Start with Indiana Dunes State Park 3 Dune Challenge Trail while the light is softer and the heat has backed off a bit. This is the classic short-but-serious dune workout: expect steep climbs, soft sand, and big views over Lake Michigan if you’re willing to pace yourself. From most places around the dunes, you’ll want to drive to the Indiana Dunes State Park entrance off IN-49 and plan on parking fees if you don’t already have the state park pass. Give yourself about 90 minutes so you’re not rushing the climb; it’s one of those hikes that feels much harder than it looks, so wear shoes you don’t mind filling with sand and bring water even in the evening.
After the hike, head west to West Beach for an easy wind-down on the sand. It’s one of the best spots in the area for that wide-open dune-and-water view, and the shoreline here feels expansive in a way that makes you forget how close you are to Chicago. From Indiana Dunes State Park, it’s a short drive along IN-49 and then local roads into the West Beach area; just keep an eye on the parking lot hours and gate times, since the beach access can be more limited than the daylight suggests. Then continue to Porter Beach for a quieter sunset stop — less bustle, softer atmosphere, and usually a nice last look at the lake without feeling crowded. It’s the kind of place where you can just sit for a bit and let the day settle.
For dinner, make the easy drive into Chesterton and stop at Cafe 339. It’s a relaxed, small-town spot that’s dependable after a sandy, active day, with comfort-food kind of energy and a price point around $15–25 per person. If you’re coming straight from the beach, it’s an easy transition on local roads and usually a straightforward parking situation downtown. No need to over-plan this part — just eat, sit down for a minute, and enjoy being off your feet.
If you still want one last stop, finish at Brown Truck Brewing in Chesterton for a low-key beer before calling it. It’s a good local hang with a laid-back crowd, and a pint or two usually lands in the $8–15 range. Since you’re only doing one night, keep the evening loose and don’t feel pressured to stay late — the whole point is that you’ve already had the dunes, the beach, and the sunset in one clean, satisfying day.
