Calm or dancing waters surrounded by shades of green, the St. Croix National Scenic Riverway provides 252 miles of recreational opportunities. Canoe amid the northwoods, where wolves, deer, otter and porcupine can be seen or boat surrounded by wooded bluffs and historic towns. The Wild and Scenic Rivers Act of 1968 created a thin narrow corridor of protection for the St. Croix and Namekagon Rivers. This corridor provides scenic views and a haven for wildlife. The clean, sparkling river water shelters native mussels, dragonflies, and fish. Overhead, eagles, osprey, kingfisher and warblers fly and nest. Closer at hand raccoons, fox, and bear may be glimpsed. Color bursts forth from trilliums and marsh marigolds, followed by asters, cardinal flowers and the changing fall colors. A wealth of wildlife viewing awaits those who seek it. A glimpse of the River's past can also be seen on the landscape. A stone wall, a steel ring, a cabin or a metal bridge recalls earlier times. Dakota, Ojibwe, voyageurs, loggers and settlers have all known this river.
