Trail Tips:
• Footwear: Wear sturdy hiking shoes or trail runners to navigate soft sand and uneven root‑strewn forest paths.
• Water & Snacks: Carry at least two liters of water; there are no reliable water sources on the trail. Energy bars or trail mix make great fuel for dune climbs.
• Sun Protection: Bring sunscreen, sunglasses, and a wide‑brim hat—exposed dune tops offer little shade.
• Insect Gear: In spring and early summer, mosquitoes and ticks can be active; use repellent and perform a tick check after your hike.
• Leave No Trace: Pack out all trash, stay on marked trails to protect fragile dune vegetation, and respect wildlife by observing from a distance.

Trail Highlights:
• Dune Summit Views: The highest dune overlooks Lake Michigan shimmering against distant Chicago skyline on clear days.
• Wildflower Displays: Seasonal carpets of shooting star, Dutchman’s breeches, and purple coneflower brighten the understory and prairie.
• Birding Hotspot: Miller Woods is a magnet for warblers, vireos, and woodpeckers during migration; bring binoculars.
• CCC History: Interpretive plaques detail how the Civilian Conservation Corps helped plant beach grasses and build trails in the 1930s.

Additional Information:
• Trail Condition: Sand shifts seasonally—sections may be soft or firm depending on recent winds and precipitation.
• Restrooms: Portable toilets at the trailhead only; plan accordingly.
• Pets: Dogs on leash are welcome, but during peak bird nesting (May–June), consider leaving pets at home to minimize disturbance.

Enjoy the Paul H. Douglas (Miller Woods) Trail for a memorable journey across dunes, forests, and prairies—an Indiana Dunes gem that immerses you in both natural splendor and regional heritage.
