The windows, in detail.
We list only timing NPS publishes for Indiana Dunes. The park gives a fall migration, a festival weekend in May, and night-sky conditions, but no spring migration dates, no wildflower season, and no time of day for the skyline view, so we don't give those. Most public areas open at 6 am and close at 11 pm, West Beach and Porter Beach close at 9 pm, and only Kemil Beach stays open all night (NPS hours page).
| Subject | Window | Notes |
|---|---|---|
| Fall bird migration | Fall | NPS says southbound birds follow the north-south shoreline in fall and are funneled into the Indiana Dunes. You can watch hawks during migration from the top of a sand dune, waterfowl from the shoreline with a spotting scope, and wetland birds in what's left of the Great Marsh (NPS bird watching page). The Great Marsh Trail is a popular feeding and resting area for migrating wetland birds, with an accessible trail to a marsh overlook. On September 21 the sun rises at 6:35 a.m. at the visitor center. |
| Indiana Dunes Birding Festival | Third weekend in May | The park plays an important role in the annual festival, a four-day event with expert-led outings at dozens of birding spots around the region. The sun rises at 5:23 a.m. on May 21. Portage Lakefront and Riverwalk, with its universally accessible pier, is also a good bird-watching spot (NPS accessibility page). |
| Chicago skyline from West Beach | Clear days; West Beach open 6 am to 9 pm | NPS says you can hike the Succession Trail to the top of a dune at West Beach and look over the land and Lake Michigan to the Chicago skyline (NPS places to go page). West Beach is open from 6 am to 9 pm. At the visitor center the sun sets at 8:26 p.m. on June 21 and 4:21 p.m. on December 21. |
| Night sky at Kemil Beach | Clear, moonless nights; open 24 hours | Kemil Beach and its lot are open 24 hours a day, between Indiana Dunes State Park and Beverly Shores, which NPS calls the 7th designated International Dark Sky Community in the world. NPS says stars and the Milky Way show best on clear, moonless nights, so check the moon's phase and rise and set times. Light from nearby towns makes some parts of the park darker than others (NPS stargazing page). |
| Northern lights | Rare; slightly better odds in winter | NPS says the park occasionally sees the aurora borealis, and chances increase slightly in winter because there are more hours of darkness. Its stargazing page shows the aurora over Lake Michigan at Kemil Beach on October 10, 2024. |
| Winter birds and shelf ice | Winter | Open water and miles of shoreline draw large numbers of wintering birds, and NPS names visitors such as the dark-eyed junco and snowy owl. West Beach, Kemil Beach, Dunbar Beach, and Lake View are good for winter scenery, and the dune shapes show more clearly with the plants dormant. Shelf ice often forms along the lake in cold weather. Photograph it from solid ground and never walk on it (NPS winter activities page). Our Indiana Dunes in winter page covers the season. |

Crowds in the photo months.
July is the busiest month at about 510,000 visits. May, the festival month, runs 57% of that, September 53%, and October 42%. January is the quietest at 15%, and NPS says crowds are never an issue in winter.
No entrance fee is owed just to drive through, but it applies once you stop to walk a trail or use the beach; our Indiana Dunes fees page has the prices. Month tradeoffs are on the best time to visit Indiana Dunes page.
Rules for drones, permits, and the shore.
Drones are prohibited: launching, landing, or flying an uncrewed aircraft in the park is banned unless the superintendent approves it in writing (NPS superintendent's compendium).
Most photography here needs no permit. Under the EXPLORE Act, NPS says filming, still photography, and audio recording by eight or fewer people need no permit or fee when the work stays in areas open to the public, uses hand-carried equipment only, doesn't need a site to itself, doesn't harm the park or other visitors, and won't add costs for the park. Commercial shoots, content creators, students, and media are treated the same. A bigger group, or a shoot that misses any of those conditions, may need a permit, which carries location fees and a non-refundable application payment of $65 for simple activities or $200 for complex ones, so contact the park first. Apply at least 30 days and up to 12 months ahead. A photography workshop run as a business may need a commercial use authorization. The entrance fee still applies either way (NPS permits and reservations page).
After dark, use only red lights, not white flashlights, headlamps, or phone screens, since eyes take 20 to 30 minutes to adjust. Don't trample vegetation, and wear closed-toed shoes. Overnight camping isn't allowed along roadsides or in parking lots. By day, hike in the center of trails, and watch for rip currents on Lake Michigan in summer (NPS safety page).
