What Travellers Say
Reviews Summary
Visitors consistently praise the Glacial Grooves as a must-see natural wonder, highlighting their impressive scale and the educational value of the site. The surrounding natural beauty and the unique island atmosphere of Kelleys Island also receive high marks. Some minor critiques mention the seasonal nature of access and the potential for crowds during peak times.
"The grooves were carved by glaciers dragging boulders over the rock. The sign said they were almost 400 feet long, the longest example of glacial grooves that can be visited. There are some informative displays and a path around the grooves. It's a neat reminder of the size of the glaciers that once covered the area and geological time scales as those glaciers were able to slowly carve the grooves into the rock."
