Water along the way
Two liters per person per day is a minimum. You should take every oportunities you have to refill you bottles. All spring and fountain water is safe to drink. In the countryside, a spring often takes the form of a pipe protruding from a rock, or a leaf is placed in the spring to ease filling. Sometimes, the water is slow running and it takes a little time to fill up but it is worth being patient. You should keep avoid drinking from torrents, streams or rivers as they could be contaminated with animal waste or dead animals themselves. If you need to drink any, boil or clean it first with purification tablets.

Eating on the GR20

Most of the weight in you will have to carry will be food supplies. If you plan to carry your food, you should have at least two to three days worth of supplies. During the high touristic season (July/August), most refuges stock on basic provisions. But you can’t count on them for June, September or October.
Of course the food is sold at an inflated price (the wardens often have to hoist up the supplies by mules). But you will also buy yourself the luxury of not carrying so much supplies.

At Haut Asco, Col de Verghio and Vizzavona, you will find shops and bars selling supplies for hikers. Dehydrated and dried food are the best options: pasta, rice, bulgur, bread, beans, cereals, nuts or dried fruits. You can also purchase the delicious local “charcuterie”, you can choose from a wide selection: prisutu (smoked ham), coppa (shoulder), lonzu (smoked fillet), figatellu (long liverfilled sausages)...
