Turnip Rock has been deemed one of the Amazing Rock Formations in America by CNN. Indeed it's one of the most photographed attractions in the Upper Thumb. However, the unique rock formation is located on private land and is considered part of the Pointe Aux Barques cottage community.
Access to Turnip Rock is only available as a guest of a member of the Pointe Aux Barques community or if you access by water with a kayak or canoe. That being said, you must stay in the water or right along the edge of the water.
As soon as you attempt to climb up the famous rock or its equally favorite neighbor, the "thumbnail," you're trespassing on private property. Even worse, the entire formation is subject to extreme conditions and tends to weather, crumble, and fall apart. Climbing will undoubtedly cause some minor but real damage. It would quickly add up if everyone did it. In addition, you will likely end up arrested and having to spend some time in Bad Axe at the county jail. Which would blow up your good time.
It is best to follow Leave No Trace principles as a good steward of the environment. Besides, the real trick is to get a great shot of the formation at sunrise or sunset.
