Chiloé Island is a large, rectangular landmass in southern Chile. 

The island has two very different sides. The western side is a wild and rainy place. It is home to the Valdivian temperate rain forests. These are some of the few temperate rain forests in the world. The mountains run like a spine from the northwest to the southeast. The western shores are rocky and mostly straight. In contrast, the eastern shores have many bays and peninsulas. The eastern side is warmer and much drier because of the mountains. Most of the towns and cities sit on this eastern side. 
People have lived on Chiloé for a very long time. The first humans arrived more than 7,000 years ago. They were nomadic groups who hunted and fished for sea creatures. You can still see ancient waste heaps called middens along the coast.
History has shaped the island in many ways. The Spanish founded the city of Castro in 1567. Later, Jesuit missionaries arrived and built many wooden chapels. Today, there are more than 150 traditional wooden churches on the islands. Many of these are recognized as World Heritage Sites. 
Nature lovers can find many amazing animals near the coast. The waters are home to blue whales and sei whales. You can also see Chilean dolphins and sea lions. 
Chiloé Island is a major landmass located in southern Chile. 

The island's landscape is shaped by distinct geographic features. It is roughly rectangular in shape. A belt of mountains runs from the northwest to the southeast. The northern mountains are known as the Cordillera del Piuchén. The southern mountains are the more subdued Cordillera de Pirulil. The western half of the island is a wilderness. It contains contiguous forests and swamps. The northeastern side features rolling hills. These hills contain a mosaic of pastures, forests, and cultivated fields. The western shores are rocky and relatively straight. The eastern and northern shores are more complex. They contain many inlets, bays, and peninsulas. 
Climate plays a huge role in how the island looks. Chiloé has a cool temperate oceanic climate. It also follows a Mediterranean precipitation pattern. The island experiences a rain shadow effect caused by its mountains. The western side is rainy and wild. It is home to the Valdivian temperate rain forests. These are one of the few temperate rain forests in the world. The eastern shore is warmer and drier because the mountains block much of the moisture. The island runs from 41º47'S to 43º26'S. This specific climate supports a wide variety of life.
Human history on the island began over 7,000 years ago. Early nomadic groups lived along the coast. They focused on hunting and fishing for marine creatures. They collected clams, mussels, and Choromytilus chorus. You can still find their remains in middens. A midden is an ancient dump for domestic waste. These sites contain mollusc shells, stone tools, and bonfire remains.
Spanish influence changed the island's culture and settlement. The explorer Alonso de Camargo first saw the coast in 1540. Captain Francisco de Ulloa reached the Chacao Channel in 1553. He is considered the first European discoverer of Chiloé. The Spanish claimed the archipelago later in the 1550s. The city of Castro was founded in 1567. Jesuit missionaries arrived at the turn of the 17th century. They built many chapels to evangelize the local population. By 1767, there were 79 such chapels. Today, more than 150 traditional wooden churches exist on the islands. Many are UNESCO World Heritage Sites. 
Economic shifts shaped the towns of the island. In the 1800s, Chiloé was a center for French whalers. From the mid-19th century to the early 20th century, it produced railroad ties. This industry led to the growth of towns like Quellón, Dalcahue, and Chonchi. In 1843, many Chilotes migrated to Patagonia for work. They often moved to Punta Arenas. Inland areas were occupied as farming rose in the late 1800s. A railroad between Ancud and Castro was built in 1912. This railroad is no longer in service. The capital city is Castro, located on the east side. Ancud is the second largest town. 
The marine environment near Chiloé is incredibly diverse. The northwestern area near Chiloé National Park is home to many species. You can find blue whales and sei whales there. Chilean dolphins and Peale's dolphins also live in these waters. Sea lions, marine otters, and penguins are common. The Islotes de Puñihuil Natural Monument is very special. It is the only known shared breeding site for Humboldt and Magellanic penguins. Other species like the red-legged cormorant and kelp gull breed there too. The Alfaguara project works at Puñihuil to research and conserve these animals. This research helps protect the local communities and the sea.
