Knowing what to pack for a challenge like this, if you haven't done something similar before, can be daunting!
We've broken down the essentials below for you, and provided a link to a downloadable sheet at the end -
Two or three T-shirts plus one with long sleeves (to protect against sun/chill).
Shorts and trousers. A good solution are zip-off pants with removable leggings.
A light sweater/summer fleece for cooler nights (or days).
Raincoat/poncho with cape. It should cover your backpack, too.
A pair of hiking shoes. Preferably Gore-Tex or the like. These shoes are water resistant, yet let your feet breathe. As soon as you try them on in the shop, there should be no doubt that they are comfortable. Don't make any compromise here. Also keep in mind that feet have a tendency to swell in warm weather.
A hat or bandana to protect you from the sun.
Three pairs of hiking socks. Quality is very important here to avoid the biggest fear of every pilgrim: blisters.
Walking poles (optional). They are useful on downhill and uphill paths, and also in wet and muddy conditions, but will turn into extra weight when not needed.
A pair of sandals. They will serve you well when strolling around in towns.
A pair of plastic slippers or flip-flops.
Pyjamas (or just a pair of shorts and a T-shirt).
Shower gel. Preferably with protection cap on top.
Soap (washing soap also).
Toothbrush and a small quantity of toothpaste.
Face cream and/or suntan lotion.
Something against flu for the first few days. Some people experience the syndromes of influenza after the first few days.
Any medicine you usually take.
Sticking plasters that you can cut yourself.
Tea tree oil to disinfect wounds and blisters.
Wound treatment creme, also good for wounds caused by sweating.
Comfrey creme for treating arthritis, inflammations or bruises.
Some sports cream to treat your feet with after a day's walk (and also to massage other hurting body parts).
A pocket knife.
A pair of small scissors.
Something to read if you're the reading type; something to write on and with if you're the writing type.
Headlamp or small torch.
A small sewing set.
Some safety pins.
A smaller shoulder bag or neck wallet for your documents.
