Much has changed here in recent years. The Douglas Environmental Education Center is now open daily to any who care to visit (not just groups) and the trail system features a delightful out-and-back all the way to Lake Michigan. There are two joined loops right next to the Education Center that offer 0.5- and 0.9-mile options through open dune oak savanna and passing by and through wetland areas. If you only have time for a short walk, I recommend hiking the two loops as a figure eight so you can cross the boardwalk shortcut twice. The trail to the lake joins the western loop near its northwest corner; walking to the lake and back will add about 2.6 miles to your trip. There are small climbs but overall, the tread is easy. It passes numerous small wetlands and a gorgeous inland lake, all the while giving no visual hint of the industrial colossi nearby.
