GRAND CANYON, Ariz - Recent heavy monsoonal rainfall has caused damage to portions of the South Kaibab Trail approximately one-half mile below Cedar Ridge and to the North Kaibab Trail below Supai Tunnel.

Both trails remain open to foot traffic but are currently impassible to livestock. The park does not expect to complete trail repairs for stock use until early October. Officials remind hikers to use caution when hiking into the canyon on any trail during and after heavy rainfall. Rockslides, mudslides, unstable footing and flooded washes are just a few of the obstacles that hikers may encounter along the trail.

Forecasters are calling for more rain this week across parts of the Kaibab Plateau, which could lead to additional trail damage and will also create wet and muddy trail conditions and a greater chance of slips, trips and falls. Rainfall-caused rockslides can also cause damage to the park's water pipeline that serves the corridor trails; therefore, hikers should always bring a method to treat water.

Hikers are asked to use caution when hiking on any trail in the park, to consider physical fitness and ability and always check the status of trails before beginning a hike.
