Admire the cathedral’s mix of Norman, Moorish and Baroque styles and, if open, climb to the rooftop for city views (generally open mornings; check local hours).
Join a guided tour (cable car/jeep or walk options) exploring craters and recent lava flows — organised tours generally run midday and afternoons; book in advance.
Spend the afternoon at this picturesque pebble beach and marine reserve — ideal for swimming and scenic downtime (access may be restricted at high tide).
Explore the remarkably preserved Roman city buried in AD 79, including homes, theatres and baths; arrive early where possible since site opens in the morning (check seasonal hours).
Walk the moderate trail (~45 mins ascent) to the crater rim for panoramic views of the bay and Naples; late-afternoon visits offer softer light but check park closing times.
Visit one of the world’s premier collections of Greco-Roman artifacts, including finds from Pompeii and Herculaneum (typically opens mid-morning; check opening times).
