Ammoudi Bay

Stand at the western tip of Oia and look straight down, and you will see a cluster of small buildings and boats squeezed between the sea and towering cliffs of red, black and rust-coloured volcanic rock. That is Ammoudi, the old harbour of Oia, and one of the most atmospheric corners of Santorini. For centuries it was the working port for the village above, and it still is a functioning municipal harbour: the Municipal Port Fund of Thira lists it as the port that serves Thirasia across the bay, with scheduled and cargo boats, a mooring area for the local fishing fleet, and the tender boats that have carried cruise passengers here since 2014. There is no breakwater because the sea drops away so steeply, which is why the little quay feels so exposed and so dramatic. What brings most visitors down, though, is the setting and the food. A short row of fish tavernas lines the waterside, with tables right at the edge of the quay, and eating grilled fish or octopus here while the light fades over the caldera is one of the island's classic experiences. Many people walk down from Oia in the late afternoon, eat early, and either watch the sunset from the harbour or climb back up for the view from the castle. Others come for a swim from the rocks around the bay, where the water is deep, clear and very cold even in summer. Ammoudi is free to visit and open all year as a harbour, but it is a seasonal place for visitors: the tavernas and boat services run mainly from spring to autumn, and in winter the quay can be almost deserted and battered by westerly winds.

Getting down and back up: the classic route is the long stone stairway from the western end of Oia, roughly three hundred steps that zigzag down the cliff. It takes fifteen to twenty minutes going down and longer coming up, with no shade, so avoid the hottest hours and carry water. You may meet donkeys on the steps; many visitors now choose to walk rather than ride, out of concern for the animals, and the path can be slippery with their droppings, so wear shoes with grip. There is also a road down to the harbour for cars, taxis and some tavernas' shuttles, with a small amount of parking that fills quickly in high season, which is the easier option for anyone who cannot manage the steps.

Swimming and safety: the popular swimming spot is reached on foot around the headland from the harbour, where people swim from the rocks and some jump into the deep water. There are no lifeguards or facilities, the water is deep straight away, and conditions change quickly when the wind is from the west, so only confident swimmers should go in, and only on calm days. Importantly, the coastal footpath from Ammoudi towards Cape Agios Nikolaos has remained closed since the seismic activity of 2025, according to Greek press reports in spring 2026, so follow local signs and do not climb past barriers or under loose rock faces.

How to plan it: combine Ammoudi with an afternoon in Oia. Walk down around two hours before sunset, swim if conditions allow, book an early table at a taverna (reservations are wise in July and August), and either stay for the sunset at sea level, which is quieter than the castle, or walk back up after dark when the steps are cooler. If you plan to visit Thirasia independently, this is where the small local boats leave from; check the schedule at the harbour, as it changes with the season and the weather. In winter, come for the walk and the solitude, but do not count on lunch.
