Understanding and Preventing Altitude Sickness on Chirripó

Cerro Chirripó reaches an elevation of 3,820 meters (12,533 feet), placing hikers at a considerable risk of Chirripó altitude sickness. Understanding its symptoms and prevention strategies is crucial for a safe ascent.

Acclimatization and Pacing

• Slow and Steady: Hike at a comfortable pace. Avoid rushing, even if you feel strong. Listen to your body and take frequent breaks.
• Hydration and Nutrition: Drink plenty of water or electrolyte-rich fluids. Dehydration can exacerbate altitude sickness symptoms. Eat a balanced diet with carbohydrates for energy. Avoid alcohol and caffeine before and during your ascent.

• Descend if Symptoms Worsen: If you or a companion experience altitude sickness symptoms that are getting worse, the safest course of action is to descend to a lower elevation immediately. Do not continue ascending.
