Even after there is enough snow to use the trails, the DNR warns riders to be careful as trails may have debris across them, unfrozen swamps, rocks, or standing crops.
There are around 22,000 miles of snowmobile trails in the State of Minnesota. Nearly 21,000 miles of those trails are maintained by local snowmobile clubs.
Snow depth and trail conditions are reported on the DNR website.
