Whether you seek glacial valleys, ancient forests, or dramatic peaks, these off-the-beaten-path trails will take you deep into Patagonia’s untouched wilderness.

Why It’s Hidden
Cerro Castillo remains off the radar because it lacks the extensive infrastructure of Torres del Paine. Hikers need to be self-sufficient and carry all their gear, making it a true wilderness adventure.
