Tilos has no airport and only a minimal ferry service. The Dodekanisos Seaways catamaran stops at Tilos on Tuesday and Thursday, heading from Rhodes and Halki to Nisyros, Kos and Kalymnos in the morning, and back to Rhodes in the evening. On those days, you can visit the island as a day trip from Rhodes or Halki. In addition, Blue Star Ferries sails twice each week to Piraeus via Nisyros, Kos and Kalymnos, and twice to Rhodes, one of which stops at Symi.
Five buses each day connect Livadia with Megalo Horio, Eristos Beach and Agios Antonios (€1.50). There is no taxi, but you can rent a car or scooter from Drive Rent A Car or Tilos Travel.
