Thailand's Department of National Parks launched 10 "Khon Doen Pa" (forest hikers) schools at national parks to train conservation-focused hiking instructors and educate visitors on responsible forest tourism. With over 10 million annual national park visitors generating 1,000+ tonnes of waste and ecosystem damage, the program shifts from reactive to preventive education using Leave No Trace principles. This supports Thailand's ecotourism growth while addressing sustainability challenges and raising nature-tourism standards.
