Introduction — Why go snorkeling from Naples to Capri, Ischia and Procida
Setting out from Naples for a day (or several) of snorkeling trips to Capri, Ischia and Procida is a concentrated taste of the Mediterranean: weathered cliffs, hidden coves and crystal-clear waters teeming with marine life. From Naples’s historic port you can reach in under an hour islands that have inspired poets and painters: Capri with its limestone cliffs and deep blue waters, Ischia with thermal springs and lively reefs, and Procida with its picture-book bays and fish-rich seabeds. Together they make a perfect trio for snorkeling, swimming, enjoying local food and soaking up culture.
Snorkeling isn’t just a sport — it’s a slow, intimate way to meet the marine ecosystem. With a mask, snorkel and, if needed, a shorty wetsuit for cooler spring and autumn waters, you can watch schools of fish, colorful gorgonians, starfish and occasionally octopus sheltering under rocks from the surface. Trips from Naples cater to all levels: short outings by RIB for a few hours, full-day tours with multiple stops and lunch on board, or private charters focused on freediving and underwater photography.
From a practical standpoint Naples is well equipped: Porto di Napoli — Molo Beverello (Via Cristoforo Colombo, 80133 Napoli NA, Italy) is the main quay where hydrofoils and ferries depart; companies like SNAV, Alilauro and Caremar run frequent connections. Snorkeling boat trips leave either directly from Naples or from one of the islands after a crossing. Booking in advance in high season (June–September) is strongly recommended. This guide will walk you step by step: must-see swim-and-explore spots, exact departure points and landmarks to plan transfers, realistic price ranges in euros, indicative schedules, and lots of local tips to make the most of every stop.
We’ll break it down island by island: the best snorkeling spots (caves and drop-offs, Posidonia seagrass beds, rocky coves), excursion options (group, private, skipper-guide combos), where to rent or buy gear on site, and how to combine a day on the water with a typical lunch, a thermal dip or a cultural visit. Whether you’re in Naples for a weekend or a longer stay, these outings are an unforgettable sensory way to experience the Mediterranean — the light on the water, the clarity of the seabed, and the distant sound of ferries linking the islands.
Capri: best snorkeling spots, access, addresses and prices
Capri is the best-known of the three for dramatic geology, sea caves and the famous Faraglioni stacks. For snorkeling you’ll want different spots depending on how intense you want the swim to be: Marina Piccola, the waters around the base of the Faraglioni, Punta Tragara on the Marina Piccola side, and the Anacapri coast near Punta Carena. These areas offer rocky drop-offs, caverns and small pebble beaches that make getting in and out of the water straightforward.
Main arrival point / address: Marina Grande di Capri, Via Marina Grande, 80073 Capri NA, Italy. Most excursion boats and private charters leave from here. Snorkeling boat trips typically come as half-day (3–4 hours) or full-day (6–8 hours) tours with swim stops and lunch. Indicative prices: group half-day ≈ €50–70 per person; full day ≈ €90–140 per person. Mask/snorkel rental on site ≈ €10–20 per day; shorty wetsuit ≈ €10–25.
Must-see: Grotta Azzurra (Blue Grotto), access and details: Grotta Azzurra, Marina Grande, 80073 Capri NA, Italy. Entrance is by sea in small traditional rowboats (barche a remi). Typical opening hours: generally 09:00–17:00 (varies by season and sea conditions). Cost: there’s an additional boat ride fee handled by the rowboat operators and local administration; total cost can range around €14–18 per person for the boat trip plus an extra access fee in some cases (allow another €14–20). Note: the Blue Grotto is not a snorkeling site but remains an unmissable visual experience before or after your swims. Check sea conditions — the grotto is sometimes closed when the sea is rough.
Practical tips for Capri: aim for the early hours to avoid the busiest boats and to enjoy calmer water; bring water shoes for rocky stretches; protect your skin with water-resistant sunscreen and an anti-UV shirt; if you film underwater, use a waterproof housing or action camera to capture rock formations, schools of bogues and groupers. If you want to mix culture and snorkeling, climb up to the Piazzetta di Capri (Piazza Umberto I, 80073 Capri NA, Italy) for a panoramic coffee before catching the ferry.

Ischia: freediving spots, marine thermal springs and useful addresses
Ischia is known for nutrient-rich waters, Posidonia seagrass meadows and warm pockets where marine life thrives. The island mixes sandy and pebble beaches with volcanic coasts where thermal springs flow into the sea. Top snorkeling zones include Baia di Citara (Forio d’Ischia), Spiaggia dei Maronti, the area around Castello Aragonese and the Sant’Anna marine reserve (southeast near Sant’Angelo).
Main arrival point: Porto di Ischia (Ischia Porto), Via L’Approdo, 80077 Ischia NA, Italy. From the port you can reach the best freediving sites by local boat or water taxi. The island’s landmark to visit after swimming: Castello Aragonese, Piazza d’Armi, 1, 80077 Ischia NA, Italy. Opening hours for Castello Aragonese: usually 09:00–19:00 in high season (check locally). Entrance fee: ≈ €6–10 depending on exhibitions.
Prices and excursions: Naples–Ischia hydrofoil ≈ €15–25 one way depending on company and season. Guided snorkeling trips from Ischia for a half-day ≈ €45–80; full day with lunch ≈ €90–130. Gear rental: masks and snorkels ≈ €8–15 per day, wetsuits ≈ €12–30. For scuba divers, several centers offer try-dives and guided dives around the Secca di Santa Maria and volcanic drop-offs; try-dive rates ≈ €60–100 depending on depth and duration.
Recommended freediving sites in detail:
– Baia di Citara (Forio d’Ischia): clear water, typically lined with thermal hotels (reference address: Baia di Citara, 80075 Forio NA, Italy).
– Spiaggia dei Maronti (Barano d’Ischia): long volcanic beach with parking access from Via Maronti, 80070 Barano d’Ischia NA, Italy. Great for heading offshore to reefs;
– Castello Aragonese (Ischia Ponte): the cliffs beneath the castle shelter caves and small coves.
Local tips: currents can be strong near rocky points — always tell the captain or guide your level; waters here are often warmer than around Capri thanks to volcanic activity, but a shorty can still be useful in spring.

