Stretching across eight US states and the Canadian province of Ontario, the Great Lakes are huge inland seas containing 21% of the world’s surface fresh water.
The five lakes — Superior, Michigan, Huron, Erie and Ontario — were carved out by retreating glaciers some 10,000 years ago and are connected to the Atlantic Ocean via the Saint Lawrence River. They have long been a major transportation route for industrial materials such as iron ore, coal and limestone.
However, in stark contrast, the lakes also provide crucial wildlife habitats and are a scenic backdrop for a wide range of outdoor activities such as kayaking, diving, boating and fishing.
Visitors are struck by the clarity of these pristine waters, the silence of the forested wilderness and the variety of wildlife to be seen, from moose, deer and migratory birds to bears and eagles.
It's easy to explore some of the thousands of tranquil lighthouse-peppered islands while the quaint towns and resurgent cities provide vibrant nightlife and dynamic museums, and are greatly influenced by the lakes themselves.
Best time to visit the Great Lakes
The climate of the Great Lakes region ranges from extremely cold winter temperatures, regularly as low as minus 30°C (minus 20°F), to pleasantly hot, humid and sunny summers.
The best time to travel is during the spring and autumn (May, June, September, October) but be aware of mosquitoes during June.
