Ask the Expert Dave Musnick Dave Musnick text here . Previous Answers People can experience mild altitude sickness when going from near sea level to altitudes of around 8,000-9,000 feet. Symptoms are usually nausea and a headache. I would recommend that you not exert yourselves too much the first day if possible and drink plenty of fluids.
Most people are fine by the second day at altitude.
Most serious altitude problems do not start until 10,000 feet. All rights reserved. Privacy policy .
