Sacred island of Apollo and ancient trading port, a UNESCO World Heritage Site off Mykonos
Delos is a small, rocky island of about 3.4 square kilometres lying just south-west of Mykonos, yet in antiquity it was one of the most sacred places in the Greek world. According to myth Apollo and Artemis were born here, and the sanctuary of Apollo drew pilgrims from across Greece for centuries. Today the whole island is an archaeological site, with no permanent residents and nowhere to stay overnight.
Stepping off the boat, you walk among the remains of temples, colonnades, markets, houses with mosaic floors and a marble theatre, with the hill of Mount Kynthos rising above. The weathered lions of the Terrace of the Lions, wild flowers in spring and the surrounding blue sea make it a striking place. Most visitors come as a half-day trip from Mykonos, and a few hours on the island give a vivid sense of a city that once linked the whole eastern Mediterranean.
Traces of settlement on Delos go back to the 3rd millennium BC, and by the Archaic period the sanctuary of Apollo was a major religious centre. Shortly before 600 BC the people of Naxos dedicated a row of marble lions along the Sacred Way, seven of which survive. In the 5th century BC the island held the common treasury of the Delian League until Pericles moved it to Athens in 454 BC, and Athenian purifications later banned births and burials on the island.
In 166 BC Rome made Delos a free port, and it became a crowded commercial hub of the eastern Mediterranean, home to merchants from many lands and their temples and houses. Attacks during the Mithridatic Wars in 88 and 69 BC began a long decline, and the island was eventually abandoned. Excavations began in 1872 and continue today. UNESCO inscribed Delos on the World Heritage List in 1990.
Delos has no village or permanent population; apart from site staff and archaeologists, it is uninhabited, and visitors must leave on the last boat. Its connection with daily life now runs through Mykonos, whose boatmen and guides ferry visitors across each morning, and whose Archaeological Museum displays further finds from Delos and neighbouring Rhenia. For Greeks, the island remains a powerful symbol of the ancient religious and commercial world of the Aegean.
Plan on two to four hours on the island to see the main areas and the museum. A sensible route follows the Sacred Way to the sanctuary of Apollo and the Terrace of the Lions, then crosses to the theatre quarter, where houses with mosaics line the old streets. If you have the energy, climb Mount Kynthos, a short but steep walk, for a panorama over Delos, neighbouring Rhenia and Mykonos.
Many visitors join a guided tour from Mykonos, which helps make sense of the scattered ruins. Private boat trips can add a swim off uninhabited Rhenia on the way back. Spring is especially rewarding, when the site is carpeted with wild flowers.
Spring (April to June) and autumn (September to October) are ideal, with gentler temperatures and fewer crowds; in spring the ruins are surrounded by flowers. In July and August the island is very hot with almost no shade, so take an early boat. Boat services depend on the weather and can be cancelled in strong winds. The site closes in winter, from December to March, except by written request.
