My suggestion is to start in St. Jean. With 4 weeks you should be able to get to Astorga or Ponferrada, both of which have good transportion options, bus or train. Start in May, June or Sept. Be prepared for wet, warm and cold weather any of those months. I'd carry both CSJ guide and the Brierley guide. -- Ralph Alcorn http://www.backpack45.com/camino2.html
