Astroni Crater WWF Nature Reserve

The Astroni Crater Nature Reserve, managed as a WWF reserve, occupies an extinct volcanic crater in the Agnano area on the western edge of Naples in Campania, Italy. The entrance is on Via Agnano agli Astroni 468. The site was a royal hunting estate for centuries, and its crater walls sheltered beech, oak and chestnut woods that are unusual at this low altitude. Visits are by guided tour only, and booking is mandatory through crateredegliastroni.org. The reserve is open to visitors on Saturdays, Sundays and holidays, with summer hours of 10:00-18:00 and a last entry at about 15:40. To reach the entrance, visitors can take Metro Line 2 to Napoli Campi Flegrei or the Cumana railway to Agnano, then a taxi of roughly 10 minutes. Drivers can use the parking area near the gate. Guided routes cover about 4-6 km depending on the itinerary and take 2.5-3 hours. The elevation change between crater floor and rim is roughly 100-150 m on gentle, well-maintained paths, so the technical difficulty is low and the walk suits families and first-time hikers. Surfaces are mostly packed earth and gravel with some stepped sections, and the dense woodland gives much of the route shade. Along the way the guided path passes small crater lakes, old hunting-lodge structures and viewpoints where birdlife, and in places fallow deer and other wildlife, can be observed. The loop is led by the guide, who sets the turn-around points and pace. Drinking water is not guaranteed on the route, so visitors should bring their own, along with insect repellent in warmer months. There are no refuge huts, though sheltered buildings near the entrance serve as the base for tours. The reserve closes in rain, strong wind, weather alerts and during seismic swarms, so the booking confirmation and the reserve's website should be checked shortly before the visit.
