The famous Blue Whale roadside attraction on Route 66 is in Catoosa, Oklahoma.
The Blue Whale of Catoosa is a large blue concrete whale built in the early 1970s by Hugh Davis as a gift for his wife, Zelta. It stands in a pond beside the historic Route 66 corridor and became a memorable roadside attraction for travelers.
The structure was originally part of a private swimming and picnic area. Over time, the whale became more famous than the surrounding recreational site and developed into one of Oklahoma’s best-known Route 66 landmarks.
Tulsa is nearby and is a major city along the Oklahoma route, while Claremore is another important northeastern Oklahoma stop. The attraction’s name itself supplies the precise answer: it is the Blue Whale of Catoosa, not the Blue Whale of Tulsa or Claremore.
