Yes, on a 6-foot leash or shorter. Watch for poison ivy exposure and heat stress on the open beach section. Bring extra water for your dog—sand is hot and dehydrating.

Paul H. Douglas Trail - 3.4mi Moderate Hike

Q: Is poison ivy a real problem?

Yes. Poison ivy lines the trail edges. Stay single-file on the narrow path. Wear long pants and boots. Wash thoroughly with soap and cold water immediately after hiking.

Q: How bad are the ticks?

Year-round presence. Use permethrin spray on clothing and a tick repellent on skin before the hike. Check yourself thoroughly immediately after and again 12 hours later. Remove ticks with tweezers, pulling straight out.

Q: Is the sand really that much slower?

Yes. Sand hiking burns energy fast and adds 1–2 hours to your pace. A fit person might do 3 miles per hour on firm ground but only 1.5–2 mph in deep sand. Budget 3–4 hours for this 3.4-miler.

Q: Do I need a map and permit?

No permit needed, but a map helps at trail junctions. Free maps are available at the trailhead kiosk and Paul H. Douglas Center. Park entrance fee ($25 per vehicle) is required.

Overview

About This Trail

A 3.4-mile out-and-back through wetlands, globally rare black oak savanna, towering sand dunes, and Lake Michigan shore. Trail traverses diverse habitats with spring wildflowers and wildlife viewing, but the loose sand footing and full-sun beach section make this harder than the distance suggests. Expect slower pace, significant exposure, and abundant poison ivy along narrow sections. Not for the time-crunched—sand adds 1–2 hours to the official 2-hour estimate.

Highlights

Difficulty Level

Moderate

Trail Highlights

Lake Michigan shore views framed by towering sand dunes, globally rare black oak savanna with native grasses and lupine wildflowers (spring/summer peak), wetland complex with wildlife viewing, river crossing, habitat diversity

Insider Tips

• The sand is deceptive: official time is 2 hours, but sand hiking burns 1–2 extra hours. Budget 3–4 hours total. • Look for beavers in the wetland complex on the first loop section. • The Grand Calumet River bridge marks a dramatic landscape shift into towering dunes—terrain changes here. • Don't stop at the first lake view. Walk to the actual beach for the payoff—towering dunes framing Lake Michigan are the real prize. • May–June wildflower bloom is peak—plan for maximum color if hiking then. • Beach weather can swing 20+ degrees from the woods. Wear layers you can shed. • Stay single-file through narrow oak savanna sections to protect fragile lupine habitat and avoid poison ivy.

Best Season to Hike

Hiking Tips

Bring at least 2 liters of water—sand hiking dehydrates faster than normal terrain
Tuck pants into socks or apply permethrin spray to clothing—ticks are present year-round
Stay single-file on narrow sections to avoid poison ivy lining the trail edges
Wear sunscreen and a hat—trail starts shaded but ends in full sun
Tighten your boots well—sand will work its way in and cause blisters
Plan for slower pace: sand hiking takes 1–2 extra hours versus hard-pack terrain
Use trekking poles for stability on loose dunes
Carry a map—trail has junctions that benefit from confirmation

Family Info

Trail has poison ivy edges and narrow single-file sections—keep children on path and supervise closely. Sand surface is slow for young legs; plan extra time. Grand Calumet River bridge crossing is secure. Full sun on beach section creates heat stress for kids—start early and bring triple water. Easier 0.9-mile center loop (30 min, easy difficulty) available as warm-up or alternative.

What Hikers Say

Hikers praise the habitat diversity and Lake Michigan views but consistently warn that sand footing slows progress significantly—expect 3–4 hours, not 2. Most report needing more water than typical trails. Poison ivy and ticks are regular complaints; preparation (long pants, repellent, careful boot fit) matters. Spring wildflower bloom draws repeat visitors.

Can beginners do this hike?

Yes, if you're fit enough for a moderate 3–4 hour walk. The 3.4 miles is short, but sand makes it harder. Start early, bring double water, and don't rush. The easy 0.9-mile Paul H. Douglas Center loop (30 min) is a good warm-up first.
