Silver Beach Amusement Park
Located just across a park from Silver Beach, this one-block area is a children’s wonderland: They can ride the hand-carved wooden horses on the Silver Beach Carousel, or spend hours running around the play spaces and interactive exhibits at the Curious Kids’ Museum and Discovery Zone.
Warren Dunes State Park
If you haven’t had enough beach time — or you’d like to wander along a bigger expanse of it — Warren Dunes offers three miles of shoreline, as well as hiking trails that snake through the wetlands. If you hear excited screaming, look up to see kids who have climbed to the top of a 250-foot sand dune flying down. Some even hang-glide from the top.
Boating
St. Joseph is located on the mouth of the St. Joseph River, and watercraft rentals are plenty and varied: Steer a kayak up the river, picnic on a pontoon, or take a speed boat for a spin out in the lake. You can also find jet skis, paddleboards, and even a paddleboat designed for big groups.
