There are a number of options.
- Most albergues will provide either a re washable cotton or synthetic sheet or a disposable paper one to fit over the mattress. They both work well as the focus of the people responsible for providing the beds or bunks is on both hygiene and minimising bed bugs. Some people elect to take their own sheet to fit on top of the one supplied. It may be one treated to repel bed bugs.
- Many people, myself included, opt for a sleeping bag liner which can on warm evenings be used on its own without the need for a sleeping bag. When very cold I use it inside the sleeping bag. There are many different materials and designs. For my first Camino I was lent a Sea to Summit Silk Liner with the pillow insert. I have since bought my own and think it is wonderful (though pricey)
- Don’t take anything and rely on sheets etc being supplied.
NOTE. if you plan to stay in pensions or small hotels, gites and similar you will be paying a much higher nightly rate than in an albergue and can expect all bedding, including sheets and blankets, to be included in the cost. Sometimes meals are also available at a reasonable cost. Having said that many of these private, often family run, places on the Camino are far less expensive than ordinary hotels and hostels.
Caution. Just check on the weights of any sleeping sheet or sleeping bag liner. You don’t want to find you have inadvertently added 400-500 grams. My Sea to Summit silk liner is 179 grams.
I have provided some links where you can find out more.
