The Kea (Tzia) to Kythnos ferry is one of the Cyclades' most popular connections, operating 3-5 times per week with journey times from 40m to 1h 12m and tickets from €8.00. The route is served by Fast Ferries, with vehicle transport available on conventional ferries. Service runs year-round.
Kythnos is celebrated for its natural thermal hot springs at Loutra, dozens of secluded beaches, traditional villages with narrow alleyways, and authentic off-the-beaten-path charm. Whether you're drawn by the beaches, the local cuisine, or the authentic Cycladic atmosphere, Kythnos rewards visitors who make the crossing.
Insider Tip: The Kea to Kythnos crossing is one of the Aegean's most scenic routes. Grab a seat on the outdoor deck for unbeatable sea views. Traveling mid-week usually means emptier ferries and a more relaxed arrival. In peak season, book at least 2–3 weeks in advance to secure your preferred departure time.

Travel Tips
Port of Korissia is Kea's only port, on the northwest coast — just 1 hour from Lavrio on the mainland. The port is popular with Athenians for weekend escapes, meaning it gets very busy on Friday evenings and Sunday afternoons. Buses to Ioulida (the capital, 8 km) run in summer. Taxis cost €10–12 to Ioulida. Arrive 30–45 minutes before departure on busy weekend days. The port area has cafés and a small supermarket.
Arriving in Merichas, Kythnos reveals itself as one of the most genuinely Greek of the Cyclades islands — minimal foreign tourism, excellent tavernas, and the famous therapeutic hot springs at Loutra (10 km from the port). The thermal baths at Loutra, used since antiquity, are ideal for relaxation. The island's twin villages, Chora and Dryopida (with its remarkable cave), are 8 km from the port. Kythnos is ideal for a quiet Cyclades escape away from the summer crowds.
