You stand at dawn on the two-lane road leaving Siem Reap, the highway unspooling toward the Dângrêk Mountains. The truck climbs, and palms and scrub give way to sandstone cliffs; the air sharpens with dust and distant chanting from village pagodas. Atop a 525‑meter escarpment, Preah Vihear’s tiers rise like a cluster of carved stones daring you to step closer.
