After several days of exploring the UNESCO World Heritage town of Luang Prabang, the lure of the great outdoors took me thirty kilometers south to the village of Long Lao—the home of the Hmong indigenous people of Indochina. Accompanied by three other staff members from Tiger Trail Adventure, our truck set off under the misty fog of the early morning. After an hour of driving through small settlements and along a long stretch of rough road, we reached the trekking jump-off point for Kuang Si Falls under a still gloomy sky.
