Two foreign tourists were seriously hurt abseiling a 150-metre cliff at Tat Mok Waterfall, Nam Nao, Phetchabun, on a Saturday. Local groups have petitioned the governor for a fact-finding panel to review safety equipment, operator qualifications, permits and emergency plans for high-risk activities. If you run or book adventure tours, expect tighter checks on permits, guide certification and equipment, and document your safety procedures now.
