Unexpected Weather Reality
Cotopaxi National Park, located in Ecuador's Andes at elevations exceeding 5,000 meters, defies typical tropical expectations with its high-altitude alpine climate.

"The volcano's height creates its own weather; expect the unexpected," warns park guide Luis Herrera, with 20 years experience.
Climate Change Impacts
Over the past decade, glacier retreat has accelerated 25%, shortening snow seasons by 18 days per year, per 2025 INAMHI reports. This extends dry windows but increases rockfall risks by 40% on melt-exposed routes.
Projections for 2026-2030 predict 15% wetter wet seasons, raising avalanche probabilities during El Niño years.
