Greece Upgrades Diapontia Islands Port Facilities and...

The Ministry of Tourism of Greece has announced a targeted infrastructure strategy to upgrade port facilities and maritime transport links connecting Corfu with the Diapontia Islands (Othonoi, Mathraki, and Ereikousa). Following official site inspections on August 24, 2026, the plan establishes low-density, sustainable island-hopping corridors across the northwestern Ionian Archipelago.

Greece is expanding its sustainable tourism model by directing visitor movement toward lesser-known island clusters while safeguarding local community character. Tourism Minister Olga Kefalogianni and Ionian Islands Regional Governor Yiannis Trepeklis conducted a joint delegation visit on August 24, 2026, to inspect harbor facilities, outline land infrastructure funding, and establish a long-term destination management framework for the Diapontia group.

Maritime Infrastructure Strategy Across the Diapontia Archipelago

Situated off the northwestern coast of Corfu, the Diapontia Islands represent the westernmost territory of Greece. Because these remote island communities lack airports, their economic viability and resident mobility rely entirely on maritime ferry links with northern Corfu.

The government's development model focuses on enhancing transport resilience, improving port berths, and expanding seasonal maritime frequencies from Corfu. This strategy enables international travelers staying on Corfu to easily incorporate multi-island day trips and overnight slow-travel itineraries.

Individual Island Characteristics and Geographical Parameters

The strategy coordinates individual development plans tailored to the distinct scale and natural environment of each island:

Othonoi (Northwesternmost Point of Greece): As the largest island in the cluster, Othonoi features a coastline spanning 30 kilometers and is located approximately 12 nautical miles from northern Corfu. It offers secluded coves, traditional stone settlements, and historic maritime lighthouses.
Mathraki: The smallest of the three islands, Mathraki is characterized by compact harbour bays, sandy beaches, and quiet footpaths, linked to Corfu via small-boat harbour transfers.
Ereikousa: Located closest to northern Corfu, Ereikousa provides a low-density green environment with shallow sandy bays ideal for sailing and marine excursions.

Diapontia Island Infrastructure and Transit Specifications

Official parameters established by the Ministry of Tourism, the Region of Ionian Islands, and municipal authorities outline the scope of the project:

Parameter	Official Specification
Geographic Location	Ionian Sea, Northwest of Corfu, Greece
Primary Gateway Port	Agios Stefanos Avliotes & Sidari (Northern Corfu)
Distance to Othonoi	Approx. 12 nautical miles from northern Corfu
Othonoi Coastline	30 kilometers of natural maritime coastline
Target Travel Demographics	Slow travelers, nature tourists, sailors, hikers
Managing Governance Body	Ionian Islands Destination Management Organisation (DMMO)
Regulatory Policy Framework	Special Spatial Planning Framework for Tourism

Traveler Logistics & Island-Hopping Ferry Routes

Travelers seeking an authentic, uncrowded Ionian island experience can navigate the Diapontia group via organized ferry routes from Corfu.

Ferry Access and Departure Hubs

From Agios Stefanos Avliotes (Northwest Corfu): The primary year-round passenger and vehicle ferry terminal serving Othonoi, Mathraki, and Ereikousa.
From Sidari: Seasonal high-speed passenger passenger launches operate morning excursions to Ereikousa and Mathraki during summer months (May through September).
From Corfu Town Port (Kerkyra): Regional passenger ferries operate scheduled multi-stop services connecting the capital port to all three Diapontia islands.

Traveler Optimization Tips

Weather Buffer Allowance: Maritime transit across the northern Ionian Sea can be subject to localized wind variations (meltemi or squalls). Travelers should build a 24-hour buffer when connecting to onward flights at Corfu International Airport (CFU).
Accommodation Planning: Because guesthouse capacity on Mathraki and Ereikousa is limited, visitors planning overnight stays should book family-run accommodations well in advance.
Specialized Eco-Tourism Activities: The islands are best explored on foot or by boat; marked hiking trails link Othonoi's interior hamlets to Calypso Cave and Fyki Bay.

Governance Framework and Special Spatial Planning Controls

To prevent over-commercialization, the Greek government is managing growth through the newly established Destination Management and Promotion Organisation (DMMO) for the Ionian Islands Region. Concurrently, the joint Special Spatial Planning Framework for Tourism—signed by the Ministry of Tourism and the Ministry of Environment and Energy—imposes strict building density limits and environmental protections across small island ecosystems.

This balanced policy ensures that enhanced ferry connections and upgraded port facilities generate local economic resilience for permanent residents without altering the quiet identity of Greece's smallest island communities.
