The Apostle Islands are a group of twenty-one wild islands scattered across Lake Superior in far northern Wisconsin. They are known for sea caves, sandy beaches, and old lighthouses.
They are most famous for the glittering sea caves, which turn into sparkling ice caves during very cold winters. Kayakers paddle through the caves in summer while eagles soar overhead.
Waves have carved arches, tunnels, and hidden rooms into the red sandstone cliffs. In summer people kayak through them, and in cold winters they freeze into icy wonderlands.
Lake Superior is the largest freshwater lake in the world by surface area and stays cold and clear. Its deep blue water surrounds every island like a giant inland sea.
The islands are home to black bears, bald eagles, and many kinds of birds. Boat tours let families watch for animals along the quiet, forested shores.
