Sardinia and Corsica are the two western-Mediterranean islands that anchor what is, when chartered well, the strongest 7-day-loop in the region. The Bonifacio Strait separating the two is the central feature of the routing. Most clients reading this page are choosing between three answers: Sardinia only (typically a Costa Smeralda week), Corsica only (typically a south-Corsica-and-Lavezzi loop), or the combined Sardinia-Corsica week, which is the routing we recommend most often for the 50m-plus charter at the upper rate band. The loop covers 80 to 140 nautical miles and threads two islands that have, by Mediterranean standards, almost nothing in common culturally.
We rank yachts in both regions on our best charter yachts Mediterranean 2026 page and the Costa Smeralda charter and Corsica charter pages cover the destination detail. The four cases that decide the week, plus the contested middle, sit below.
The 30-second verdict
Pick Sardinia (Costa Smeralda) if your brief is roughly "Porto Cervo Marina at the load-bearing anchor, Phi Beach or Cala di Volpe lunch, beach-club shoreside, and a yacht of 50m-plus in the inventory band the Costa Smeralda specifically attracts." Sardinia is the social-and-scene-led half of this comparison. Pick Corsica if your brief includes any of: a Bonifacio old-town anchor, a Lavezzi Islands swim day, a hiking-led shoreside element on Cap Corse or the Désert des Agriates, or a more open cruising routing with longer daily distance. The fourth case below covers the combined loop. The contested middle is the 7-day Sardinia-only versus 7-day Corsica-only on a 35m to 45m yacht with a mixed brief.
The structural similarities
Both islands run May through October as the operating window, with peak weeks mid-July through late August at rates 30 to 50 percent above shoulder. Both have settled water inside the protected coves (the Costa Smeralda's Pevero, Romazzino, and Liscia di Vacca anchorages; Corsica's Bonifacio cliffs, the Lavezzi Islands, and the Golfe de Porto). Both run MYBA-contract standard at 24m-plus, with APA at 30 to 35 percent of the charter fee.
Both islands also share the structural challenge of the Bonifacio Strait, which is the load-bearing routing variable for any combined cruise. The strait is 7 nautical miles wide at its narrowest, exposed to mistral and tramontane, and can deliver a 35-knot afternoon transit on calm-morning forecast days. Captains know this. Charter clients should also know it. The strait will route around itself in the right weather window. The week's itinerary should not assume a 4 PM crossing.
The differences sit in cruising culture, geography, infrastructure, and what each island's shore experience gives the charter client beyond the yacht. We work through them next.

The dimensions that decide most reader decisions on this page are beach-club culture and marina infrastructure. We explain both below.
Where Sardinia wins
Sardinia (specifically the Costa Smeralda) is the region we recommend on four specific kinds of charter weeks.
The first is the Porto Cervo Marina-led week. Porto Cervo Marina is the marquee yacht-scene marina in the Mediterranean by inventory density at peak August. A 60m-plus yacht booked stern-to in Porto Cervo Marina in the second week of August is in a marina with 20 to 40 other 60m-plus yachts, and the social-and-business density of the marina at that week is at a level only Monaco for the Grand Prix matches. A charter client whose brief is partly about being in this marina at this week should book Sardinia.
The second is the beach-club-led shoreside week. The Costa Smeralda beach-club stack (Phi Beach, Cala di Volpe, Petra Niedda, the Hotel Cala di Volpe at the Pevero) is the densest in the western Mediterranean. A 50m-plus yacht based at Porto Cervo for a peak August week can deliver a different beach-club lunch each day without changing anchorage by more than 4 nautical miles. Corsica does not have this density.
The third is the 70m-plus charter week with a Costa-Smeralda-specific brief. The 70m-plus inventory at Costa Smeralda in August is the deepest western-Mediterranean concentration in the size class. Brokers will route 80m-plus charter clients to the Costa Smeralda by default if the brief includes the marina scene. Corsica is a viable port-of-call for these yachts as a Bonifacio day stop, but the week's anchor is structurally Sardinia.
