We are volunteering in Africa, and our easily changeable tickets are with Swiss Air through Zurich. We hope to end up with a week in July at Murren. Upon our arrival in Zurich end of May, we thought of traveling by train via Genoa (or Milan?) to Menton / Antibes on the Cote D'Azur or French Rivera. After two weeks in that area, we had thought of finding weekly rentals in southern France, as far north as Lyon. Can you suggest a "circle" to and from Zurich to accomplish this travel, either a "clock-wise" or "reverse clock-wise" path? Thanks very much.
