The Fort Ives is worth a visit, and the speedboat from Marseille is very fast, and the return boat is very punctual. The whole castle is legendary because of the depiction of Dumas. This is clearly oriented in the experience of the visit. In addition to introducing the general situation of military and political culture, the castle also marked the cells held by the characters in the novel. At the same time, there are introductions to the surrounding ecology and island history on the island. In the off-season, there are very few people, and the general horse-watching will soon be finished. This kind of place really needs to be prepared in advance to find the fun, otherwise it will become a tour.
