Boat Excursions in Corsica

Corsica boasts over 1,000 kilometres of coastline, and some of its most spectacular landscapes can only be fully appreciated from the sea. From red granite cliffs sculpted by the waves to sea caves carved in limestone, from roadless nature reserves to remote archipelagos offshore, boat excursions are a unique and unforgettable way to discover the island.

This guide covers the four unmissable maritime destinations in Corsica: the Scandola Reserve and Girolata, the Piana calanques, the Bonifacio cliffs and the Lavezzi Islands. Each one offers a distinct experience, and together they form a maritime tour of Corsica that every visitor should consider.

Four outstanding maritime destinations

The Scandola Reserve and Girolata village

Listed as a UNESCO World Heritage Site, the Scandola Nature Reserve is the crown jewel of the Corsican coastline. Accessible only by sea, it harbours extraordinary volcanic formations, waters of surreal clarity and protected marine wildlife including ospreys, dolphins and groupers. The village of Girolata, tucked at the head of a gulf with no road access, is the perfect stopover during this iconic excursion.

Trips to Scandola typically last from a half-day to a full day. Departures run mainly from the ports of Porto, Cargese and Calvi. It is the most popular boat excursion in Corsica, and rightly so.

The Piana calanques seen from the sea

The Piana calanques are famous for their red and orange rocks plunging into a turquoise sea. While the D81 road offers striking viewpoints from the heights, it is from the water that the full grandeur of these geological formations becomes apparent. Sea caves, natural arches and rocky pinnacles take on a spectacular dimension when viewed from sea level.

These excursions are often combined with a visit to Scandola on a full-day outing. Boats hug the cliffs closely, allowing passengers to enter some of the cavities and photograph the play of light on the rock.

The cliffs and caves of Bonifacio

At the far south of Corsica, the Bonifacio cliffs present a unique geological spectacle. The upper town, perched on white limestone cliffs that tower 70 metres above the sea, is even more impressive seen from below. The boat trip reveals the sea caves, including the famous Sdragonato grotto, and passes beneath the King of Aragon's Staircase carved into the cliff face.

Departures from Bonifacio harbour are short (around 1 hour) and suitable for everyone, making this an ideal excursion for families or travellers with limited time.

The Lavezzi Islands: a paradise archipelago

Off the coast of Bonifacio, the Lavezzi archipelago is a string of granite islets set in waters of Caribbean-like colours. A protected nature reserve, the Lavezzi offer white sandy beaches, crystal-clear waters perfect for snorkeling and a fascinating mineral landscape sculpted by wind and sea spray.

The crossing from Bonifacio takes just 30 minutes, and most packages include 2 to 4 hours of free time on the main island. It is one of the most popular excursions in southern Corsica, and the beauty of the setting more than lives up to its reputation.

Choosing your type of boat

Standard sightseeing boats

Sightseeing vessels carry between 50 and 200 passengers. They offer stability, comfort (toilets, bar, shaded deck) and affordable fares. Commentary is provided by a guide or by the captain. This is the best option for families and anyone prone to seasickness.

Rigid-inflatable boats

Rigid-inflatable boats (RIBs) carry between 8 and 12 passengers. Faster and more manoeuvrable, they allow you to get closer to caves and cliffs, access coves unreachable by larger vessels and make multiple swimming stops. The experience is sportier and more immersive, but also more exposed to sea spray.

Private boat hire

For complete freedom, hiring a boat with or without a skipper lets you design your own itinerary. Without a boat licence, you can opt for a vessel under 6 horsepower (no licence required) or hire a skipper. With a coastal licence, the options are plentiful: sailboat, catamaran, motorboat. It is the most expensive option but also the most customisable.

When to go: maritime weather in Corsica

The Mediterranean around Corsica is generally calm from April to October, but two weather phenomena can disrupt outings at sea:

The libeccio, the prevailing west-south-west wind, mainly affects the west coast (Scandola, Piana, Porto). When it blows hard (above 25 knots), excursions to Scandola are cancelled. The east coast and the south then become attractive alternatives.

The mistral and the tramontane, northern winds, primarily affect Cap Corse and the Strait of Bonifacio. Crossings to the Lavezzi may be cancelled when seas are rough in the strait.

In practice, the months of June to September see the highest number of calm-sea days. Weather cancellations remain rare across the season as a whole, but it is wise to build a buffer day into your plans.

Practical tips for your boat trips

What to bring on board

Pack a swimsuit, a towel, water-resistant sunscreen, sunglasses with a strap, a hat and a water bottle. For snorkeling, bringing your own mask and snorkel is preferable to using borrowed equipment. Also bring a light windbreaker: even in fine weather, the speed of the boat creates a cool breeze.

Seasickness: how to avoid it

If you are prone to seasickness, choose larger boats for greater stability. Take an anti-nausea medication 30 minutes before boarding. Stay outside and focus on the horizon rather than looking inside the boat. Shorter excursions (Bonifacio, Lavezzi) are better suited than long full-day outings.

Respect for the environment

Corsican waters harbour exceptional marine biodiversity. The Scandola and Lavezzi reserves enforce strict rules: no fishing, no throwing anything into the water, no collecting shells or sand. Boats are not allowed to drop anchor in certain protected zones. Please follow these rules to help preserve this unique natural heritage.

Working boat trips into your itinerary

Sea excursions pair perfectly with overland exploration of Corsica. After a day on the water in the Gulf of Porto, follow up with a hike in the Porto and Piana region. From Bonifacio, alternate between a boat trip and a walk along the coastal footpaths.
