I-95 mom, Marianna Frances of Port. St. Lucie says, "A favorite place for Jensen Beach moms is Indian Riverside Park. There is plenty of room to run around on beautiful days, bring your friends, have a picnic, and play in the fountain, and it's all free."
The park backs up to the Intercostal and the Children's Museum of the Treasure Coast. Marianna says you'll have plenty to do to pretty much last all day.
