A sea cave below the San Pietro promontory in Portovenere, renamed for Lord Byron, who is said to have swum across the Gulf of Poets from here to visit the Shelleys in Lerici
Byron's Grotto, properly the Grotta Arpaia, is a sea cave set into the rocks below the San Pietro promontory at the tip of Portovenere, at the western edge of the Gulf of La Spezia, the bay long known as the Gulf of Poets. It takes its romantic name from the English poet Lord Byron, who stayed in the area in 1822 and, according to local tradition, swam from this spot across the gulf to Lerici to visit his fellow poet Percy Bysshe Shelley and his wife Mary, author of Frankenstein. A plaque near the Church of San Pietro records the feat and the literary associations that gave the gulf its name. The grotto itself has partly collapsed over the years, so it can no longer be entered as it once was; instead visitors view it from the terrace and rocks beside the church above, looking down into the deep blue-green water where it meets the cliff. The spot is reached by walking out through Portovenere to the San Pietro promontory, a short stroll from the harbour. A visit takes around twenty to thirty minutes as part of a wider exploration of Portovenere. The dramatic cliffs, the striped church above and the open gulf make the setting one of the most evocative on this stretch of eastern Liguria, especially in the golden light of late afternoon, when it pairs naturally with a visit to the church and a Portovenere boat trip.

Is it worth it for kids?
It is a brief, scenic and literary stop rather than an activity, but children enjoy the dramatic cliffs and the swimming legend; supervise them near the rocks.
