From their comparison of price data for summer 2025, the foundings were:

• On average, you'll spend over €1,000 for a crossing for two people, a cabin, and a car. This figure, however, doesn’t reflect the length of the crossing in either time or distance.
• The most expensive crossing is from Denmark to Iceland: €2,222. This includes two overnight stays each way (four in total).
• When calculated per kilometre (€0.73), this crossing is relatively affordable. Per hour (the crossing lasts 66 hours one way, so 132 hours round trip), it costs just €17 per hour for two people. By comparison, the ferry from Barcelona to Ibiza (8 hours) costs nearly four times as much per hour on board.
• Direct ferries from the Netherlands to England cost between €620 and €845 return. This includes two overnight stays for two people, the journey, and your car.
• Interesting find: Ferries from the UK and Ireland to Spain are cost-effective per kilometre. This is a great option if you want to combine Southern England (Devon, Cornwall, etc.) with Spain. For example, the ferry from Portsmouth to Bilbao costs €1,156.
• Ferries to the Balearic Islands (Ibiza and Mallorca) are more expensive, with both crossings costing over €1,000 for a distance of less than 300 kilometres.
• Generally, longer crossings are more affordable per kilometre. For instance, the ferry from Germany to Finland, one of Europe’s longest crossings at 1,092 kilometres, costs just €0.50 per kilometre. Similarly, the crossing to Scotland (IJmuiden-Newcastle) is cost-effective.
• The cheapest crossing per kilometre is one of the least known: from Barcelona to Civitavecchia, near Rome, costing just €0.44 per kilometre for two people.
• The ferry from France to Morocco (Sète-Nador) is also among the more affordable options.
• The lowest overall cost in this study is for the crossing to Trelleborg (Sweden) from Rostock (Germany).
• There are significant price changes compared to 2024: for instance, the Newcastle crossing is 22.5% cheaper, while the ferry from Liverpool to Belfast has increased by 51%. Great news for Scotland-bound travellers, less so for Northern Ireland.
• On average, prices per kilometre have increased by 5.4%, or about €23 more.

The analysis focused on return crossings with a standard inside cabin where possible. Data was collected for travel from 5 to 12 July 2025, including a car.

Ferry costs summer 2025
Here’s an overview of the costs for a return trip in high season for two people, including a standard inside cabin and car.

Key Takeaways

• Longer routes tend to offer the best value per mile, especially for travellers heading to the Nordics or North Africa.
• Island crossings (e.g., Mallorca, Ibiza, Guernsey) are disproportionately expensive compared to other crossings. mainly because they're shorter in general so less efficient.

By carefully selecting routes and planning ahead, ferry travel can be an economical and enjoyable way to explore Europe and beyond.

A few tips:

• Travelling by car? Book early. Foot passengers have more flexibility, but car decks on ferries fill up quickly, and prices will rise as space becomes limited.
• Do the math on whether it's worth bringing your vehicle. For longer trips, the savings can often justify the cost.
• Take advantage of early booking discounts. Booking early—usually by early February—can secure you discounts. For instance, DFDS and Stena Line currently offer 20% off crossings.
