For a nice seaside promenade, look no further than the Via Caracciolo e Lungomare di Napoli. Flanked by cafes and restaurants on one side and the Gulf of Naples on the other, this walkway serves as a relaxing place to stretch your legs and breathe in the fresh sea air. The views of nearby Mount Vesuvius and the island of Capri add an almost magical element to this pedestrian walkway. 

Although recent visitors say a walk on Via Caracciolo e Lungomare di Napoli is a definite must-do, they recommend steering clear during the weekends when it gets "extremely crowded." Some also cautioned that vendors trying to hawk their goods can be a bit pushy, so be prepared to say a kind but firm "no, grazie" a time or two.

This promenade is free to walk 24 hours a day, but the shops, cafes and restaurants located alongside it will likely tempt you with their savory aromas – and those aren't free. Several buses make stops nearby. You'll find this pedestrian area winding 1.5 miles along Via Partenope and Via Francesco Caracciolo in Naples' Chiaia district.
