Yes, you read that right - many French people agree that Corsica is a great place for a holiday. Very varied landscape, beaches, hills, water, lots of outdoor activities - but you need a car.

Sea and harbour in Corsica
I had some French friends here recently who said that they enjoyed their holiday in Corsica so much last year that they are going back this year.
I also read in Le Point something similar that the French who go to Corsica once always go back - its a hidden gem.
Don’t believe me though have a look at these from a friend of mine Stephanie who comes from Corsica
