Interstate State Park should be on every Minnesota hiker’s springtime bucket list. This petite park packs much adventure into it’s 295 acres, one of the states smallest state parks. The rugged terrain and plentiful views of rivers, rapids, a waterfall, cliffs and unusual landscape make this park seem more vast than a scant 295 acres.
Quick Review: 7/10 Interstate has much to offer. We were surprised by the amount of activity in this park. Great for a day trip of adventures, the trails are rough, needing some trail maintenance. Overall a very entertaining little park.
Interstate State Park was the first state park to coincide with another park across state lines. Interstate State Park is also Wisconsin’s first state park established. The Minnesota portion is just under 300 acres, but the Wisconsin side contains 1330 acres. The WI park also has an informative video, nature center and more than 9 miles of hiking trails. The Minnesota side only has 4 miles of trails.
Not the kind that wreck your tires. These are actually quite neat. The holes formed when glacial rivers tore through the area of rough basalt rock. The rugged terrain combined with rushing water created whirlpools and eddies that wore away the rock, creating the holes we see now.
The holes and other unique rock formations are strewn about the ridges and cliffs along the St. Croix River. Interstate State Park actually has the deepest explored pot hole in the world, at 60 feet deep. There are railings and pathways, but still, keep children in hand.
Hiking Trails & Curtain Falls
The mileage at this park tops out at 4. That’s a pretty scant amount of miles for a Minnesota state park, but this park makes those miles count.
Sandstone Bluffs Trail: The most unique hiking trail in the park, aside from the pot holes area, is the Sandstone Bluffs Trail. This hiking trail leads hikers to a spouting waterfall called Curtain Falls. The best time to see this falls is in the spring when water levels are higher and the snowmelt is feeding the creek. During drier months, the falls may only be a trickle and the creek is all but dry. For an in depth guide on the hike to Curtain falls check out Spring Hike to Curtain Falls.
Spring & Fall
The best time of year to visit this park is in the spring, in my opinion. The amount of visitors is still low and the waterfall will be flowing at Curtain Falls. Be warned; there may be ice yet on the trail and the cliffs and bluffs are steep. Check the DNR webpage for trail conditions before venturing out in the spring to avoid icy conditions.
Return in the fall for amazing colors and dramatic cliff views over the St. Croix. I love autumn hikes and this park was beautiful in late September. The conifers contrasting with the autumn leaf changes is stunning.
Camping & Lodging
Camping is available between April and October. Which makes sense, the parks icy surface and close proximity to a surging St. Croix make Interstate more dangerous in the colder months of the year, but a gorgeous oasis in the summer.
The great thing about this park is that it’s dog friendly! The dogs are allowed on all trails and shorelines, but not in buildings. Our Xena loved exploring the park with us, both in the spring and fall.
St. Croix River
The St. Croix River separates our Interstate State Park from Wisconsin’s Interstate State Park. The river can be explored along the park shores, personal watercraft with an access at the southern parking area, or via a third party tour or rental service.
Taylors Falls Scenic Boat Tours offer a variety of tours along the St. Croix river and departs near the visitors center at the northern parking area. Canoes and kayaks are available for rent along with a shuttle service. (Also dog friendly on some tours, check site FAQs for more details.)
Climbing the cliffs is an option for the experienced rock climbers out there. This is a climb at your own risk situation, and the park does not offer a guide service or equipment. Permits are required at no cost and can be obtained at the park office.
