“Crowded and taciturn, high-tech and ancient, crafted and pristine,” writes Christina’s, the Marble Mountains “stand as a bridge leading us from the present to the past.” This “cluster of five marble and limestone hills” named after the five elements -- Kim, Thuy, Moc, Hoa and Tho … metal, wood, water, fire and earth -- “expresses part of our Vietnamese history and culture.” The Marble Mountains (Ngu Hanh Son or “Five Elements Mountains”) are “full of caves, tunnels and Buddhist shrines just waiting to be explored,” says Nomadasaurus.
“The caves within the mountains hold many secrets,” says Vietnam Guide, “including bullet holes from when troops used to spy on the US soldiers relaxing on My Khe Beach below and buildings standing within the caves and grottoes.” There are also Buddhist sanctuaries and places of worship “dotted across the mountains” of this “much-visited spiritual site,” and there’s even a “special circular cave.” Plus “spectacular panoramic views” at the summit. And don’t miss “a huge cave known as Am Phu,” advises Atlas Obscura -- “deep inside is a re-creation of a Buddhist hell where sinners confess crimes, suffer punishments, and hope to reach heaven’s light.”
