Between Chicago & Milwaukee Is Illinois' Beach State Park For Family Fun On Lake Michigan

If you're looking for a family getaway outside of Chicago or Milwaukee, you won't have to go far. While this part of the country has incredible water parks to splash the day away, there is something to be said for enjoying the great outdoors and the beach. Just south of the Wisconsin state border, nestled against Lake Michigan, lies Adeline Jay Geo-Karis Illinois Beach State Park, where you'll find 6 miles of sandy beaches, oak savannas, marshlands, and two nature preserves that set the scene for a plethora of outdoor family activities to get away and recharge from busy life in the city. 

While the Great Lakes region is full of charming destinations for a fun getaway, Illinois Beach State Park stands out for its unique natural environment, having the only remaining section of beach ridge shoreline in the state. Powerful waves, currents, and wind from the lake transformed rocks into tall sand dunes. Grasses sprouted atop the dunes, and wetlands formed below. While hiking, biking, fishing, or boating, you may see hundreds of (sometimes rare) species of native plants and birds.

The state park is located outside of Zion, Illinois, about an hour north of the Loop and south of Milwaukee. Both O'Hare (ORD) and Milwaukee Mitchell (MKE) international airports are less than an hour's drive away. If you'd rather go car-free, take the Union Pacific North line between Chicago and Kenosha; the train has stops in Zion and Winthrop Harbor, just outside of the park, and bicycles are allowed on board. Once you arrive at the park, entry is free for day-use visitors.

Illinois Beach State Park has plenty of opportunities for fun in the sun. The 4,160-acre state park covers two areas, a north unit and a south unit, which have distinct activities for your family outing. If you're looking to explore some of the natural environment without major crowds, you'll likely want to visit the north area. Take a short walk around Sand Pond, where you may spot geese, turtles, and amphibians lazing the day away, or explore the 1.8-mile-long Camp Logan Trail, which passes a well-preserved military training facility built prior to the First World War, as well as excellent bird habitat. If you're itching to get onto the water, head to the North Point Marina at the very northern edge of the park. The massive marina — the largest on the Great Lakes – has a boat and watercraft launch along with a nautical-themed bar and restaurant and serves as a base for chartered fishing trips on the lake. Based on our research, there are no watercraft rentals on site.

If you're looking for a fun day splashing on the beach, you'll likely want to visit the south unit, where you'll find more beach parking and amenities, including the park's visitor center and seasonal store. Unlike other beaches around Chicago, these are the only fully natural beaches in the state – and they don't typically draw the crowds you'd find at the city beaches (though note that there are no lifeguards on duty). Unlike swimming at one of the cleanest lakes in the U.S., it's a good idea to first check the Lake County Health Department's website for any public health advisories and bacterial outbreaks at the lake before swimming. Visitors who would rather stay dry or not risk getting sick can toss a line in the water and fish for salmon, trout, or perch, though not around swimming areas. Visitors who have bikes can quickly zip between the two areas via the 2-mile Zion Bike Trail.

Illinois Beach State Park is open year-round and offers different family-friendly activities throughout the year. During the spring or summer, join a beach clean-up or a hike with a naturalist through the park's nature center. Fall activities have included guided hikes, as well as Fall Nature Fest, held in October. Visitors can also utilize the park's Camp Logan Trail for cross-country skiing during the winter months, though the nature preserves are closed during this time.

Visitors looking to spend the night in the park will have several options. The park's campground, located in the south unit, has 241 individual campsites with electricity and access to water and shower facilities. Camping is available during the spring, summer, and fall, and reservations are recommended in advance. If your family would rather not camp, the Illinois Beach Hotel, the only hotel on the beach in the state, is open year-round and just a stone's throw from other attractions in the park. The hotel features a swimming pool (under renovation, as of this writing), a restaurant, and a bar. If you stay when the restaurant isn't open, or you're looking for a home-cooked breakfast while camping, Emily's is less than 10 minutes away by car. Other nearby food options include authentic barbecue at Honey Bay's BBQ, or pizza and a cold beer at Bert's Pizza Pub and Gaming. Each restaurant listed has hundreds of five-star reviews on Google Maps. 

Besides its beaches and the towering skyscrapers of Chicago, Illinois is also noted for being one of the friendliest states in the country, according to a 2026 study by SmartAsset. To experience the charm of the "Land of Lincoln" on a personal level, visit some of the friendliest towns in Illinois.
