The Glacial Potholes at Interstate State Park are a remarkable natural monument situated along the scenic Dalles of the St. Croix River, marking the border between Minnesota and Wisconsin. This unique geological site, with an elevation of approximately 219 meters, showcases the dramatic forces of nature that shaped the landscape over millennia. Located near the towns of Taylors Falls, Minnesota, and St. Croix Falls, Wisconsin, it forms a central part of the Saint Croix National Scenic Riverway and the Ice Age National Scientific Reserve.
Visitors are consistently captivated by the sheer scale and intricate detail of these ancient formations. The opportunity to walk directly among the more than 200 glacial potholes, peer into their depths, and even descend into some, offers a truly immersive experience. Many appreciate witnessing the tangible evidence of Earth's powerful geological history, making it a favorite for those interested in natural wonders and the dramatic effects of the last Ice Age.
As one of Minnesota's most popular state parks, the area around the glacial potholes can be quite busy, especially on weekends. However, even a short walk around the main pothole area is highly rewarding. Parking is generally available, but arriving earlier in the day can help avoid peak crowds. The terrain around the potholes is generally accessible for a short walk, but exploring further trails within Interstate State Park may involve varied difficulty levels.
The Glacial Potholes at Interstate State Park offer year-round appeal, with each season presenting a different perspective on the rugged landscape. Beyond exploring the potholes themselves, the park provides extensive hiking trails, such as the Pothole Trail, which winds through the formations and offers breathtaking views of the St. Croix River gorge. Other activities include scenic river overlooks, rock climbing on the basalt cliffs, canoeing, camping, and fishing, making it a versatile destination for outdoor enthusiasts.
These fascinating glacial potholes were formed approximately 10,000 to 11,000 years ago during the last Ice Age. As massive meltwaters from Glacial Lake Duluth surged through the St. Croix River valley, powerful whirlpools and eddies formed. Sand, gravel, and rocks caught in these swirling currents acted as natural drills, grinding cylindrical depressions into the hard basalt bedrock. Among the most famous is the "Bottomless Pit," a remarkable 60-foot-deep pothole, alongside others like "The Cauldron" and "Bake Oven," which visitors can explore.
The park's historical significance as the first interstate park in the United States, established by Minnesota in 1895 and Wisconsin in 1900, adds another layer to its appeal. Many historic structures, crafted in the 1930s by the Works Progress Administration and Civilian Conservation Corps using local basalt, blend seamlessly with the natural environment. Hikers often remark on the unique feeling of stepping back in time, both geologically and historically, while exploring the Dalles of the St. Croix.
Whether you're looking for family-friendly trails, a challenging hike, or simply a scenic walk to witness a geological marvel, Interstate State Park offers a variety of routes. You can discover the most popular trails and plan your visit by exploring the many options available on komoot, ensuring you make the most of your time at this extraordinary natural monument.

While the main Pothole Trail offers direct access to the most famous formations like the 'Bottomless Pit' and 'Bake Oven', many visitors also enjoy combining it with the River Trail for scenic views of the St. Croix River gorge. For a longer experience, the trails connect to the wider Interstate State Park network, including the western terminus of the Ice Age National Scientific Trail on the Wisconsin side.
Yes, dogs are generally welcome on leashes on most trails within Interstate State Park, including the areas around the glacial potholes. However, it's always a good idea to check the latest park regulations on the official Minnesota or Wisconsin DNR websites before your visit, as specific rules can sometimes apply to certain areas or during particular seasons.
A focused visit to the main glacial potholes area, including walking around and peering into the formations, can take anywhere from 30 minutes to an hour. If you plan to explore additional trails, enjoy the scenic overlooks, or visit the park's other attractions, you could easily spend half a day or more.
Parking is available at Interstate State Park, primarily on the Minnesota side near the main glacial potholes area. However, it is a highly trafficked park, especially on weekends and during peak seasons. Arriving earlier in the day, particularly before mid-morning, is strongly recommended to secure a spot and avoid the busiest crowds.
While the immediate area around some of the glacial potholes involves uneven terrain and stairs (like descending into the 'Bake Oven'), the park does offer some paved or boardwalk sections that provide accessible views. For specific information on accessible routes and facilities, it's best to consult the park's official website or visitor center.
Visiting in winter offers a unique and often less crowded experience. The potholes and surrounding cliffs can be beautiful with snow and ice. However, trails can become slippery due to ice and compacted snow, so appropriate winter footwear with good traction is essential. Some facilities or services might also be limited during the colder months.
Comfortable walking shoes with good grip are recommended, as the terrain around the potholes can be uneven and rocky. Layered clothing is advisable, as temperatures can vary, especially near the river. In summer, consider sun protection like a hat and sunscreen. For winter visits, warm, waterproof layers and ice cleats are highly recommended.
While the park itself does not have extensive dining facilities, the adjacent towns of Taylors Falls, Minnesota, and St. Croix Falls, Wisconsin, offer a variety of cafes, restaurants, and shops where visitors can find refreshments and meals before or after their visit to the glacial potholes.
The park's diverse habitats along the St. Croix River support various wildlife. Visitors might spot white-tailed deer, red foxes, and a variety of bird species, including bald eagles soaring overhead. Keep an eye out for smaller mammals and amphibians near the water and in wooded areas.
The most famous and concentrated collection of glacial potholes, including the 'Bottomless Pit' and 'Bake Oven', are primarily located on the Minnesota side of Interstate State Park. The Wisconsin side, while larger in acreage, offers different geological features, such as the western terminus of the Ice Age National Scenic Trail, and extensive hiking opportunities with stunning river views, but fewer prominent potholes.
Public transportation directly to Interstate State Park is generally limited. Visitors typically access the park by private vehicle. The park is located about an hour's drive from the Twin Cities metropolitan area, making it a popular destination for day trips by car.
