I seem to recall this topic in Tripadvisor, but can't find it.
I believe someone (Nicelife?) was saying that it is perfectly feasible to walk from Nice (we are currently in Vielle Ville for a week) to Villa Ephrussi de Rothschild in Cap Ferrat.
Is there a pedestrian friendly way to get there? If so how long might it take, and what would be the directions?
