If you travelling here by bus from Nice, take the no. 400 bus which will drop you off just outside the village.

Do not (as I did) take bus no. 94 which has a stop called “Les 4 chemins/Saint-Paul-de-Vence”. It doesn’t appear to be anywhere near the village, plus when I tried to get off there, the driver ignored me pinging the bell and merrily sailed past. In the end I carried on to Vence, and took the no. 400 bus to St. Paul de Vence from there.
