I embarked on a boat trip to an island in front of the Marseille harbor in the morning. Ile d'If is a small but historically significant island primarily known for its fortress, the Château d'If. This 16th-century fortress gained fame through Alexandre Dumas' novel "The Count of Monte Cristo." Visitors can explore the well-preserved prison cells, courtyard, and enjoy panoramic views of the surrounding sea and Marseille's coastline. The island's history and its literary connections make it an intriguing destination for tourists interested in historical landmarks and the adventures of classic literature.
