The waterfall is part of the Ciletuh-Palabuhanratu Geopark, which features some of the oldest rocks in Java.
The cliffs surrounding the fall are composed of breccia and sandstone formations dating back to the Paleogene period.
Cimarinjung is one of several waterfalls in the Ciletuh basin, all fed by the same regional watershed system.
The local rock formations are referred to by geologists as the Jampang Formation, showcasing deep-sea sedimentary deposits uplifted by tectonic forces.
Curug Cimarinjung is a prominent 100-meter-tall tiered waterfall located within the Ciletuh-Palabuhanratu UNESCO Global Geopark in West Java. The waterfall is characterized by its dramatic position between prehistoric megalithic boulders and volcanic rock cliffs. Water flows directly into the Cimarinjung River, which subsequently discharges into the Indian Ocean at Palangpang Beach. The site is a key geological element of the Ciletuh amphitheater, a basin formed by ancient tectonic shifts. The volume of the water is significantly influenced by rainfall, making it a seasonal attraction that can diminish during extended dry periods. The area is accessible via a short hike through local agricultural fields and riverbanks.

Wear water-resistant footwear with strong grip, as the terrain around the boulders is slippery.
Bring a waterproof bag to protect electronics from heavy mist and spray near the basin.
Visit during the early stages of the rainy season to see the falls at peak volume while avoiding the peak of the monsoon's muddy conditions.
Do not swim directly beneath the base of the falls due to falling debris and strong underwater currents.
Water flow is minimal or non-existent during the peak of the dry season.
Respect local farming boundaries; dress conservatively as this is a rural village area.
