Not very far from Cave Lodge, the river flowed into the mouth of Tham Lod, or “through cave.” On bamboo rafts illuminated by lanterns, guides were ferrying a mix of Thai and foreign visitors into the five-story opening. I kayaked beneath the gaping entrance and, as the last rays of natural light faded behind a bend, switched on my headlamp. The interior of Tham Lod was over 100 feet wide in some places, its ceiling covered in long stalactites mottled by the reflections of the water below.
In the middle of the cave, we pulled up to a gravelly beach and set off on foot.
