The Old Indian Trail and surrounding area in Sleeping Bear Dunes National Lakeshore is closed due to invasive hemlock woolly adelgid, the Park reported in a March 1 press release. Surveys this January and February found a large infestation on the southern boundary of the National Lakeshore, along and around the area of the Old Indian Trail. This infestation has prompted an area closure to slow the spread and allow for treatment. Plans are in development to reopen the trail by the fall of 2024.
