Ischia is a volcanic island at the northern end of the Gulf of Naples, about 30 kilometres from the city of Naples and the largest of the Phlegraean Islands. Roughly 10 kilometres across, it rises to Monte Epomeo at 788 metres and is shared by six towns with some 60,000 residents in all.
People have come here for the hot springs since antiquity, and Ischia remains above all a thermal island, with warm water flowing in spas, gardens and even into the sea. It also has sandy beaches, pine woods, vineyards on volcanic soil and a castle on its own islet, and it was the site of an early Greek trading post. Often called the green island, Ischia lends itself to longer, slower stays than a day trip allows. Holiday apartments and villas suit families and spa-goers, especially outside the July and August peak.
Ischia Porto, in the main municipality on the north-east coast, is the most convenient base: most ferries arrive here, and the town has shops, restaurants and a busy evening walk along Corso Vittoria Colonna. Ischia Ponte, a short distance east, is the older fishing quarter facing the Aragonese Castle and has a calmer feel. Casamicciola Terme and Lacco Ameno, on the north coast, grew up around thermal springs; Lacco Ameno has a small harbour and the Villa Arbusto museum.
Forio, the largest municipality by area, spreads along the west coast with beaches, vineyards behind and the gardens of La Mortella; its hamlet of Panza leads to Citara beach and the hot springs of Sorgeto bay. On the south coast lies the fishing village of Sant'Angelo, in the municipality of Serrara Fontana, and Barano d'Ischia leads down to the long Maronti beach. Homes on the hillsides often have views and gardens but need a car or scooter.
Ischia's volcanic heat feeds a great many springs, and their use goes back to the Greeks and Romans: votive tablets found at the Nitrodi spring in Barano were dedicated to Apollo and the nymphs who guarded the water. Today the island's thermal tradition takes many forms, from hotel spas and large thermal parks with pools at different temperatures to simple public springs.
The most famous free experience is the bay of Sorgeto, below Panza, where hot water rises among the rocks and mixes with the sea, so that people bathe here even in winter. Thermal water is mineral-rich and can be very hot at the source, so test the temperature before stepping in and limit long soaks if you have heart or blood-pressure concerns. Many visitors combine thermal bathing with mud treatments and massages offered in licensed spa facilities.
Ischia has several sandy beaches. Maronti, on the south coast below Barano, is a long stretch of sand, and Citara near Forio faces the west. Smaller beaches and coves lie around Sant'Angelo, Lacco Ameno and Ischia Ponte, and boat trips around the island reach bays that are hard to get to by road.
Inland, Monte Epomeo is not a volcano itself but a block of green volcanic tuff pushed upward by pressure from below; paths climb it past vineyards for wide views over the gulf. The island's last eruption, in 1302, produced the Arso lava flow on the north-east coast, now partly covered by pine woods. The surrounding waters are a protected marine area with meadows of seagrass, and several species of dolphin and whale are studied offshore.
Euboean Greeks founded a trading settlement called Pithekoussai on the island in the 8th century BC, where Greeks, Etruscans and Phoenicians lived side by side. A clay cup found in a grave here in the 1950s, known as Nestor's Cup and dated to around 730 BC, is an important early example of writing in the Greek alphabet. Finds from Pithekoussai are shown at the archaeological museum of Villa Arbusto in Lacco Ameno.
The Aragonese Castle stands on a volcanic islet joined to Ischia Ponte by a causeway. A first fortress was built there in 474 BC by Hiero I of Syracuse, and in 1441 Alfonso V of Aragon replaced the wooden bridge with a stone one. Around 1700 some 2,000 families lived on the rock. In 1883 an earthquake devastated Casamicciola and Lacco Ameno, killing more than 2,300 people. Henrik Ibsen wrote part of Peer Gynt in Casamicciola, and the composer William Walton made his home and garden at La Mortella in Forio.
