Snake Road Closes Through October for Annual Migration

WOLF LAKE – Park Rangers are reminding drivers that Forest Service Road 345, also known as Snake Road, is closed to all traffic through the end of October to ensure safe crossing for several species of snakes and amphibians during their critical time of migration.

The 2.5-mile-long road closes the week of September 1 through October 30 to allow snakes and amphibians – some considered threatened and endangered in Illinois and the United States – to migrate from their summer habitat in the LaRue Swamp across the road to their winter habitat in the limestone bluffs.

The gradual, two-month migration event attracts visitors from across the country. About 66 percent of the amphibians and 59 percent of the reptiles known to occur in Illinois are found here.

Though the road is closed to vehicles, it is open to visitors traveling on foot. Special regulations apply to the area.
