Dates are flexible. This day-by-day plan is provisional until you choose exact travel dates.
Start at Piazza del Plebiscito, ideally around 9:00, when the vast square is still relatively calm. Take in the colonnade of Basilica di San Francesco di Paola, the Royal Palace of Naples, and the equestrian statues of the Bourbon kings; the square is especially atmospheric with Vesuvius-facing light in the background. Allow about 30 minutes, then cross directly to the Royal Palace of Naples for the State Apartments and grand ceremonial rooms. Plan roughly 1½ hours, including the security queue. Opening days and hours can change, so check the official listing shortly before visiting and reserve an admission time if offered; budget approximately €10–15.
Walk a few minutes to Gran Caffè Gambrinus on Piazza Trieste e Trento for an unhurried Neapolitan coffee and pastry—try an espresso with a sfogliatella or baba. The historic interiors are part of the appeal, though table service can cost more than standing at the bar; expect about €5–12 per person. Afterward, allow around 20 minutes to reach Galleria Borbonica in Chiaia, either on foot through the streets behind the waterfront or by taxi if you prefer to save energy. The underground Bourbon Tunnel is cool, uneven, and atmospheric, so wear sturdy shoes; tours run at limited times and advance booking is strongly recommended, with entry commonly around €10–15. Do not rely on simply arriving and finding space.
Head toward Santa Lucia for dinner at Trattoria Castel dell’Ovo, allowing 15–20 minutes by taxi or roughly 25–30 minutes on foot from the tunnel area. Verify the restaurant’s current opening hours and reservation policy before setting out; for a seafood-focused meal, allow 1½–2 hours and approximately €30–50 per person, depending on fish and wine. Finish with a relaxed walk along Lungomare Caracciolo toward Castel dell’Ovo. The castle’s exterior and the bay are particularly good after sunset, with views toward Vesuvius and the lights of the waterfront; allow about an hour, and use a taxi for the return if the seafront feels too quiet or you are heading farther inland.
