Interstate State Park

The air carries a crisp, pine-scented promise as you approach Interstate State Park along Milltown Road, the river’s steady murmur threading through the trees. Early morning light filters through towering pines and rugged cliffs, casting dappled shadows on the mossy ground beneath your feet. The park’s signature rock formations rise abruptly from the St. Croix River, their striated faces telling tales of ancient glaciers and rushing waters. Here, the quiet is punctuated by distant calls of songbirds and the occasional splash of a fish breaking the surface, setting the tone for a day steeped in natural wonder.

Explorers find plenty to engage their senses, from the winding River Trail that stretches a little over a mile each way, offering a mix of gentle hiking and scrambling over boulders for the daring. The park’s namesake Glacier Potholes beckon near the parking area, where swirling waters carved deep, polished holes into the rock, creating miniature pools that glisten under the sun. Kayaks can be rented at the river’s edge, inviting visitors to paddle alongside towering cliffs and glimpse the intricate geology up close. A boat tour lasting around 80 to 90 minutes drifts downriver, weaving history and natural science into the journey while showcasing the area’s dramatic bluffs and unique rock formations.

Camping here blends rustic charm with thoughtful amenities that enhance the outdoor experience without overshadowing it. The sites, framed by dense woodlands and the distant river’s gleam, offer privacy and a sense of seclusion. Morning showers deliver steady, warm water that refreshes after trail adventures, and clean facilities maintain a welcoming atmosphere. Day-use picnic areas scattered throughout the park invite leisurely lunches beneath the canopy, while well-maintained trails accommodate both beginners and seasoned hikers eager to test their skills on varied terrain. Friendly staff are often spotted offering tips on trail conditions or the best spots for fishing along the riverbanks.

Evening settles quietly over Interstate State Park, and the soundscape shifts to the rustle of leaves and the gentle lapping of water against stone. Campers return to their sites, drawn back year after year by the blend of rugged beauty and accessible wilderness. The park’s layers of rock, water, and forest hold stories that unfold slowly—stories that call visitors to come back, to wander, climb, and listen once more.
