Tom Vermeersch + 6000m | AconcaguaRoeselare5/517-11-2023Excellent service. We cannot know what it would have been like without the preparation in the altitude tent but we both suffered quite a lot. Starting at 2,800 metres, 2 days later (at 3,400 metres) I had a splitting headache. Another 2 days later (at 4,800 metres) Tine was not in good shape (massive headache and vomiting). It took until day 8 - after also some acclimatisation trips above 5,000 metres - for us to be adjusted. The 6,200-metre summit was then no longer a problem.
