Dune Succession Trail

Overview

This compact interpretive loop at West Beach packs in a crash course on dune ecology with a punchy stair climb and rewarding lake views. It’s a 1.0-mile total loop (not one-way) that showcases the four stages of dune succession—from open, shifting sand near the shoreline to older, shaded forest inland. Expect a mix of scenery in a short distance: beach, open dunes, jack pine and cottonwood stands, and marshy edges near Long Lake.

Route and Terrain

Start from the large West Beach parking lot and head toward the bathhouse to pick up the signed loop. The route immediately tackles a long staircase—about 270 steps—with roughly 75–80 feet of elevation gain and short stretches near a 15% grade. From the high point, you’ll get sweeping views over Lake Michigan and, on clear days, a peek at the Chicago skyline. After the overlook, the path rolls through sand, boardwalks, and packed sections as it winds through forest and wetland before closing the loop back to the lot.

What You’ll See

This is the park’s signature spot to watch dune succession unfold in real time: bare foredunes, stabilized shrub zones, and mature forest all in one loop. Keep an eye out for seasonal wildflowers, butterflies in warmer months, and active birdlife—especially around Long Lake and in the trees along the back half of the loop. The beach sits right next to the trailhead, making an easy post-hike cool-down.

Difficulty and Crowds

It’s short but moderately challenging because of the stairs and soft sand. Most active kids and adults can handle it, but the staircase will get your legs’ attention. This is a popular walk, and the bathhouse/parking area can be busy on fair-weather weekends; go early or late for cooler temps and fewer people.

Tips and Tricks

• Footwear matters: sand gets into shoes and can make footing slick on steps when wet.
• Sun exposure is real on the dunes—bring a hat, sunscreen, and water.
• Respect roped and signed areas; the dunes are fragile and easily damaged.
• Open year-round, but steps and boardwalks can ice over in winter.
• West Beach is a fee area; bring your park pass. If you want more mileage, this loop can be combined with the other West Beach loops.

Best Time to Hike

April through October is prime for comfortable temps, wildflowers, and migratory birds (spring and fall). For photography and cooler conditions, aim for early morning or late afternoon when the sun is lower and crowds thin.
