We took the train from villefranche to Cagnes- sur-Mer (easy and cheap) but it was Sunday so no taxis available at Cagnes-sur-Mer. There was a phone number to a taxi company, but phonecard required for public phone and shop was closed - so not able to buy one. Limited bus service just along the road, but bus sailed past full. We finished up waiting 30 minutes for a train back to Villefranche
