“Be aware that your boat ride may be postponed due to rough seas or winds. We finally went on one after four days of cancellations.” A reader on the Rick Steves forum left that note about Capri last spring. It’s the most useful thing anyone says about the Blue Grotto online, and the rest of this guide tries to live up to it.
The boat trip is the reason most people come to Capri. The Blue Grotto, the Faraglioni, the swims off Marina Piccola. But the conditions decide what you actually see (the same wind-and-swell lottery that runs the Ajaccio coast trips out of Corsica and the Sainte-Marguerite ferry off Cannes), and the cheapest tour that “stops at the Blue Grotto” might not stop at all the day you turn up. Here’s how to book it without setting yourself up to be disappointed.
In a Hurry: Three Boat Tours Worth Booking
Quick picks
- Best budget pick: Capri: Island Boat Trip With Grottos ($28). Two hours from Marina Grande, stops at the Faraglioni and the Green Grotto. Goes whether the Blue Grotto is open or not.
- Best from Naples: From Naples: Gulf of Naples and Capri Sightseeing Tour ($93). Full-day cruise from Naples, around-the-island sail, free time on Capri. The trip you book if you don’t want to deal with the ferry.
- Best Blue-Grotto guarantee: From Naples: Capri and Blue Grotto Day Tour ($173). The pricier option that prioritises Blue Grotto entry when conditions allow, plus the Anacapri chairlift.
The Blue Grotto Reality Check
Every guide leads with “the Blue Grotto glows electric blue.” Fewer mention that it closes the moment the swell picks up, that you transfer from your big boat to a tiny rowing boat to get inside, that the row inside takes about 90 seconds, and that the entry fee (around €18) is not included in most tour prices. The Capresi rowers have been doing this for generations and they have opinions about everything.
I asked a Marina Grande boat captain last year which grotto was actually his favourite. He said the White Grotto, off the southern coast, because it has space to swim inside and you don’t queue for a rowboat. The Green Grotto gets a passing wave and a “yes it’s pretty.” The Blue Grotto got a shrug and “the tourists love it.” That’s been my experience too. The Blue Grotto is genuinely beautiful for the 90 seconds you’re inside it. The rest of the boat trip is what you actually came for.
Practical numbers worth knowing before you book:
- Blue Grotto entry fee: around €18, paid separately to the rower at the cave entrance. Cash is easiest.
- Closure rate: high. The Blue Grotto closes whenever the swell is over about 30cm. Plan a full extra day on Capri or in Naples in case your tour day gets cancelled.
- Best time to enter: midday, when the sun is overhead. Morning and late afternoon trips can reach the cave but the colour is muted.
- Hours: roughly 9am to 5pm, weather depending. Last entry well before sunset.
Naples Or Sorrento Or Capri: Where to Start
Three departure points all pitch themselves as the best base for the boat tour. They’re not equivalent.
From Naples is the option most short-itinerary travellers default to. The ferry from Molo Beverello to Capri runs hourly in summer, takes about 50 minutes on the fast hydrofoil, and costs €25-€30 each way. If you’re already pairing this with a couple of nights in Naples for the pizza, food, and underground, this is the natural plan. The trade-off is travel time: you spend nearly two hours each way in transit before the boat tour even starts.
From Sorrento is the favourite of locals who know the route. The crossing is shorter (about 25 minutes), the boats are less crowded, and the tour operators tend to run smaller groups. If you have a flexible itinerary, Sorrento is where I’d actually base myself for a Capri day. It’s also closer to the Amalfi Coast, so you can pair both into the same trip.
Staying on Capri overnight changes the whole tone of the visit. The day-trippers leave by 5pm and the towns empty out. If you can afford it, one night on the island lets you do the boat tour on a calm morning, take the chairlift to Anacapri without queuing, and walk the Pizzolungo trail past Villa Malaparte at golden hour. Most people don’t, and that’s why most boat tours are crammed.
What the Boat Tour Actually Looks Like
The standard around-the-island tour is roughly two hours. You leave Marina Grande, sail clockwise (or counter-clockwise depending on the swell), and pass:
- The Lighthouse at Punta Carena (the southwestern tip, the photogenic one)
- The Green Grotto (Grotta Verde, an open swim cave on the south side)
- The White Grotto (Grotta Bianca, more of a sea arch, swimmable)
- The Faraglioni (the three big sea stacks, the boat sails through the middle one)
- The Blue Grotto (north coast, transfer to a small rowing boat, optional and weather-dependent)
- Marina Grande (back to where you started)
The Faraglioni is the actual showstopper. Bigger and more dramatic in person than the photos suggest, in the same league as the cliff arches you sail past on a Mallorca catamaran day. The middle rock, called Faraglione di Mezzo, has a natural arch wide enough for the small tour boats to sail through. There’s a Capri tradition that couples kiss as the boat passes through. It’s cheesy, but everyone does it anyway, and the boat captain will usually slow down to let you.
