Catch the Circumvesuviana train from Napoli Centrale/Garibaldi toward Sorrento and get off at Ercolano Scavi — fastest, cheapest rail link for Vesuvius transfers. Trains run frequently; check live timetables on the day.
Buy a Vesuvio Express minibus ticket at/near the Ercolano Scavi station and board the shuttle that climbs toward the Vesuvius trailhead; reserve in advance in high season if possible.
Walk the marked trail from the shuttle drop-off up to the crater rim; the National Park path offers dramatic views of the Bay of Naples and the cone. Park trails normally open around 9:00 and close late afternoon — check the official Vesuvio National Park site for exact close/last-access times.
Spend a short time at the rim to photograph the crater and coastline, then descend at a steady pace to the shuttle pickup for the return to Ercolano. Allow extra time for steep sections and photos.
Return to Ercolano Scavi by the minibus shuttle and board the Circumvesuviana toward Sorrento or Poggiomarino, getting off at Pompei Scavi - Villa dei Misteri to access the main archaeological entrance.
Enjoy a relaxed lunch close to the Pompei Scavi entrance — Ristorante President is a reliable option for local pasta, pizza and seafood and is open for lunch (typically 12:00–15:00). Booking a table helps in high season.
Use the Pompei Scavi - Villa dei Misteri entrance and explore the remarkably preserved Roman streets, houses, frescoes and the Forum. The park normally opens 9:00–19:30 in summer (last entry rules vary), so pre-book your ticket to guarantee entry and skip queues.
After exiting or before heading back to the station, grab a quick espresso and a light snack from a café on Via Roma or near Piazza Bartolo Longo; use this time to buy any souvenirs or rest your feet.
Allow a comfortable buffer to walk from the archaeological area back to Pompei Scavi station, buy a Circumvesuviana ticket (machines or ticket office) and be on the platform for the 17:00 departure to Naples.
Board the Circumvesuviana train that departs Pompei Scavi at 17:00 heading back to Napoli Centrale/Garibaldi — expect roughly a 30–40 minute ride arriving back in Naples around 17:30–17:45 depending on stopping pattern.
