Explore. Educate. Connect.

The Lee and Rose Warner Nature Center is a private educational institution. Our Trailside Museum, classes, and events are open to the public. For safety and conservation reasons, we do not permit self-guided hiking on our trails.

We sincerely apologize for the recent problems with our summer camp registration process. The Science Museum of Minnesota's website is currently experiencing significant technical issues with the website host. Due to these problems, we had to shut down registration last week and we will not be able to continue online registration this season.

Beginning Thursday, February 26 at 9 a.m., we are continuing registration via fax at (651) 433-2430 or drop-off in person at Warner. We will not be accepting registrations via email or phone. If the camp is full, your child will be put on a waitlist as waitlist spots are available.

A list of camps that still have spots open, as well as waitlist opportunities, is listed on our summer camps page to help you plan your registration. If your child is placed in a camp or on a waitlist, you will receive an email confirmation. If after two weeks you have not received an email confirmation, please feel free to call us.

If you successfully registered for a camp and received a confirmation email within the last week, your registration is still valid.

We sincerely apologize for this unfortunate situation. We hope you continue to support Warner Nature Center and appreciate your patience while we address this problem.


Located 30 miles northeast of Saint Paul near historic Marine on St. Croix, Warner is the oldest private nature center in Minnesota and features over 600 acres of undeveloped woodland, marsh, lake, bog and grasslands. Within the Trailside Museum, visitors can learn about our public natural history programs, learn how to become a volunteer or Friend of Warner, and experience the Hidden Wonders of Warner, our brand-new interactive, hands-on education exhibits.
