I did the primitivo last september and was very pleased! I am 74 and in reasonable shape and had no trouble. The talk about it being very difficult,is mostly hot air. I think a 12 year old will find it very interesting and not get bored. I would heartily recommend taking the camino verde to sobrado on the norte and then going directly to lavacola and santiago,completely avoiding the frances. I went this way to avoid the hoardes of people on the frances(my personal decision). It was well marked and easy to follow,in spite of what is said about it. I left oviedo on august 31,found the weather,SEATTLE-LIKE,it never got warmer than 65 f. It only rained 1 day,but was cool at night,being about 40-45 degrees at night. Take a sleeping bag!! I took a silk liner and found myself cold in the night. Only one alberque had blankets,and they were rentable. Saw only a few people with bed bugs,and did not seem to be a problem. Scenery was wonderful! I went the hospitalis route and found it a disappointment. If I do it again I would go the other way. The oohs and aahs on the h. must be from people who live in Kansas,as I found it nothing special. I hope that I have filled in some of the blanks. By the way,if you have time,walk on to Muxia,and see the ocean. This is a wonderful,easy 90 more kilos. More importantly,BUEN CAMINO!
