The trail
The trail is normally done in 15 days, however people often do it in less. It may be walked in either direction, and often in parts, with Vizzavona being an ideal place to start or stop.

Food can be purchased in most refuges, however they are stocked to varying degrees. In the south of the island below Vizzavona you can often get fresh bread, however you can often get "long life" bread otherwise. You can usually get various supplies such as cheese, saucisson, snack-bars and beer at refuges, with a greater variety at some of the villages and ski resorts en route. Most refuges will supply you an evening meal if you book in time.
There are marked water sources near all of the refuges, and are the occasional marked sources on route which are safe to drink. Springs dry up in the summer months and there are some long ridges without points of resupply, so it is wise to take out more than 2l of water.
 Fuel and cooking
Most huts have areas with stoves that you can use if you provide your own pans. These can get busy, or sometimes don't work, so if you want to cook your own food it may be a good idea to take a stove along. If you don't mind a few cold meals, not taking a stove will save weight.
 Camping and refuges
You can stay in most refuges if they're not full, however they can get quite busy. Some huts will provide rentable tents. Camping or as it is referred to "bivouacking" is allowed by refuges all along the route. You can book in and pay the hut guardian when you arrive.
Take as little as possible, pack light!
