Malaysia’s government is tightening hiking rules nationwide after a social media trend left increasing numbers of adventurers needing to be rescued when they became lost or stranded in remote locations. The new measures include making guides mandatory in 189 high-risk locations, strengthening pre-climb screening measures and banning some compressed hikes. Compressed hikes have been banned at many high-risk mountainous areas across the country, Syed Ibrahim Syed Noy, the deputy minister of natural resources and environmental sustainability, told the upper house of Malaysia’s parliament on Wednesday. Hikers underestimating the importance of preparation and being driven by social media trends have increased the risk of emergencies, said Syed Ibrahim, whose comments were published by Malaysian national news agency Bernama. Syed Ibrahim said the government was also strengthening pre-climb screening measures by requiring health declarations, medical history checks and insurance coverage.
