The harbor of Hydra is always very crowded in high season and is best avoided at that time. Early spring is the best time to visit, when it is usually possible to moor either on the south quay or the inside of the north breakwater (where, however, it shallows as you go further in).
As Poros town is built on a small peninsula surrounded by quays, along the south and northwest sides, the harbour provides excellent shelter all year round. The closest airport to Poros island is the International Airport of Athens (IATA: ATH) and from the airport or the city centre, visitors can go to the port of Piraeus and take the ferry to Poros.
Lagoudera, the previous name of Omilos bar-restaurant, was one of the most famous restaurants in Greece, visited by many international celebrities, such as, The Beatles, the Rolling Stones, Jackie Kennedy, Maria Callas and Aristotelis Onassis. It is situated in an excellent location, with amazing sea views and atmosphere.
Kallianos Diving Center was founded in 1990 on Kapari, a small island measuring 10 acres just two miles from the town of Hermione. The center has operated for almost 20 years putting customer service and safety first, and is one of the longest-running diving centers in Greece, and perhaps the only one located on a small island in the entire world.
