One of the most important actions for the protection and the promotion of the natural wealth of Gyaros is the designation of underwater trails. The trails are specifically designed underwater paths that will have informative signs with information about the species, the biodiversity and the marine environment of the area. Everybody can enjoy these trails so long as they have the appropriate snorkelling gear. The only condition for someone to enjoy these trails is not to touch anything and to respect the particularities of the marine world.