Where the Boat Stops, Where You Get Off
One detail that catches people out: small boat tours might briefly stop at Marina Piccola for a swim, but you don’t get off the island there. Marina Grande is the only working passenger port, and that’s where you board the ferry back to Naples or Sorrento. If your tour pitches “free time on Capri,” that means dropped off at Marina Grande, with two or three hours to take the funicular up to Capri town, eat lunch, and come back. It is not enough time to also get to Anacapri unless you’re moving fast.
Three Tours Worth Considering
1. Capri: Island Boat Trip With Grottos: $28
This is the right pick if you’ve already made it to Capri (or you’re staying overnight) and you just want a short, well-priced boat lap of the coastline. Our review covers the route in detail, including which grottos the smaller groups actually swim into. The Blue Grotto is optional and add-on; expect to pay the rower the entry fee separately.
2. From Naples: Gulf of Naples and Capri Sightseeing Boat Tour: $93
The pick if you only have one day in the Bay of Naples and want everything bundled, with Gaetano-style guides who actually know the bay. Our full review goes into how the timing works around the around-the-island sail and the on-island free time. Blue Grotto entry is weather-dependent and not always included.
3. From Naples: Capri and Blue Grotto Day Tour: $173
Worth the price jump only if the Blue Grotto is the reason you came. Alberto-led groups (one happy traveller wrote that “Alberto was an awesome guide”) tend to skew small, and our review walks through the day-trip mechanics. If conditions cancel the Blue Grotto, you still get the around-the-island sail, but you’re paying premium for what is then essentially the $93 tour above.
What to Skip
Skip any tour that promises “guaranteed Blue Grotto entry” without a weather caveat. The Capresi don’t guarantee it. Operators that do are either lying or going to refuse to refund you when the cave is closed. Read the cancellation terms carefully.
Skip the private yacht charters unless you have a specific reason to pay for one. The €1,000+ private boats sell themselves on flexibility and exclusivity. In practice you sail the same route as the €28 group tour, you reach the Blue Grotto in the same conditions, and you have to wait for the rowboat at the entrance like everyone else.
Skip the long combined tours that try to fit Capri, Sorrento, Positano, and a pizza lunch into one day. You spend most of the day on the boat or the bus and barely walk anywhere. If you want the coast, do the Amalfi Coast as a day trip on its own, and Capri on a separate day.
How to Read the Weather Yourself
The Capresi check two things in the morning: the wind direction and the swell. The Blue Grotto entrance is a hole roughly 1m high. Any swell over 30cm closes it. Westerly winds make the swell worse. The simplest signal: if your ferry from Naples is bouncing, the Grotto is closed. If the crossing is glass, you’re probably going in.
You can pre-check by looking at the wave forecast for the Tyrrhenian coast. Windy.com is the favourite of the boat captains. Anything over 15 knots of wind from the west is bad news.
Capri Town and Anacapri: Worth Combining?
If your boat tour gives you free time on Capri after the sail, you have a choice: stay in Capri town (the famous one with the Piazzetta and the designer shops), or take the bus to Anacapri (quieter, higher up, less polished). Both have a payoff. Capri town has the Gardens of Augustus and the Belvedere over the Faraglioni. Anacapri has the Monte Solaro chairlift, which gets you to the highest point on the island in 12 minutes for sweeping views over the whole Bay of Naples.
You can do one or the other on a typical four-hour-on-island stop. Not both. The bus between the towns is short but slow on summer afternoons. If I had to pick, I’d take Anacapri and the chairlift, every time. The view from the top of Monte Solaro is the best on the island and the queues at Capri town’s shops aren’t worth your time.
Pizzolungo and Villa Malaparte: The Quieter Walk
One traveller on the Rick Steves forum put it well: the further you get from the centre of Capri town, the fewer tourists you encounter. The Pizzolungo trail loops along the southern cliff with views over the Faraglioni from above. It passes Casa Malaparte, the famous red modernist house perched on a rock. About an hour at a slow pace, mostly flat with one set of stairs at the end. Skip it if you’ve only got the boat-tour layover. Do it if you stay overnight.
Compared to the Other Italy Boat Days
Capri is one of three boat-tour days that anchor an Italian trip. The other two are different enough to be worth comparing.
