I am planning to go on the Camino de Santiago this spring for a month (April through May). This is the first time that I will make the Camino. English is my second language, but I can communicate in English. But I do not know anything about Spanish. Will I be OK without knowing Spanish on the Camino? I also want to make my backpack as light as possible (as everyone wants, I think). I am a mountain hiker, so I basically know how to make a backpack, but walking on the Camino may be different. Do I need to bring sleeping pad? Do all bunk beds in shelters have mattress? What guide book is good in information and light in weight? Can anyone give me some good thoughts? Thanks!
