I trained here for a month ahead of a 6,500m trek to get get a head start on the acclimatization process and work on overall fitness. Couldn't have been happier with the results. The trek went great and I didn't have any issues with altitude sickness, not even a slight headache. The staff here are all great - they take care of you and check in regularly to ensure you're feeling good and progressing well towards your training goal. Can't wait to come back ahead of my next trek in 2024!
