Walking holidays & trekking at altitude - what to expect
Our walking holidays and trekking holidays are designed to allow gradual height gain, spread over a number of days. There is no way of predicting who will suffer from altitude but, for the vast majority of people, a slow ascent to height will produce minimal effects. On a few high altitude treks we carry a Gamow Bag as a precautionary measure.
The dossier pack that we send to you when you book your holiday includes comprehensive advice on safe travel at altitude. If you would like to find out more about the effects of altitude and the best preventative measures, then please visit the website of the research charity Medex and download their excellent booklet called 'Travel at High Altitude'. For treks involving travel above 4,000m/13,120ft, we'd strongly recommend that you read this booklet before you travel. You can also call our office and speak to an experienced member of our team.
