Hygiene when trekking generally has improved considerably over the last ten years; I have local knowledge to choose the lodges, which maintain a high standard of hygiene. If you are camping in a tent, all meals are prepared to high standards, fruit and vegetables are soaked in iodine before preparation. Most lodges serve boiled and filtered water, which is generally safe, we suggest a drop of iodine to be totally sure. We discourage the purchase of bottled water for the obvious environmental reasons. Please bring a water bottle with you, which you can refill.
