Kayaking along Pictured Rocks National Lakeshore, Upper Peninsula, Michigan. I did this for vacation last year. It's an eight hour day trip along the Pictured Rocks. Breath taking and well worth the money you spend on the experience!
Kitch-iti-kipi (Big Spring) | Palms Book State Park | Upper Peninsula | Michigan | Large spring-fed lake. The water is so clear you can see details in the lake all the way to the bottom. This was absolutely stunning! Visited September 2013
