Royale is surrounded by deep blue waters of Lake Superior, the largest freshwater lake on Earth. The only way to get there is by boat or sea plane. The National Park Service operates shuttle boats that take visitors to Isle Royale. The boats leave from two Michigan ports. A boat trip to Isle Royale takes three to five hours. Waters are often extremely rough.

　　Modern copper mining began in the late 1800s, resulting in large areas of the island being burned. This led to settlement development. Soon, Isle Royale became popular for summer homes. It became a national park on April 3, 1940. In 1980, officials named it an International Biosphere Reserve(生物圈保护区)because of its unique ecosystem.

　　Isle Royale offers hiking, camping, boating, and even scuba diving. The National Park Service protects 11 sunken(沉没的)boats for divers to explore. They are reminders of Lake Superior's commercial shipping history. The sunken wooden ship called The America is one of the most popular dive sites. The America carried passengers, mail, and supplies to many towns along the shores of Lake Superior. It first launched in 1898, and was used until 1928, when it was damaged. It sank to the bottom of the lake soon after.

　　Visitors to Isle Royale share the trails with a well-studied population of wolves. Scientists believe wolves walked there during a freeze of the lake sometime in the 1940s. Researchers closely record their population numbers. Much of the research takes place during the winter, when the trees are bare. The researchers fly over the island to observe the animals from above.

　　Animal research is the only winter activity going on at Isle Royale. The national park is closed each year in late October because of the terrible weather conditions and reopens in spring time the next year.

　　But for the other months of the year, Isle Royale offers green forests, and clear blue waters. Its excellent scenery and unusual location keep visitors returning year after year.