Procida: coves, Corricella, Vivara and practical addresses
Procida is the smallest and most authentic of the three islands. Less touristy than Capri, Procida offers scenic inlets and very green seafloors, ideal for snorkeling with often excellent visibility. Marina di Corricella is the classic postcard image: colorful houses, fishing skiffs and easy access to the water for solo or guided outings.
Main arrival point: Porto di Procida, Via Roma, 80079 Procida NA, Italy. The emblematic snorkeling and swimming neighborhood: Marina Corricella, 80079 Procida NA, Italy. For a post-dive stroll head to the Terra Murata promenade (Via Regina, 80079 Procida NA, Italy) for viewpoints over the bay. Vivara, the small islet connected by a narrow bridge, is a nature reserve (Riserva Naturale Isola di Vivara) — it’s mainly explored on foot, but the waters around Vivara are excellent for observing underwater life.
Prices and connections: Naples–Procida hydrofoil ≈ €12–18 one way. Day snorkeling trips from Procida or from Naples (including a Procida stop) ≈ €40–90 depending on number of stops and duration. Mask/snorkel rental on Procida ≈ €8–15. For underwater photographers, the small coves around Corricella and the northwest sector near Punta Pizzaco offer crystal-clear water and rockfish assemblages.
Practical tips for Procida: choose a small-boat outing (6–8 people) to reach narrow inlets; bring water and a snack since dining options are limited off-season. Corricella is perfect for a late seafood lunch — a typical address to eat facing the harbor: suggested: Ristorante La Lampara, Corricella, 80079 Procida NA (opening hours vary; fish dishes average €18–35). Cultural breath: visit the Abbey of San Michele (Terra Murata) for panoramic views of the archipelago.

Practical organization from Naples: ports, companies, timetables and detailed costs
Your snorkeling adventure usually starts at Porto di Napoli — Molo Beverello, Via Cristoforo Colombo, 80133 Napoli NA, Italy. Molo Beverello serves Capri and Procida by hydrofoil (aliscafo) and some connections to Ischia. For Ischia there are also slower, cheaper conventional ferries from Molo Beverello or from the porto di Pozzuoli (if you’re on the west side of the bay).
Companies and indicative fares (2024–2025 season, check at the time of travel):
– Hydrofoil Naples ↔ Capri (operators: SNAV, Alilauro): €20–30 one way. Duration: 40–55 minutes.
– Hydrofoil Naples ↔ Ischia (operators: SNAV, Caremar): €15–25 one way. Duration: 40–60 minutes.
– Hydrofoil Naples ↔ Procida: €12–18 one way. Duration: 40–50 minutes.
– Private snorkeling boat charters (departure Naples): typically €300–700 for a half-day (capacity 6–10 people); cost is often split among passengers.
Typical timetables: the first hydrofoils to Capri and Ischia depart between 07:00 and 08:30 depending on season; last returns range from 17:00 to 20:00. Snorkeling boat trips usually leave in the morning (08:30–09:30) and return early evening to enjoy the sunset. Rental shops and gear vendors typically open 08:30–19:00 in high season, closing earlier out of season.
Practical tips:
– Book ferry and excursion tickets online in advance during high season (July–August), or buy early at the Molo Beverello ticket counter.
– Bring ID and cash: some smaller guides accept only cash, especially for tips.
– Check marine weather: swell and wind can cancel snorkeling trips; if canceled always ask about refund or rescheduling policy.
– Prefer shoulder seasons (May–June and September) for clearer water, fewer crowds and gentler prices.
– If you’re into underwater photography, bring a large dry bag to protect your equipment during boat transfers.
Detailed local advice: safety, equipment, food and environmental respect
Safety and behavior at sea: always tell the captain or guide your swimming level and any medical conditions (allergies, asthma). Use a buoyancy aid if you’re not confident in the water — many trips provide them. Don’t dive headfirst into unfamiliar areas: rocky bottoms and Posidonia meadows can hide shallows. If you picnic or have lunch on board, minimise waste and never throw anything into the sea.
Gear and equipment: choose a good-quality mask with a tight seal and a snorkel with a purge valve to prevent water ingress. Shorty wetsuits are handy in spring and autumn; in summer the water can be warm but a suit helps against jellyfish stings and abrasions from rocks. Renting on site is convenient if you’re travelling light, but if you snorkel regularly bring your own mask for the best fit.
Local food to round off the day: after a morning in the water, lunch on the harbour is an essential pleasure. In Capri: Ristorante Da Paolino (Via Palazzo a Mare 11/15, 80076 Anacapri NA) is famous for its lemon grove atmosphere. In Ischia: Ristorante Il Mosaico (Via Tommaso Manzi, 80077 Ischia NA) for refined local cuisine (average meal €25–60). In Procida: Ristorante La Lampara, Corricella, 80079 Procida NA, Italy, offers fresh fish dishes (€15–35). Always try local specialties: spaghetti alle vongole, pesce arrosto and artisanal limoncello.
Respecting the environment: don’t touch marine animals, and don’t collect shells or rocks. Posidonia seagrass beds are protected habitats essential for water quality and fish reproduction — avoid entering these areas and never drop anchor on them; ask the captain to anchor on sandy patches. Use biodegradable sunscreens to reduce chemical pollution on reefs.
