The Minnesota DNR is warning hikers and mountain bikers that heavy rain during the month of May has washed out some trails. Boaters are also being warned that the state’s second-wettest May on record has created rising water levels at boat landings. Some parts of the state received more than a foot of rain during the last week of May, and DNR crews worked to fix damaged trails and roads. State park visitors should be prepared for high water levels, and drivers should avoid washed out roads. Authorities recommend that travelers check the DNR’s website to confirm whether recreational trails or forest roads are open.
