Capri and Ischia are the two most visited islands in the Bay of Naples — and they are almost opposites in character. Capri is compact, glamorous, and built almost entirely around a single spectacular experience: arriving by boat, climbing the funicular, and confronting a hilltop village that the Romans, the Victorians, and the celebrity world have all claimed as their own. Ischia is larger, greener, and centred on volcanic geology that produces both thermal springs and dramatic hillside towns — a working island that draws visitors for its spas, beaches, and relative affordability rather than its fame.

Choose Capri if you want the Blue Grotto, iconic clifftop scenery, and one of Italy’s most famous hilltop towns — and can absorb the prices. Choose Ischia if you want thermal spas, sandy beaches, a larger island to explore, and better value for a multi-night stay.
Scenery and Atmosphere
Capri’s scenery is extraordinary. The Faraglioni — three sea stacks rising up to 109 metres from the water off the island’s south coast — are among Italy’s most photographed natural features. The Piazzetta in Capri town is a masterclass in Mediterranean theatre: white-washed buildings, bougainvillea, designer boutiques, and a view down to the sea from every angle. The Villa San Michele at Anacapri (entry €10) sits on a promontory above a sheer cliff drop with views across the Bay of Naples to Vesuvius. This is beauty as spectacle — highly concentrated, instantly legible.
Ischia’s scenery is more varied and less immediately dramatic but rewards sustained exploration. The island is volcanic, which means forested hillsides, hot springs seeping into the sea, and a topography that changes entirely between the castle-dominated east coast, the thermal resort towns of Forio and Casamicciola, the fishing village of Sant’Angelo in the south, and the summit of Monte Epomeo (788 metres) at the centre. Sant’Angelo — a traffic-free village of pastel buildings clustered around a small harbour — rivals any village in the Bay of Naples for charm.
Winner: Capri for concentrated visual drama. Ischia for variety and sustained exploration.
The Blue Grotto — Capri’s Defining Attraction
The Blue Grotto (Grotta Azzurra) is a sea cave on Capri’s northwest coast where sunlight enters through an underwater aperture and reflects from the white sandy seabed, turning the water an intense electric blue. The effect is genuinely extraordinary — photographs suggest it, but the actual colour is more vivid than any reproduction. Entry costs €18.50, plus a rowing boat from the dock (approximately €18 per person) — total around €36–40 per person for roughly 30 minutes round-trip. The cave itself takes 5–10 minutes.
The caveats: the grotto closes in rough sea conditions (roughly 30–40% of days in winter), the queues in July and August mean waiting 1–2 hours for a boat, and the experience is brief. Visit in May or September for manageable queues and reliable conditions. Early morning (boats launch from 9am) has shorter queues and better light.
Ischia has nothing comparable in terms of a single spectacle — but the Grotta del Mago near Forio is a pleasant alternative for snorkellers.
Winner: Capri, unambiguously. The Blue Grotto is one of Italy’s great natural wonders.
Beaches
Capri’s coast is largely cliff and rock — there are no proper sandy beaches. The Marina Piccola on the south coast has a small pebbly beach (sunbeds from €20) that is pleasant for swimming in clear water, but the approach is down a steep path and the beach itself is compact. The Faraglioni bathing spots (accessible by boat or a long hike) are more private but still rock-based. Capri is not a beach island in the traditional sense.
Ischia has proper beaches. Spiaggia dei Maronti, on the south coast near Sant’Angelo, is a long stretch of dark volcanic sand with thermal water seeping up through the beach — warm to the touch even in autumn. Spiaggia di Citara on the west coast, near the Poseidon Gardens, is another long sandy beach with good facilities. Lacco Ameno in the north has a quieter sandy stretch. Overall, Ischia has more and better beaches than anywhere else in the Bay of Naples.
Winner: Ischia, easily. Capri’s appeal is not its beaches.
Thermal Spas — Ischia’s Ace
Ischia’s volcanic geology produces thermal springs throughout the island, and several large thermal parks have been built around them. The Giardini Poseidon at Citara (entry €32–40 depending on season) has 22 pools of varying temperatures (28–40°C), a private beach, water slides, and good restaurant facilities — an entire day’s activity. The Castiglione Terme spa at Casamicciola (entry €25–30) is smaller and more traditional. Many hotels have their own thermal pools included in room rates.
The thermal bathing is a genuinely therapeutic experience — the mineral content of the waters is high enough that extended bathing produces noticeable effects on skin and joints. It is one of the primary reasons Italians from Naples and Rome choose Ischia for breaks rather than Capri.