The Venice gondola is a 30-minute thing, mostly atmosphere, and the price-per-minute is brutal. Capri’s boat tour is two hours of actual coastline and you swim. The two products solve different problems; if you only do one in Italy, do Capri.
The Venice islands trip (Murano, Burano, Torcello) is a closer parallel. Both are “multi-stop boat days.” Venice’s is calmer water, more shopping, more glass-blowing demos. Capri’s is rougher water, more swimming, more dramatic coastline. Different countries of the same idea, and the lineup extends sideways to the Ibiza beach cruise (party plus swim) and the Rotterdam harbour cruise (port architecture instead of cliffs).
The Amalfi Coast day trip is the natural pair. Many travellers do both, on consecutive days, from a Sorrento base. The Amalfi day is mostly land-based with a short boat hop to Positano. Capri is the inverse, mostly boat with a short land stop. Together they’re the Bay of Naples experience.
Where to Eat When You Get Off the Boat
The lunch trap on Capri is real. Anything within two minutes of the Piazzetta is overpriced and aimed at the cruise crowd. A few real places to know:
- Da Paolino in Marina Grande, the lemon-tree restaurant. Pricey but the tree-canopy lunch is genuinely lovely. Book ahead in summer.
- Il Geranio in Capri town, with a clifftop terrace and proper Capri salad. About €60 a head with wine.
- Le Arcate in Anacapri, walking distance from the Monte Solaro chairlift. Wood-fired pizza, half the price of anything in Capri town.
- Buonocore for a gelato break (they make a proper Caprese cake too).
If you’re tight on time and just want to eat fast before the ferry back, there’s a string of stalls and cafes inside the Marina Grande ferry terminal area that do panini and granita well enough. Better than a sit-down rush.
When and How to Book
Most boat tours from Naples or Sorrento sell out in summer. Book at least 48 hours ahead in July and August, ideally a week. Shoulder months (May, late September) you can usually book the morning of, except weekends.
The two questions to ask any operator before paying:
- What happens if the Blue Grotto is closed on the day? Do they refund the entry fee? Do they substitute another stop?
- What’s the boat size? A 12-passenger speedboat handles the swell better and reaches the grottos faster than a 60-passenger ferry-style boat.
For free cancellation, GetYourGuide and Viator are the safest paths. Both let you cancel up to 24 hours ahead at no cost on most Capri tours. Direct bookings with Capresi operators are sometimes cheaper but rarely refundable.
What to Bring
Things I always carry on a Capri boat day:
- A swimsuit under your clothes (the Green Grotto and Marina Piccola swim stops are short)
- A microfibre towel that dries fast
- Sunscreen (reef-safe; many operators ban anything else)
- A waterproof phone bag, the cheap zip-lock kind, for the dinghy transfer at the Blue Grotto
- About €25 in cash for the Blue Grotto rower fee
- A long-sleeve cover-up for the wind on the way back (the breeze gets cold even in August)
Don’t bring a hardshell suitcase. Boat operators will refuse to load it. Day-pack only.
If the Day Goes Wrong
The forum advice that opened this article was right. Plan for the boat tour to be cancelled. Build a buffer day. The most common backup, if the seas are bad: ferry to Capri anyway and walk. Skip the boat. Take the funicular up, the bus to Anacapri, the chairlift to Monte Solaro. The island has plenty to see on foot. The boat is the showpiece, but it’s not the only thing.
If the cancellation comes from your Naples-based tour and you’ve got the day open, redirect to Pompeii or Vesuvius. Both are weather-flexible and easier to slot in last-minute. The trains from Naples Centrale run all day.
One Last Note on the Photo
Don’t try to photograph the inside of the Blue Grotto. Phone cameras can’t handle the light, the rower will tell you to put the phone down anyway, and you have 90 seconds inside. Look at the cave with your eyes. Buy a postcard outside afterward if you want a record. The good photos are the Faraglioni from the boat, Marina Piccola from above, and the harbour at Marina Grande as you sail in. Save your battery for those.
Around the Bay of Naples: What Else to Pair It With
If you’ve come this far for the boat day, you’re probably already mixing it with the rest of the bay. The natural pairing for most travellers is two days: one for Capri, one for Pompeii or the Amalfi Coast. If you’ve got three days and you want the full version, throw in a proper Naples pizza night and a morning at Naples Underground. Five days is the version where you can climb Vesuvius and not feel rushed at any of it. The Capri boat day is the splashiest of the lot, and the one that depends most on the weather, so if conditions look good on the day you arrive, do this one first. The rest can flex.
