East towards the Italian border, the white limestone Pre-Alps fall almost directly into the sea, creating some of the French Riviera’s most dramatic settings and exclusive peninsulas. The Grande Corniche road goes all the way to Menton via Roquebrune. You can stop off at La Turbie or explore inland villages such as Peillon and Peille. La Turbie’s star attraction is the Trophée des Alpes, a ruin standing guard over Monaco.
