Description - There is so much to do at Interstate State Park, located on the beautiful St. Croix River. Visitors can climb the cliffs of the St. Croix River Dalles, canoe the flat-water, watch kayakers rush through the rapids, or relax on a excursion boat. Spring brings a great diversity of wildflowers and in fall, the St. Croix River Valley forest is ablaze in the autumn colors of red, gold, and orange. The geology that formed this park intrigues visitors, and brings geologists from all over the world. At least 10 different lava flows are exposed in the park, along with two distinct glacial deposits, and traces of old streams valleys and faults. During the summer, hike the trails and explore the glacial potholes that make this park unique.
- Creeks and springs that flow into the St. Croix River support white-tailed deer, skunks, raccoons, squirrels, and many different birds. There are many places in the park to listen for bird songs and owl calls.
The park's landscape is diverse and includes floodplains and forests of hard maple, oak, and pine. Many rare and endangered species are found in the park. For a small, highly visited area, Interstate is a haven to these unique species. Historically, small gardens were planted in the pothole area in the early 1900s. The park is restoring these gardens for visitors to enjoy.
Recreation - Visitors can climb the cliffs of the St. Croix River Dalles, canoe the flat-water, watch kayakers rush through the rapids, or relax on a excursion boat.
Climate - Minnesota lies so far north that winter is the longest season of the year. There are many recreation pursuits to enjoy during this season, but be sure to dress appropriately so that you can enjoy them. Temperatures often dip below freezing during winter and the state receives an average of 50 to 60 inches of snow. Spring, summer and fall can be very wet and rain gear will be necessary for travel during these seasons. Spring and fall tend to be shortened with variable weather, due to long winters, but offer less crowded trails and campgrounds. Summer temperatures average between 70 and 85 degrees F. Night time temperatures dip near 55 and a light jacket is recommended. July and August are the height of the tourist season.
The park is approximately 45 miles northeast of Minneapolis/St. Paul on U.S. Highway 8.
