Insider tip — Nam Phu Ron Pong Deud — 'boiling spring' in Northern Thai — emerges from the volcanic terrain of Mae Hong Son Province near the Myanmar border. The sulfurous geothermal vents create a dramatic landscape of steaming channels and mineral-encrusted rock. Local hill tribes have long used the springs for cooking and bathing. The remote jungle setting, accessible via mountain roads from Mae Hong Son town, rewards adventurous travellers with an authentic thermal encounter.
