Nam Et-Phou Louey is situated midway between the ancient royal capital of Luang Prabang and the Secret War-era Viengxay Cave complex near the Vietnamese border. The winding ribbon of a road between the two showcases centuries of history with the remnants of stone age cultures, surprising ethnic diversity, and view upon view of rugged mountains and misty valleys. This route into a remote and forgotten world is studded with hot springs, gushing waterfalls, traditional craft villages and mysterious ancient standing stones, with the Plain of Jars not far away.
