A view through time
On August 16, 1834, a young Charles Darwin ascended the 1,880-meter (6,168-foot) peak of Cerro La Campana. From the summit, he spent the day observing the landscape, which he described as seeing Chile "as in a Map." To the west lay the Pacific Ocean, and to the east, the snow-capped Andes. His detailed notes from this single day's climb provided a scenic description; they became an accidental scientific benchmark. Darwin documented the distinct zones of vegetation he encountered during his ascent, creating an ecological record that scientists now use to measure nearly two centuries of environmental change.
The mountain's name, La Campana, translates to "The Bell," a reference to its shape. Darwin's trek was arduous, following what he called "very bad" paths up the mountain. He noted the geology of "fragmented greenstone" near the summit and recorded the local method of extracting a honey-like sap from the region's famous palms. A plaque now commemorates his visit on the trail to the peak.
An accidental long-term study
La Campana National Park, established in 1967 and designated a UNESCO Biosphere Reserve in 1984, protects a unique Mediterranean ecosystem. Modern ecologists have returned to Darwin's notes, comparing his descriptions of plant communities to the present-day distribution. His 19th-century observations of vegetation boundaries align remarkably well with contemporary surveys, confirming the stability of these ecological zones over a long period. This offers a rare, high-quality baseline for studying the subtle effects of climate change.
The park contains one of the last major forests of the endangered Chilean Palm (Jubaea chilensis). This massive palm, one of the southernmost in the world, can live for over 1,000 years. Darwin would have passed through sclerophyllous forests, characterized by trees with hard, drought-resistant leaves like the peumo and litre. The park's varied topography creates distinct microclimates supporting a high diversity of life, including about 100 animal species. Mammals include the culpeo fox and the rarely seen puma, while birds range from the Giant Hummingbird to the Black-chested Buzzard-Eagle.
