Dividing Chicago's Logan Square and Humboldt Park neighborhoods, The 606 is a former industrial rail line that's been transformed into a nature trail and a public space. In addition to being an excellent place to enjoy the outdoors, the 2.7-mile-long park hosts an assortment of events and shows for visitors to experience.

Recent travelers loved that The 606 has a variety of access points, which means visitors can explore the trendy western Chicago neighborhoods that the park borders. Physically active reviewers also suggest travelers complete a run, walk or bike ride along the length of the trail. (Divvy, Chicago's bike-share program, has a station near the park.)

The park is open year-round from 6 a.m. to 11 p.m. and is free to access. During the winter, the Chicago Park District will remove snow to keep the center of the trail clear until the area's first significant snowfall (ranging from 3 to 6 inches). At that point, the snow will be left to promote winter activities like snowshoeing and cross-country skiing.
