Don't walk on the rocks at the edge of rapids.

No, and you really shouldn’t try. Those rocks are usually slippery from spray or algae, and the drop-offs are sudden—sometimes right where you think the shelf is solid.

The “warnings about slippery surfaces and sudden drop-offs” exist because people get hurt doing exactly this. A misstep means a fall into fast, cold water that can pin you against rocks or sweep you downstream before anyone reacts.

I’ve seen parks put up signs for a reason. They aren’t being overprotective. The rock that looks dry might be wet, and the edge that looks gradual might be a six-foot ledge. If you want a view, stay on the designated overlooks or marked trails.

Your phone pic is not worth a broken leg—or worse.
