Penang Hill has been hit by landslides after several days of rain, Malaysia's The Star reported.
At least 13 locations in and around the hill were affected.
Bukit Bendera MP Zairil Khir Johari said soil erosion had occurred in several areas along the jeep trail, causing trees to be uprooted.
"Fortunately, there were no casualties.
We advise the public to practise extreme caution when within the affected areas.

Mr Zairil added that repair works would take about four months.
"This problem has also resulted in the cost of the remedial works to escalate to RM1 million (S$385,500) for each location," he said.
Mr Zairil said that the area along the KM2.5 had been cordoned off for safety reasons.
