Scientific & Natural Areas are public lands set aside due to their ecological or geological diversity and importance, and are open to foot traffic all year-round. They were new to me, so maybe are new to you, too.
There are many of these areas throughout Minnesota, including several in the Twin Cities metro.
They sound like amazing places to get out and enjoy nature without the crowds!
Scientific & Natural Areas allow hiking, cross country skiing and snowshoeing. While there aren’t any maintained trails, that’s not an issue when it’s snow-covered! In fact, if you love getting away from the bustle of urban life, these Natural Areas may be just the thing.
Another plus with using them during the snowy months—you don’t have to worry about damaging the plant life or dealing with bugs!! Big plus.
There are quite a few restrictions when visiting these areas to keep them as undisturbed as possible. Please read this page on the Minnesota DNR site before visiting.
It lists which ones are best for hiking, which ones allow dogs and guidelines for bringing them along, areas recommending for wildlife and bird watching and much more. It’s a great resource!
These Natural Areas can be found on this map.
