We can go on foot along the “Via dell’Amore” (the Love Road”) from Riomaggiore to Monterosso, otherwise we can sail close to the shore from Portovenere, passing between Palm aria and Tino.
If you want, there is the possibility of guided diving, accompanied by an experienced skin-diver and by marine biologists.
