The management board said it had received reports of rocks tumbling from the mountainside onto the trail, posing a serious danger to hikers. The steep terrain and loose rocks mean even minor disturbances could trigger rockfalls.
Visitors have been advised not to use the trail to ascend or descend the mountain.
Instead, the management board recommended the Power Line Trail, saying it is more frequently used and easier for rescue teams to access in an emergency.
Tourists were also urged to avoid unofficial trails and refrain from pushing or dislodging rocks that could endanger people below. Any safety hazards or incidents should be reported immediately to the authorities.
The warning follows similar advice issued in April, when visitors were urged to limit hiking during the rainy season because of slippery conditions, landslides and unstable weather.
The management board said using designated trails would improve visitor safety and enable rescue teams to respond more quickly in emergencies.
