A car park opened in spring 2012 in Metohi (€5/day) on the Peloponese coast directly opposite Hydra. Hydra Lines (tel. +30 6947 325263, www.hydralines.gr) runs a regular crossing from there to the island in the Saronic Gulf costing €6,50/person and takes 15 minutes.
Now you have no difficulty getting to Hydra by road. It takes 2 hours and 45 minutes from Athens on the Athens-Korinth National Road. Exit at Epidavros and leave your car in safe hands at the car park while you enjoy your trip or vacation on the majestic island.
