Ajaccio is easily walkable, and most major tourist sites are located in the city center. However, if you want to explore more remote areas or attractions outside the city, a rental car or a guided tour can be a good idea. Taxis are also available, but they can be expensive. Transportation costs are not included in the estimated costs above.
If you have more time, consider visiting the birthplace of Napoleon Bonaparte or taking a boat tour to the Sanguinaires Islands. If you have less time, skip the market and head straight to the beach. Make sure to wear comfortable shoes and stay hydrated, especially during the summer months.
