“We are visiting California for the holidays and we figured we should come out here and have fun,” tourist Tanya Zivkovic said.

Those same signs are now posted along the Chimney Rock Trail.

Wet weather is partially to blame.

Park rangers are asking hikers to follow the signage and stay safe on the trails.
