More ways to explore the area's outdoor wonders
The sun wakes the Ligurian Sea to a glassy blue as you step from Monterosso's stony beach and slip into water that feels colder at first touch, then utterly cleansing. Rocks and Posidonia meadows pass beneath you, and a guide points out a sudden flash of color—a wrasse weaving through a field of algae—while your mask magnifies the small, ordered world of the seabed.