Ischia's best-known dish is coniglio all'ischitana, rabbit slowly cooked with tomatoes, garlic, white wine and herbs, a reminder that island cooking was once as much about the hills as the sea. Fish and seafood are everywhere too, from grilled sea bass to spaghetti with clams and fried calamari.
Vines grow on the island's volcanic soils, and the Ischia DOC covers both white and red wines; whites, made mainly from the local Forastera and Biancolella grapes, account for most of the production. Small producers also distil liqueurs from island citrus, figs and herbs. Renting a home with a kitchen makes it easy to cook with the produce sold in village shops and markets, and to eat on a terrace in the evening, as many islanders do.
The nearest airport is Naples International Airport (NAP). Ferries and hydrofoils link the island's three ports, Ischia, Casamicciola Terme and Forio, with Naples and Pozzuoli. In Naples, hydrofoils leave from Molo Beverello and car ferries from Calata Porta di Massa, while Pozzuoli has car ferries only. Crossings take roughly an hour by hydrofoil and an hour and a half by ferry, depending on the route.
On the island, public buses run by EAV circle the coast road and connect all six towns. Taxis, scooters and small rental cars are widely available, and some visitors bring their own car on the ferry; check current rules first, as access for non-resident vehicles can be restricted in high season. Sant'Angelo and some beaches are easier on foot or by water taxi, and island traffic can be slow in summer.
Ischia has a mild Mediterranean climate, helped by its position in the central Tyrrhenian Sea and the mass of Monte Epomeo, which shelters parts of the coast. Winters are mild but changeable, with rain mostly brought by south-westerly and south-easterly winds, while northerly breezes prevail in spring and summer.
July and August are the busiest months, when the island's population swells with visitors and beaches and ferries are crowded. May, June and September are warm enough for the sea and pleasant for walking up Epomeo. Because thermal bathing is enjoyable in cooler weather, spring and autumn are especially popular with spa-goers, and some springs, including Sorgeto, can be used all year. In winter many hotels close, but the island stays lived-in and quiet. After heavy rain, follow local advice on landslide-prone slopes.
Ischia Porto is the most practical base, with ferries, shops and buses. Ischia Ponte is quieter, beside the castle. Forio suits beach lovers and sunsets over the west coast, Lacco Ameno and Casamicciola suit thermal stays, and Sant'Angelo suits travellers looking for a small fishing village.
From Naples International Airport (NAP), travel into the city and take a hydrofoil from Molo Beverello or a car ferry from Calata Porta di Massa. Ferries also leave from Pozzuoli. Crossings take about an hour by hydrofoil and about an hour and a half by ferry.
Ischia is known for its thermal springs, used since Greek and Roman times, for beaches such as Maronti and Citara, for the Aragonese Castle on its islet and for Monte Epomeo. It is also known as the site of Pithekoussai, a Greek trading post of the 8th century BC.
May, June and September offer warm sea and fewer crowds than July and August. Spring and autumn are popular for thermal bathing and hiking on Monte Epomeo. In winter the island is quiet and many hotels close, though some springs, such as Sorgeto bay, can be enjoyed all year.
Not necessarily. EAV buses connect all six towns, and taxis and scooters are easy to find. A car helps if you rent a hillside villa, but roads are narrow and busy in summer, and rules for bringing non-resident cars in high season should be checked before travelling.
Three or four days allow for the castle, a beach day, a thermal spring and a boat trip around the island. A week lets you settle into a rented home, walk up Monte Epomeo, visit Procida and enjoy the island at a slower pace.
Yes. Holiday rentals in Italy must have a national identification code, the CIN, issued through the Ministry of Tourism's accommodation database. The code has to appear in every online listing and be displayed outside the building, so you can check it before booking.
Yes. Sandy beaches such as Maronti and Citara, boat trips and the Aragonese Castle appeal to children, and distances on the island are short. Thermal pools are popular with families, but very hot water is not suitable for young children, so check temperatures and age guidance.
