The story of Isla Grande de Chiloé begins with the **Huilliche and Chono peoples**, who inhabited the region long before the arrival of the Spanish in the 16th century. These Indigenous communities built their lives around fishing, shellfish gathering, and forest products, creating traditions that continue to influence Chilote culture today. When the Spanish arrived in 1567, they founded the city of Castro — now one of the oldest continuously inhabited cities in Chile.
The blending of Indigenous and European cultures produced the distinctive **Chilote identity**, with its own forms of craftsmanship, legends, agriculture, navigation techniques, and religious syncretism. Today, visitors to Isla Grande de Chiloé still witness this blend in the island’s wooden architecture, language, cuisine, and festivals.
Isla Grande de Chiloé spans roughly **8,400 square kilometers**, making it the second-largest island in South America after Tierra del Fuego. The island features rolling green hills, dense temperate rainforests, dramatic coastlines, wetlands, fjords, and traditional fishing villages scattered along its shores. Much of its landscape is shaped by the **Pacific Ocean**, which influences everything from climate to food to daily life.
The climate is cool, rainy, and oceanic. Expect frequent mist, fog, and unpredictable showers — a hallmark of the Chiloé experience. These conditions support lush vegetation, especially the evergreen forests found in the national parks.

The island is famous for its **wooden churches**, constructed between the 17th and 20th centuries using local timber and Indigenous carpentry techniques. These churches symbolize the fusion of Jesuit mission architecture with Chilote craftsmanship.
Most notable churches:
Castro, the island’s capital, is known for its colorful **palafitos** — houses built on stilts over the water. These iconic structures illustrate how locals adapted to tidal environments. The town also offers vibrant markets, seafood restaurants, and artisan workshops.
Located on the western coast, Chiloé National Park protects pristine rainforests, dunes, wetlands, and wildlife-rich habitats. Visitors can spot sea lions, foxes, whales, and dozens of bird species. Hiking trails such as the Cole-Cole route offer breathtaking views of the Pacific.
These traditional towns provide markets filled with handicrafts, wool products, ceramics, and smoked seafood. Ancud also hosts the **Fort of San Antonio**, an old Spanish defensive fortification.
A short trip from Ancud leads to Puñihuil, one of the few locations in the world where **Humboldt and Magellanic penguins** coexist. Boat tours operate seasonally and allow close observation of these charismatic birds.
One of the most captivating aspects of Isla Grande de Chiloé is its rich mystical folklore. Chilote mythology weaves together stories of ghost ships, shapeshifting creatures, witches, and forest spirits. These legends were historically used to explain natural phenomena and reinforce community values.

Chilote cuisine is deeply tied to the sea, the forest, and one extraordinary ingredient: **the Chilote potato**, which has more than 200 native varieties. Fishing communities prepare hearty dishes that reflect centuries of maritime tradition.
In markets like those in Castro and Dalcahue, you’ll find smoked mussels, giant sea urchins, king crab, and freshwater fish sourced from the island’s wetlands and rivers.
