Corsica is a beautiful island and an excellent choice for a climbing road trip. Taking the night ferry from Toulon to Ajaccio effectively means it’s no further to drive to than the south of France and you wake up in the heart of the island. Amazing granite climbing in Bavella and the Restonica (camping Tuani) amongst others, great coastline, swimming holes, canyoning etc.
The problem is that many of the campsites shut at the end of September so the choice of places to stay becomes more limited the later you want to stay. Wild camping is not really tolerated so that’s not really an option. September is the sweet spot if you can make that work, once the summer crowds have left and before the island starts to shut down for the season
