The site was officially declared a Nature Sanctuary (Santuario de la Naturaleza) by the Chilean government in 1990.
The geological composition includes sandstone and limestone layers that contain fossilized remains of marine invertebrates from the Neogene period.
It acts as a strategic observation point for spotting Humboldt penguins and various species of cormorants.
The promontory effectively splits the coastal currents, which contributes to the specific sedimentary patterns of the nearby dunes.
Roca Oceánica is a designated Nature Sanctuary located on the coastal border between Concón and Viña del Mar, Chile. The site features a prominent rocky promontory characterized by significant geological formations that provide a habitat for diverse coastal bird species. Elevated observation paths allow visitors to view the Pacific Ocean, the Aconcagua River mouth, and the surrounding coastline. The area is composed of fossiliferous limestone and quartz-diorite rocks dating back millions of years. It serves as a natural barrier against heavy surf, playing a critical role in local marine ecosystem preservation.

Wear footwear with high-traction soles to navigate the uneven, weathered rock surfaces.
Bring windproof outer layers, as coastal winds remain strong throughout the year.
Stay strictly on marked paths to protect the fragile cliff-top vegetation and geological features.

Maintain silence to avoid disturbing nesting seabirds; pack out all personal trash.
