Glenwood Dunes Trail - 6.8mi Interconnected Loop

Snow covers the ground. A white and brown hut with a large opening provides warmth for skiers.

Interconnected loop system ranging from under 1 mile to 6.8 miles with extensions exceeding 15 miles. Mostly easy to moderate—flat sandy terrain with only 129 feet elevation gain—but 13 trail junctions demand navigation discipline and a paper map. Popular with hikers, runners, horseback riders, and cross-country skiers. Year-round hazards: ticks, poison ivy, mosquitoes (especially summer). Sandy sections offer minimal shade and rapid dehydration risk.

Facilities & rules

Restrooms At Trailhead: 1
Water Sources: Potable water at Glenwood Dunes and Calumet Dunes trailheads only. No water on-trail—carry 2+ liters minimum.

Safety & strategy

Hazards: Ticks
Poison ivy
Mosquitoes and flies
Disorientation at trail junctions
Sun exposure on sandy terrain
Loose sand (ankle twists)
Hazard Details: Ticks present year-round—use preventative clothing and check yourself post-hike. Poison ivy present on trail edges; stay on marked path. Summer months see intense mosquito and fly activity. With 13 junctions and minimal signage, navigation failure is real—bring a map. Loose sand increases ankle twists; sturdy footwear essential. Unshaded sandy sections cause rapid dehydration and heat stress.
Cell Service: Cellular service likely available but not guaranteed in all areas; do not rely on it for navigation. Carry a paper map and whistle.
Crowd Level: Moderate to heavy on weekends and holidays; lighter on weekdays
Peak Crowd Times: Weekends and holidays May-September. Mornings (6am-10am) less crowded than afternoons. Mid-week visits in shoulder season (April-May, September) offer solitude.
Best Season: May through October (stable weather, minimal snow). Horseback riding: March 16-December 14 (closed winter). Skiers: December-March (requires 3"+ snow).
Best Time To Visit: Late spring through early fall (May-October) for stable weather and moderate crowds. Start by 6am to beat midday heat on open sandy sections. Horseback riders: March 16-December 14 (closed if snow cover 3"+ before mid-December or after mid-March). Cross-country skiers: December-March with adequate snow depth.
Tips Advice: Bring a printed trail map—13 junctions are a navigation gauntlet without it.
Carry 2+ liters of water; sandy terrain has no shade on exposed sections.
Wear tick-protective clothing year-round (long pants, tucked shirt); check yourself post-hike.
Hike counter-clockwise as mandatory for horseback riders and skiers—follow it to avoid conflicts.
Start at Glenwood Dunes lot (US 20 & Brummitt Rd); parking fills by mid-morning on weekends.
Arrive by 6am for guaranteed spot on busy days.
Do not take the Glenwood Dunes Extension Trail if completing the main 6.8-mile loop (extension connects to railroad station; horses not allowed).

More details

Park Area: Central Indiana Dunes near Chesterton, IN
Trail Markers: Well-worn trail and junctions are marked, but with 13 junctions and multiple cut-offs, a printed paper trail map is essential. Available at trailhead kiosk or Indiana Dunes Visitor Center.
Dogs Allowed: Permitted on leash (6 feet or shorter) on non-equestrian portions of the trail. Prohibited on the main loop during horseback riding season (March 16-December 14) for rider safety.

Emergency Contacts: Emergency: 1-800-PARK-TIP. Non-emergency: https://www.nps.gov/indu/index.htm
Map Recommended: 1
Snow Dates: December-March typically. Horseback riding explicitly closed if 3"+ snow exists before December 15 or persists after March 15. Check NPS conditions before winter visits.
Mud Season: Spring (March-April) can be muddy; sandy terrain dries faster than typical eastern trails. After heavy summer rain, loose sections become sloppy. Peak mud: April-May.
Fall Colors Peak: October
Bug Season: Year-round tick risk. Mosquitoes and flies heaviest June-August. Protective clothing and insect repellent essential for summer visits.
Insider Tips: The Glenwood Dunes Extension Trail (2.6 mi) connects to Dune Park South Shore Railroad station—check train schedules if planning a multimodal trip. Horses NOT allowed on extension.
Dunewood Trace Campground Trail (4.4 mi round-trip) links to Dunewood Campground with mid-hike restroom resupply.
The cut-off at the east end near Calumet Dunes Paved Trail avoids a road walk.
Covered picnic shelters at Glenwood Dunes lot are first-come, first-served and popular—arrive early. Grills provided; bring your own charcoal.
Cross-country skiers: optimal with 3-6 inches of consolidated snow. Wait a day after fresh snow for packing.
Recent Updates: No major trail closures reported. Horseback season remains March 16-December 14 as of 2026. Check NPS.gov/indu for real-time conditions, especially in shoulder seasons.
Family Friendly Notes: Easy-to-moderate elevation makes it family-suitable, but navigation complexity (13 junctions) is a hazard for young children. Kids should stay close and be trained on trail awareness. Ground hazards: loose sand (ankle risk), ticks, poison ivy. Success: start early, bring extra water, pack snacks, and use a phone GPS app (AllTrails offline map) as backup to your printed map.
Review Summary: Hikers report 13 junctions are navigational chaos but manageable with a map and early start. Sandy terrain is easier on knees than rocky trails but demands extra water. Horse riders praise the dedicated loop and scenic dune landscape. Fall colors and year-round wildlife draw repeat visitors. Tick vigilance required year-round.

Frequently asked questions

Can I hike this solo, or is it too easy to get lost?

Yes, solo hikes are fine—just bring a paper map and plan counter-clockwise. Trail is well-worn and junctions are marked. Getting lost is a real risk only if you ignore the map; with it, you'll navigate confidently. Tell someone your expected return time.

Do I need special hiking boots for sandy terrain?

Not special, but sturdy and stable. Sandy sections demand good ankle support to prevent twists. Avoid minimal shoes; mid-height hiking boot or trail runner with good tread and ankle padding works well. Loose sand is slower—budget extra time.

How bad are ticks, really?

Year-round risk, but manageable. Wear long pants tucked into socks, long sleeves, and insect repellent (20% DEET). Check yourself every 2 hours on-trail and thoroughly post-hike. Early detection is key; remove with tweezers, not fingers. If tick-phobic, this trail demands discipline.

Is this okay for young children (ages 6-10)?

Yes, if coached on staying on-trail and drinking water regularly. Flat terrain and short-loop options (under 1 mile available) make it family-suitable. Risk: the 13 junctions confuse kids unless you're constantly orienting them. Use a phone GPS app (offline AllTrails map) as navigation backup. Older kids (10+) handle it better.

Will I get lost at 13 junctions without GPS?

Unlikely if you carry a printed map and study your route before starting. Use the map to identify landmarks (e.g., 'Turn left at junction after the bridge'). Mark your planned route on the map. GPS is a helpful backup but not essential.

Is this too easy if I'm an experienced hiker?

Probably yes, unless you value scenery, wildlife, or multi-use appeal. 129 feet elevation gain is minimal. Experienced hikers extend it with Dunewood Campground Trail (4.4 mi) or Glenwood Dunes Extension (2.6 mi) for 15-mile total. Visit in fall for peak colors. Challenge yourself with map-only navigation.
