Sightseeing Tours in Naples vary in duration to cater to different interests and schedules. Most walking tours last between 2 to 3 hours, while in-depth explorations, such as the Herculaneum In-App Audio Tour, might take a half-day to fully appreciate the site. For a comprehensive experience of the city, some visitors may prefer full-day tours. However, self-guided audio tours offer the flexibility to enjoy at one's own pace, possibly extending across a full day or broken up into shorter segments over multiple days.
