This entire adventure is at high altitude. You will sleep at 3930 meters (12,894 feet) in the first night and trek to 4950 meters (16,240 feet) on Day 2. We recommend acclimatizing in Bogota (2640 meters / 8660 feet) for at least 2 days prior to this trip to avoid altitude sickness.
The physical demand of this trip is very high, with Days 2 to 5 each involving 6 to 10 hours of high altitude trekking on moderately hilly to steep terrain. You need to be very physically fit to go on this adventure.
You will need to carry a backpack with trail water, trail food, sleeping bag and your personal belongings (clothes, personal medicine, etc.)
Weather conditions do not always allow for reaching Nevado de Santa Isabel's high point. Your guide will determine whether it is safe to make an attempt.