The fourth is the social-photography week. The Costa Smeralda in the second and third weeks of August carries a social-photography density comparable to Saint-Tropez or Mykonos. Phi Beach at sunset, Cala di Volpe at lunch, and the Porto Cervo Piazzetta at midnight are three named social-photography venues with consistent international yacht traffic. For a client whose week is partly defined by the social scene, Sardinia is the better answer.
Where Corsica wins
Corsica is the region we recommend on four specific kinds of charter weeks.
The first is the Bonifacio old-town anchorage week. Bonifacio is the medieval cliff-top citadel at the south end of Corsica and the marina is one of the most distinctive in the Mediterranean, cut into a fjord-like inlet. A 40m-to-55m yacht booked stern-to in Bonifacio for two nights of the week delivers a shoreside register that the Costa Smeralda does not match. The old-town walk, the cliff views, and the late-evening light on the citadel are not replicable anywhere else in the Tyrrhenian.
The second is the Lavezzi-and-Strait-of-Bonifacio swim week. The Lavezzi Islands granite outcrops in the Strait of Bonifacio deliver the most distinctive swim anchor in the western Mediterranean. Clear water over white-sand bottom, granite-island geometry, and minimal congestion outside the August peak. A charter brief that prioritizes the swim experience should route a meaningful fraction of the week through the Lavezzi.
The third is the hiking-led shoreside week. Corsica's interior (the GR20, the Désert des Agriates, the Bavella range) and the coastal hiking from Saleccia to Loto are at a level no Sardinian shoreside hiking match. A charter client whose week includes one or two half-day hikes will get a meaningfully more interesting Corsican experience than a Sardinian one.
The fourth is the lower-pressure cruising week. Corsica's peak August is busy but is structurally less congested than the Costa Smeralda peak. The marina pressure is lower, the beach-club lunch reservations are easier, and the cruising routing has more room. For a client who wants a Mediterranean week without the scene density, Corsica delivers a better week at a 15 to 25 percent lower rate.
Where the combined loop wins
The combined Sardinia-Corsica week is the routing we recommend most often for the 50m-plus charter at the upper rate band. The loop typically runs Olbia or Cagliari to the Maddalena, across the Bonifacio Strait in a morning weather window, two days in Bonifacio and the Lavezzi, a return to Costa Smeralda for the second half of the week, and a finish at Porto Cervo or back to Olbia. The total distance is 100 to 140 nautical miles. The shore experience delivers both the Bonifacio cliff-top and the Costa Smeralda beach-club scene. It is the most varied Mediterranean week we recommend at the 50m-plus level.
The combined loop is also harder to deliver than either single-island week, because the Bonifacio Strait crossing requires a captain who has the weather window judgment, and the routing assumes flexible itinerary management. Brokers who route combined loops well will adjust the day-by-day on the strait crossing rather than fixing it in advance. Brokers who do not should not be running this routing.
Where it is too close to call
On the 35m to 45m motor yacht booking for a peak week with a generic brief (some cruising, some social, some swim), the two islands are interchangeable on yacht quality. The decision in this band comes down to whether the client wants the social-scene weight (Sardinia) or the cruising-variety weight (Corsica). Both deliver good weeks.
On the shoulder-week booking (mid-May to mid-June, mid-September to mid-October), both islands deliver excellent weeks at 30 to 40 percent below peak rates. The shoulder Costa Smeralda is genuinely the best version of the Costa Smeralda, with the marina open and the beach clubs running but the scene density at 30 percent of August. The shoulder Corsica is similarly excellent. In this band, both are top choices.
On the family week with mixed ages and a brief that splits across cruising, swim, and shoreside, both islands can deliver, with a slight edge to Corsica for parties with hiking-interested teenagers and a slight edge to Sardinia for parties with social-scene-interested adults.
