Mountain biking and hiking activities have been suspended due to the closing of Lion's Head and the Glen footpaths, following the wildfire that spread along Tafelberg Road in Cape Town on Sunday.South African National Parks (SANParks) has requested residents to practice extreme caution during the rest of the fire season, after approximately 60 hectares of vegetation were burnt, and a number of cars and apartments damaged. Seven fire fighters are receiving treatment after they were injured while trying to put out the fire.According to SANParks, the rapid spread of the fire was caused by the unpredictable weather conditions.
