It was years before I discovered this most beautiful hidden gem just two miles north of Cannes. It takes a little effort to get there - but its worth it ten times over. Take a bus from Cannes centre to LeClerc Le Cannet (end of the line) and follow signs up for old Le Cannet.
The highlight is the magical Place Bellevue and the rue Le Sauveur. Four restaurants form an alfresco eating space with a view down over Cannes and the distant sea. The street is wonderful old classic French with artists workshops and artefacts. It is truly a gem
Best and most accessible jumping off point for St Tropez is the port of Cannes. From here you can be in glitz heaven in a little over an hour.
The Trans Cote d'Azur run in June to October - every day July to September, selected days outside this peak, and at 32 Euro round trip its not cheap, but its the only convenient way in and out of St Trop.
Boat goes out at 9.00 and leaves for the return at 4.30. It does not wait - as we witnessed on our last trip. Two ladies were a few minutes late and the boat sailed off, with them running alongside shouting "Yoohoo!" to no avail. Expensive situation!
