My friend and I plan to tour northwest Spain, Pyrenees heading to Santiago de Compostela, from Provence and the Toulouse area. What are the various train connections? Bus routes? To see attractive smaller towns will it be necessary to rent a car? All postings I see are from/to Barcelona and the Riviera. Help!
