Baxter State Park officials have opened additional trails to the summit of Mount Katahdin as well as all major campgrounds in the wilderness park.
Park rangers on Saturday opened Chimney Pond campground to overnight guests roughly two weeks later than usual because of lingering snow and poor trail conditions.
Three of the four major trails leading from Chimney Pond to the peak of Katahdin – the Dudley, Cathedral and Hamlin Ridge trails – are now open to hikers.
Park Director Jensen Bissell said the fourth route, Saddle Trail, will probably remain closed for at least another week because of snow.
Spring has come late to Baxter State Park and other parts of far northern Maine following heavy snowfall amounts during the winter.