Three myths to ignore
"Sardinia is the more expensive island." Roughly true and worth quantifying. The weekly rate on a comparable 50m yacht in the Costa Smeralda runs 15 to 25 percent above Corsica at peak. The marina fees in Porto Cervo at peak August can run €5,000 to €8,000 per night for a 50m yacht versus €1,500 to €2,500 in Bonifacio. The gross spend on a Sardinia week including dockage and beach clubs is meaningfully higher than a Corsica week on the same yacht.
"Corsica is the less polished charter destination." Partly true and partly outdated. The Corsican charter infrastructure has matured significantly over the last decade, with credible brokers operating out of Bonifacio and Calvi and a serviceable marina infrastructure across the south and west coasts. Corsica is less yacht-scene-polished than the Costa Smeralda. It is not under-developed.
"The Bonifacio Strait crossing is dangerous." Overstated. The strait requires weather-window judgment and a competent captain. It is not structurally dangerous in the right conditions. The captains who run the combined loop weekly will route the crossing in the right window every time. A charter client should hear the captain's planning on the day and not push for a fixed itinerary that requires a specific crossing time.
What we would change about both
Sardinia we would change on the Porto Cervo Marina rate discipline at peak August. The marina at peak is the most expensive in the Mediterranean on a per-meter basis, and the rates are not always disclosed upfront. A 60m yacht booking three nights in Porto Cervo in the second week of August can pay €18,000 to €25,000 in dockage alone, which is a real fraction of the APA. Brokers should disclose this on the front end. Most do not.
Corsica we would change on the marina capacity in Bonifacio at peak. The Bonifacio inlet is geographically constrained and the marina capacity for 40m-plus yachts is limited. A peak August booking that includes two nights in Bonifacio should be confirmed at the marina level by the broker on the front end. A late booking that arrives in Bonifacio without a confirmed berth can end up at anchor in the cala, which is workable but not the experience the client expected.
Both we would change on the Bonifacio Strait crossing weather-window planning. Brokers and captains who route this crossing well will deliver the week. Brokers and captains who treat it as a routine 90-minute transit will deliver a memorably uncomfortable afternoon at some point in the season. A charter client should ask the captain on day one how the crossing will be timed and what the weather-window plan is.
FAQ
Which is easier to fly into? Olbia for Sardinia (1.5 hours from London, direct from major European cities in summer). Figari for south Corsica or Calvi for north Corsica (similar window from major European cities, fewer direct US routes). Olbia has marginally better connections at peak.
Can I do both in 7 days? Yes, with a captain who knows the routing. The combined loop is 100 to 140 nautical miles and fits a 7-day window with 2 nights in Bonifacio and 3-to-4 nights on the Sardinian side, plus the strait crossing.
What is the best week for either? For both, the first week of July before the August peak, or mid-September. Both are 25 to 35 percent below peak rates and the weather is settled.
Is the swim experience different? Yes. The Lavezzi (Corsica) and the Maddalena Archipelago (Sardinia, specifically Spargi and Budelli) both deliver excellent swim anchors. The Lavezzi has the granite-island geometry and lower density. The Maddalena has the broader bay-and-cove variety. Both are top-tier Mediterranean swim destinations.
Are crew gratuities comparable? Yes. 10 to 15 percent of the charter fee for both regions. The how to tip yacht crew guide covers the bands.
The close-call default
For a reader who has narrowed the choice to these two and cannot decide on the edge-case framework above, the close-call default is Sardinia (Costa Smeralda) for social-scene-and-marina-led weeks, Corsica for cruising-and-shoreside-led weeks, and the combined loop for 50m-plus weeks where the client wants the variety of both. In the contested middle on a 35m to 45m yacht, default to Corsica for first-time charter clients (lower pressure, easier marinas) and Sardinia for second-time-plus charter clients who want the scene density.
The deeper rule is to read the Costa Smeralda charter and Corsica charter pages alongside this comparison. Both carry the destination-specific inventory, the marina detail, and the broker referrals. The combined loop is mentioned on both pages with the routing detail.
