketball court and decent parking for a park of this size. The splash pad is very popular and fun for kids. There are restrooms on premises, but I am pretty sure they are only open in the warmer months.
You can rent the shelters for parties or gatherings, but I am not aware of the cost. To do so, you need to contact the city. But, I have been to events at Andrews and had a great time. There is a jogging track that circles the park which is nice. My boy loves the playground and splash pad. Highly recommended for those with kids or who like to jog or walk in a nice outdoor space.
