Welp, that's a tour that those kayakers will never forget.

A tour group of kayakers were paddling near the Pictured Rocks on Monday afternoon when a large section of the cliff broke off and fell into the water.

The tour guide said that some smaller rocks had fallen into the water earlier and they thought they were far enough away to be safe.

The video was taken from a pontoon boat; the man taking the video flew the drone closer to the cliff to make sure that everybody was okay after he heard screaming.

That video is ABSOLUTELY INSANE. How scary!
