Bosque Piedra Reserve: Private Forest & Geology Expedition

Explore Chiloé's extraordinary 'Stone Forest' reserve — a surreal landscape of ancient volcanic rock formations erupting from dense native temperate rainforest. One of southern Chile's best-kept secrets, best experienced with an expert naturalist guide.

What to expect

The journey from Castro winds through farmland and into the cool, cathedral-like Valdivian rainforest, where lichen-draped coigüe trees tower over moss-carpeted trails. The reserve's signature rock pillars — shaped by millennia of volcanic activity and erosion — rise dramatically from the forest floor, creating natural viewpoints over the island's rolling green interior. Your naturalist guide explains the geology, points out Chiloé woodpeckers and austral parakeets in the canopy, and shares Huilliche plant lore at every turn. The pace is unhurried and deeply immersive.
