Ineke Hallebeek + 5000m | KilimanjaroApeldoorn5/510-5-2017We flew from approximately 0 to 3600 meters. In Lhasa we could not run up the stairs, but had no complaints of headache or other symptoms of altitude sickness. My daughter only suffered from mild nausea for one afternoon at about 5000 meters. We had risen about 600 meters that day and had walked for about 2 hours to and from the Base camp of Mount Everest. We had a wonderful trip. Fortunately not been sick, those 2 weeks. Thanks for the service, the height tent really helped.
