Talk to your doctor about which is best for you given your medical history and trip plans. Medicines are available to prevent acute mountain sickness and shorten the time it takes to get used to high elevations.

Consider taking day trips to a higher elevation and then returning to a lower elevation to sleep.Traveling to elevations greater than 9,000 ft for 2 nights or more, within 30 days before your trip, can help avoid altitude illness on a longer trip at a high elevation.Do not drink alcohol or do heavy exercise for at least the first 48 hours after you arrive at an elevation above 8,000 feet.For every 3,300 feet you ascend, try to spend an extra day at that elevation without ascending further. Once you are above an elevation of 9,000 feet, increase where you will sleep by no more than 1,600 feet per day.This gives your body time to adjust to the lower oxygen levels. If possible, spend a few days at 8,000–9,000 feet before traveling to a higher elevation. Avoid traveling from a low elevation to an elevation higher than 9,000 feet (2,750 m) above sea level in one day. Below are tips you can follow to prevent altitude illness. If you plan to travel to an elevation higher than 8,000 feet above sea level or higher, you may be at risk for altitude illness, which is caused by low oxygen levels in the air.
