Interstate State Park.

A Brief History of Interstate State Park

Interstate State Park in Taylor Falls, Minnesota was first established in 1895, making it the second state park after Itasca State Park was established as the first in 1891.

The park was named Interstate State Park because it was the first state park to cover two different states. The adjoining Interstate State Park just across the St. Croix river in Wisconsin was established in 1900.

Late in the 1800s citizens from both states wanted to preserve the area around the St. Croix river from the threat of mining. The states worked together to establish the parks and protect the beautiful natural resources and habitats that exist within the parks. Today the two state parks operate separately and each offers unique sights, hiking trails, and experiences.

Visitor Center and Gift Shop

The visitor center and gift shop are great places to start, especially on your first visit to Interstate State Park. Inside you’ll find all kinds of useful information like trail maps, trail updates and closures, as well as general information about nature and wildlife in the park. There are exhibits to help you learn about the geological history and other unique features of the park.

The visitor center is located at 256 Traprock Street near the glacial potholes area. The Glacial Potholes Trail is a great place to start after you check out the visitor center, it’s an easy half-mile loop with scenic views of both the St. Croix river and the potholes. The trail is somewhat uneven in places but there are handrails and metal walkways to help you through the rougher parts of the trail.

After your day exploring the park, stop back by the visitor center before you leave to visit the nature store gift shop if you’d like to purchase a gift or find a souvenir to take home with you.

Things to See at Interstate State Park

There is no shortage of beautiful sites at Interstate State Park. Here are just a few of the things you can see on your visit.

Glacial Potholes

Glacial potholes are a unique geological phenomenon formed by melting glaciers. They are often formed next to a boulder or other obstruction where quickly flowing glacial melt water once formed a whirlpool, swirling rocks, sand, and water around and carving out the potholes we see today.

Interstate State Park is home to the largest explored glacial pothole in the world. You can see the giant pothole plus several others for yourself on the Glacial Pothole Trail. The potholes range in size from one foot to sixty feet deep.


There are several overlooks to visit at the park on the River Trail and the Sandstone Bluff Trail. The overlooks offer stunning views of the valley and the St. Croix river below. They are well worth a hike up to the viewpoints.


In the 293 acres of the park, there are many plants and trees including pine, maple, and oak forests that are a beautiful sight, especially in summer when the trees are lush and full, and in the fall when the leaves start changing color turning into a beautiful autumn display.

In spring and summer, colorful wildflowers transform the park with beautiful blooms. The wildflower checklist on the park’s website shows you what wildflowers are in bloom each month from April to September.

Animal Life

There are many different animals that make their home in the park including white-tailed deer, raccoons, skunks, frogs, over 200 species of birds, and more.

The St. Croix river that runs along the edge of the Minnesota side of the park is home to a variety of fish and mussels.

Hiking at Interstate State Park

There are four hiking trails to choose from at Interstate State Park. Each offers scenic views of different areas of the park and ranges from half a mile to one and a half miles one way.

Potholes Trail

The Potholes Trail highlights the park’s glacial potholes, a unique feature of the park that you don’t get to see just anywhere. It’s well worth a visit to check out the ancient potholes.

On the trail, you’ll even get to climb thirty-five feet down into the Bake Oven pothole using a staircase to explore the inside of the pothole. The pothole gets its name because of the way it opens from the side, resembling an old stone oven. The side opening makes the perfect place for guests to walk in and explore.

River Trail

The River Trail includes several scenic overlooks. It’s a great place to look for birds like great blue heron, turkey vultures, and bald eagles.

Sandstone Bluff Trail

The Sandstone Bluff Trail is the most challenging trail at the park. This one-mile trail includes steep up and downhill sections and over 200 stairs. The trail passes by walls of sandstone and ends at the bluffs overlook with stunning views of the St. Croix Valley below. From the overlook, you can easily see Wisconsin across the St. Croix river

Railroad Trail

The Railroad Trail follows the former route of the Northern Pacific Railroad and offers views of sandstone cliffs and interesting rock formations.
