Located on the heart of Olds, Centennial Park is a family friendly park since it is built around a skate park and a splash pad. Beyond those two main features, there is also a gazebo, lots of picnic tables and benches, and numerous historic monuments and interpretive signs scattered throughout the park.
There's a picnic shelter with a wood stove and BBQ, but it's only available by reservation; so make sure you call ahead if you want to make use of them.
