At 5,000 meters, this is not a casual walk in the park. You will feel the altitude immediately, so prioritize the guided Climate Change route to understand why the ice is actually disappearing. Spend no more than three hours here; it’s a high-impact, low-oxygen environment. Skip the horse rentals if you can handle a steep, 30-minute hike. Bring legit gear because the Andean weather shifts in seconds. It’s haunting, bleak, and totally worth the lung burn.
