Overlooking the indigo-blue Ionian Sea and surrounded by countryside planted with silvery groves of gnarled olive trees, The Romanos, Costa Navarino in Greece’s southwestern Peloponnese is one of Andrew Harper’s most family-friendly recommended properties in the Mediterranean. The resort complex has two separate children’s clubs (for ages 8 months to 5 years and 5 years to 12 years), its own natural history museum and a popular sleepover program on the weekends. Tennis and golf classes are available, as well as an aqua park with slides and waterfalls (pictured). Nearby archaeological attractions include the Mycenaean ruins of King Nestor’s Palace and Olympia, the site of the Olympic Games in classical times. Please visit here to read Mr. Harper’s full review.