Capri has no thermal spa facilities.
Winner: Ischia, with nothing to compare on Capri.
Activities and Sightseeing
On Capri, the core itinerary is: the Blue Grotto, Capri town and the Piazzetta, the chairlift from Anacapri to Monte Solaro (€14 one way, €16 return, 12 minutes, panoramic views across the bay), the Villa Jovis — Augustus and Tiberius’s imperial palace (€8), the walk along the Via Krupp (a spectacular switchback path cut into the cliff), and the Giardino di Augusto (€1), which gives the best view of the Faraglioni. The Certosa di San Giacomo (a 14th-century Carthusian monastery, free) is often missed by day-trippers but outstanding. A full day covers this programme comfortably.
On Ischia, the Aragonese Castle (Castello Aragonese, entry €14) occupies a volcanic rock connected to the island by a bridge at Ischia Ponte — a complete medieval town in miniature with a cathedral, a convent, and remarkable views. Monte Epomeo (788 metres) is reachable on foot from Fontana (approximately 2 hours each way) or by donkey (from €15). The Giardini La Mortella at Forio (entry €18) are among Italy’s finest botanical gardens, created by the composer William Walton and his wife in the 1950s. Ischia gets better the longer you stay.
Winner: A draw on quality. Capri for a single-day programme, Ischia for multi-day depth.
Cost and Accommodation
Capri is one of Italy’s most expensive islands. Hotels in Capri town and Anacapri run €200–500/night for mid-range properties in summer; the Grand Hotel Quisisana (from €700) and Villa Treville (from €1,500) are the prestige benchmarks. Budget accommodation is extremely limited — a basic room in Anacapri starts at €120–180 in July. Restaurant prices are high: €20–35 for pasta, €40–60 for a main course with sea views. Day-trippers who arrive by hydrofoil and bring a packed lunch make the only genuinely affordable visit.
Ischia has accommodation at all price points. 3-star hotels in Ischia Porto, Forio, and Casamicciola run €90–180/night in peak season. Thermal resort hotels (which include spa facilities in room rates) cost €150–300/night. Small B&Bs and apartments in Sant’Angelo or Lacco Ameno run €80–140. Restaurant prices are similar to Naples: pasta from €12–16, fish mains from €18–28.
Winner: Ischia for value across all budget levels.
Transport and Access
Both islands are reached from Naples Molo Beverello:
- To Capri: Hydrofoil (50 minutes, from €27); slower car ferry (80 minutes, from €15 foot passenger). Services run from early morning to late evening.
- To Ischia: Hydrofoil to Ischia Porto (75 minutes, from €27); car ferry (90 minutes, from €18). Services also run from Pozzuoli, which is cheaper and less crowded.
Both are also reachable from Sorrento:
- Capri: 25 minutes by hydrofoil (from €18) — the most scenic approach, and the most popular
- Ischia: 65 minutes (from €20) — less commonly used but practical if you are already on the Amalfi Coast
Neither island requires a car. Capri bans private vehicles entirely. Ischia’s bus network connects all towns (€1.50/journey, or €6.50 for a day pass). Scooter hire on Ischia from €30/day.
Winner: Capri for proximity from Sorrento. A draw from Naples.
Day Trip vs Staying
Capri is Italy’s ideal day trip. The island is small enough (10 square kilometres) to cover its highlights in a full day. The first hydrofoil from Sorrento leaves at approximately 7:30am, and arriving early — before the main day-tripper wave at 10am — means a calm hour in the Piazzetta and a shorter queue for the Blue Grotto boat. Return by 6pm, when the island briefly empties and becomes peaceful. Staying overnight is worth doing once, but one night is sufficient.
Ischia does not work as a day trip. The thermal parks alone warrant a full day, and the island is large enough (46 square kilometres) that covering the Aragonese Castle, Sant’Angelo, and Monte Epomeo requires separate days. Most visitors who come to Ischia stay two to four nights.
Winner: Capri for day-trip ease. Ischia for stays of two nights or more.
Final Verdict
Capri wins for concentrated beauty, the Blue Grotto, and the experience of one of Italy’s most iconic settings — if the budget allows. Ischia wins for thermal spas, proper beaches, better value, and the depth that rewards a longer stay.
The ideal Bay of Naples trip does both: a day trip to Capri for the Blue Grotto and the Piazzetta, then two or three nights on Ischia for the spas, the castle, and the village of Sant’Angelo. From either island, Naples is under 90 minutes away and easily combined.
