Indiana Dunes National Park: The Complete Visitor Guide

Indiana Dunes National Park is one of America's newest national parks (designated in 2019) and one of its most surprising: about 15 miles of Lake Michigan shoreline where 200-foot dunes meet beaches, bogs, prairies, and forest — all within an hour of Chicago and 25 minutes from our front doors in downtown Valparaiso. We've sent eleven years of guests to the Dunes; this is the guide we wish everyone read first.

First, the two-parks thing

There are actually two parks sharing the shoreline, and visitors mix them up constantly:

• Indiana Dunes National Park — the federal park, wrapping around the lakeshore in segments. National park entrance fees apply (an America the Beautiful annual pass covers it).
• Indiana Dunes State Park — a separate Indiana DNR park in the middle of it all, with its own gate fee, the famous swimming beach, and the 3 Dune Challenge.

Good news: they're minutes apart, and a great day uses both.

The beaches

• West Beach — the national park's most developed beach: lifeguards in season, bathhouse, and the Dune Succession Trail with its photogenic staircase over the dunes. Lots fill by late morning on summer weekends.
• Indiana Dunes State Park beach — the classic wide swimming beach beneath the big dunes; pair it with the 3 Dune Challenge.
• Porter Beach, Kemil Beach & the quieter access points — local-favorite stretches when you want sand without the scene. Parking is limited; go early or late.
• Sunset rule: any west-facing stretch near Mount Baldy delivers; on clear evenings you'll see the Chicago skyline floating across the lake.

The hikes

• The 3 Dune Challenge (state park) — the bucket-list one: roughly 1.5 steep, sandy miles over the park's three tallest dunes, topping out at Mount Tom (~192 feet). Short, legitimately hard, very satisfying.
• Dune Succession Trail (West Beach) — about a mile of stairs and boardwalk showing how bare sand becomes forest. The best effort-to-view ratio in the park.
• Cowles Bog Trail — the naturalists' favorite: ~4.7 miles through the wetlands that made these dunes scientifically famous, ending at a wild beach.
• Paul H. Douglas Trail (Miller Woods) — easy boardwalk-and-lagoon walk with dune views; great for kids and birders.
• Mount Baldy — the giant "living dune" that moves several feet a year. Summit access is ranger-led only; the beach below is open most of the year.

When to go

• Summer — peak beach season. Arrive before 10 AM on weekends, bring water for the dunes, and check beach advisories before swimming.
• Fall — our pick: warm lake into September, fall color over the dunes in October, empty trails.
• Winter — shelf ice turns the shore arctic and otherworldly (admire it from the beach — never walk on it), and you'll have the park nearly to yourself.
• Spring — one of the Midwest's best birding migrations rolls through the marshes; wildflowers follow.

Practical notes

• The national park charges a per-vehicle entrance fee (federal passes accepted); the state park charges its own per-vehicle gate fee.
• Check current hours, fees, and beach conditions at the official nps.gov Indiana Dunes page before you go.
• Cell service is spotty in the back trails — screenshot the trail map.
• Sand gets everywhere. Staying somewhere with in-unit laundry is not a luxury; it's strategy.

Where to stay: the Valparaiso play

Lodging immediately around the park is thin — a handful of motels and rentals in the small beach towns, which empty out at night. Downtown Valparaiso, 25 minutes south, is the comfortable base: a real walkable downtown for dinner after beach days, events most weekends, and our apartments with full kitchens, in-unit laundry for the sandy towels, free parking, and EV charging for the drive home. Here's how we'd structure the perfect Dunes day from Valpo.
