The Delos Archaeological Site covers almost the entire tiny, uninhabited island of Delos in the Cyclades, a short boat ride from Mykonos. Revered in Greek mythology as the birthplace of Apollo and Artemis, it grew into one of the ancient Mediterranean's greatest sanctuaries and cosmopolitan trading ports, and was inscribed as a UNESCO World Heritage Site in 1990. As of 2026 the island still has no hotels, shops, or shade, so it can only be visited as a day trip by boat — an open-air museum you explore entirely on foot.
The Terrace of the Lions, marble lions dedicated by the Naxians around 600 BC (five remain on site; the originals are in the museum)
The Sanctuary of Apollo and the Sacred Lake, the legendary birthplace of Apollo (now drained)
The floor mosaics of the Theatre Quarter mansions, above all the House of Dionysus (Dionysus riding a panther)
Mount Kynthos (113 m), with panoramic views over the Cyclades and Egyptian and Syrian sanctuaries near the summit
The Archaeological Museum of Delos, displaying original sculptures and excavation finds
Good to know
SafetyThe terrain is uneven ancient stone and marble; wear sturdy closed shoes and take care on the Mount Kynthos climb.
SeasonThere is almost no shade and the summer sun is fierce — bring plenty of water, a hat and sunscreen, and take an early boat to avoid the midday heat.
SeasonThe Meltemi wind can delay or cancel ferries in summer, so keep your schedule flexible; ferries generally run only from April to November.
RulesThe last return ferry leaves at a fixed time and there is no accommodation on the island — confirm the timetable and do not miss the boat.
RulesThis is a protected UNESCO site: do not remove stones or artefacts, climb on the ruins, or leave the marked paths (penalties apply).
CautionBuy ferry tickets from official operators at Mykonos Old Port and check whether the price includes a guide and the separate site entry fee.
Practical info
Delos is reached only by boat (about 30 minutes) from Mykonos Old Port; ferries run roughly April–November, Tuesday–Sunday with limited Monday service and a last return in the afternoon. The combined site-and-museum ticket is bought on site (ferry fare separate), and summer opening is about 08:00–20:00 (shorter in November). Confirm current fares and timetables before you go.
