Dunes Pavilion

Dunes Pavilion is a long, restored Art Deco bathhouse just off the Lake Michigan shore inside Indiana Dunes State Park. It brings a beach café, event space, rooftop lounge, and visitor facilities together in one landmark. Keep it on your list if you're spending time at the state beach; this is a separate, state-managed park, so reaching the pavilion requires Indiana Dunes State Park admission.

The second-floor balconies face the shoreline, and the rooftop looks out across Lake Michigan. On clear days, visitors sometimes spot Chicago across the water, but the lake is the dependable view. From the beach, step back enough to frame the pavilion's repeated arches with a strip of water beyond; from the building, the long shoreline is the view to linger over.

The building was constructed in 1929 and is also dated to 1930 as its establishment year. It began as a bathhouse and restaurant, with restrooms and concessions for beachgoers; the rooftop originally served as an observation deck. The building still fills that beach-day role, even though its concessions and branding have changed.

The café and rooftop currently use the Jonna's Beach Café & Rooftop name. Food service is seasonal, rooftop service depends on weather, and pavilion hours can vary, so check before planning a meal or an upstairs visit. Snacks, beach supplies, ice cream, and public restrooms make it a useful service stop. Visitor reports on meal quality and wait times are mixed, so I'd treat the café as a convenient part of the beach day rather than the reason to drive out on its own.
