Opa! Kefalonia revealed as the cheapest Greek island for British travellers

20 March 2026

Kefalonia has emerged as the most affordable Greek island for UK tourists.

Kefalonia offers authentic Greek charm without the high prices of Kos or Santorini

While many holidaymakers associate a Greek holiday with expensive hotspots such as Mykonos or Santorini, Kefalonia offers the same iconic landscapes - whitewashed villages, turquoise bays, and sun-drenched beaches - at a fraction of the cost.

Research from TravelSupermarket shows that a seven-night stay on the island averages £596 per person, making it significantly cheaper than Kos (£943) and Corfu (£822).

The study analysed bookings made between September 2025 and March 2026 and calculated average per-person costs for seven-night breaks.

The analysis highlights Lefkas (£606), Santorini (£637), Mykonos (£670), and Rhodes (£689) as other cost-conscious options, with Crete (£768), Naxos (£890), and Skiathos (£958) rounding out the top ten.

Despite its reputation as a luxury destination, Mykonos ranked lower than Crete, demonstrating that widely perceived “expensive” islands are not always the priciest.

TravelSupermarket has identified several cost-saving “destination swaps.” Visitors can exchange Kos for Rhodes and save £254 per person, Corfu for Lefkas to cut £216, Skiathos for Naxos to save £68, Crete for Mykonos to save £98, and Santorini for Kefalonia to reduce costs by £41.

Each alternative provides traditional Greek scenery, beaches, and village life at a lower price point.

Chris Webber, Head of Holidays and Deals at TravelSupermarket, said: “Greek islands are not all created equal when it comes to price. Rhodes is significantly cheaper than Kos, and Mykonos can be more affordable than Crete. Small changes in destination can deliver substantial savings without sacrificing the Greek holiday experience.”

Kefalonia’s combination of turquoise bays, cliffs, and quiet villages makes it particularly appealing to travellers seeking value and authenticity, offering a more relaxed experience than the crowded streets and soaring hotel rates of Santorini or Corfu.
