The Iron River originates in northwestern Wisconsin's Bayfield County and flows northward for approximately 30 miles before emptying into Lake Superior near the town of Iron River. This cold, clear stream drains a watershed of roughly 100 square miles within the heavily forested Chequamegon-Nicolet National Forest. Paddlers will find the Iron River offers an enjoyable mix of quiet flatwater sections interspersed with occasional Class I-II rapids, making it suitable for novice to intermediate canoeists and kayakers. The upper reaches feature a narrower, more intimate setting winding through dense woodlands, while the lower river widens as it approaches Lake Superior.

Several access points allow for day trips of varying lengths. A popular 7-mile stretch runs from County Highway A to Highway 2, passing through a scenic gorge with modest rapids. More experienced paddlers can tackle the entire river over 2-3 days, camping at primitive sites along the banks.

Spring and early summer typically provide the best water levels for paddling the Iron River. By late summer, low water can make some rapids too shallow to run. The river is generally ice-free from April through November.

Wildlife is abundant along the Iron River. Paddlers may spot bald eagles, osprey, otters, and deer. The river supports a healthy population of brook and brown trout, making it popular among fly fishermen as well.

Key landmarks include the Iron River Falls, a series of small cascades near the town of Iron River, and the historic Iron River Fish Hatchery, established in 1892. The river played an important role in the region's logging history, with remnants of old splash dams still visible in some locations.

Access points with parking are available off County Highways A, H, and 2. The town of Iron River serves as the primary gateway community, offering lodging, supplies, and shuttle services.

Paddlers should be aware of woody debris creating potential strainers in some sections. Life jackets are required by law. Anglers need a Wisconsin fishing license and should check regulations, as special rules apply to this designated trout stream.

The Iron River provides an excellent opportunity to experience the natural beauty and rich history of Wisconsin's Northwoods region via a scenic and manageable waterway.
