When you are in Yuma, you must visit the West Wetlands Park for a picnic, or a walk or to watch your children play. The park is 110 acres and is located along the side the Colorado River.
Centennial Beach is at the East end of the park. You can picnic and swim or launch your boat (or paddle board) here. It's also a great spot for a dog to go for a little swim.
There is a section of the park is dedicated to the history of Mormon Battalion of volunteers from the Church of the Latter Day Saints. They were instrumental in the annexation of southern Arizona and southwest New Mexico on June 8, 1864.
