Interstate Park Current conditions

Conditions as of Thursday, March 16, 2017:


Snow cover is minimal in the park right now, with most snow on north facing slopes or areas that are protected from direct sunlight. Expect trail conditions to vary from bare ground, to mud and water, and possibly some icy spots.

The Pothole, Summit, Echo Canyon and River Bluff trails are all great for taking in the scenic beauty of the St. Croix River Valley.

Nuthatches, chickadees, pileated woodpeckers and mourning doves, along with squirrels, have all been seen around the Ice Age Center bird feeders.

Deer have been seen browsing through out the park. Geese and other waterfowl have been seen enjoying the open waters of the St. Croix River along with several bald eagles. Sandhill cranes have been seen flying in the area as well.

Another cool phenomenon this time of year is maple sap icicle. These can be located on maple trees that have been damaged and the sap freezes at it leaves the tree.

Water has been shut off in the campgrounds but is still available at the Ice Age Center, the group camp hand pump, and at the old office building.

The dump station is closed for the season.


The small park office as you enter the park is now closed for the year. Please register for camping and pay for park stickers at the Ice Age Center. Ice Age Center hours vary during the week, but will be open 8:30 a.m. to 4 p.m. on weekends. If the Ice Age Center is not open, please self-register at the kiosk in front of the main doors.

River and lake

The St. Croix River is again flowing and is starting to rise with all the melting that has occurred recently. The Lake O’ the Dallas is still ice covered at this time. 

Please remember that ice conditions can change from place to place and from day to day. Park staff do not monitor ice conditions, thickness or safety. You must use your own judgment in deciding about venturing onto any ice. Tips on staying safe on ice.
