To the northwest of Corfu lie the Diapontian Islands - Mathraki, Othonoi, and Erikoussa. The first of these is surrounded by shelving reefs and the approach is extremely difficult, making the island the most isolated of the group. The other two islands, however, can be considered as the first port of call for vessels approaching from the Adriatic and are thus well-frequented. Their rugged shores constitute a great attraction for nature-lovers. The area from Sidari to the Ag. Spiridon peninsula, for the most part, forms shallow, sandy beaches, ideal for novice swimmers and beach games.
The northeast coast is ideal for exploring by boat, with its easy access to shore, and calm, warm waters. Kassiopi is a colourful harbour, much-frequented by the caiques that operate daily organized excursions. A stroll along its quayside will convince you of the number and variety of cruises on offer. In the 4th century B.C., this was an important Roman port, dedicated to the god Kassios Zeus, protector of seafarers. Between Kassiopi and Barbati the coastline is sculpted into a chain of small bays and coves, ideal moorings for all types of vessel. Agios Stefanos, Kouloura, Kalami, Agni are just a few of the place-names you will come across.

The west coast of Corfu has the most variety. Its northern section, with a rugged, rocky coastline, is crowned by the cliffs of Palaiocastritsa, ideal for exciting underwater exploration, where the small harbour offers a safe anchorage and cosmopolitan entertainment. Further south, the landscape softens and there are endless beaches of golden sand lapped by an aquamarine sea. For the good swimmer, this is the place to enjoy some sport in the surf. For yachtsmen, this stretch of coastline has no particular interest as it does not form bays and has many reefs.
South of the town of corfu and to the east, the shoreline is level and the shallow water ideal for swimming. Just before Kavos (Lefkimmi) is the small fishing harbour of Petreti, where a stop for a meal of freshly-caught fish is highly recommended. The unique beauty of the coastline of Paxos is renowned throughout the Ionian. The natural harbours of Lakka, of Gaios and Mongonisi teem with boats in the summer months. The importance of the anchorage they offer increases when the maestro blows and the microclimate is a refuge from the currents and the swell of the Paxos straits. The west coast of the island forms impressive cliffs with sea-caves and underwater caves which must be visited when the weather permits. Anti-Paxos, while not offering any safe anchorage, is much visited for the fantastic beaches and aquamarine water of its northeastern coast.
