Things to do
Santorini is internationally renowned for its sunsets and the island’s lighthouse is one of the best places from which to enjoy them. You can drive up to this site and park a short walk away or cycle straight up to it, depending on how energetic you’re feeling. The lighthouse – known locally as ‘Faro’ – marks the end of the island and is surrounded by volcanic rock and pine trees, making for a very picturesque setting. If you arrive an hour or so before sunset, you’ll have the opportunity to snap a few photos whilst the sea is bright blue before the sun begins to set and everything gets drowned in orange and red hues.
The Monastery of Profitis Ilias is one of the most-visited churches on the island, making it a must during your holiday. Located in Pyrgos, the simple stone church features traditional Greek-style architecture and offers fantastic views of the island below, so make sure you bring your camera with you. You’ll definitely need a car to visit the site – the Monastery of Profitis Ilias is located on a very tall hill – and unfortunately, visitors aren’t allowed inside the monastery, so you’ll only be able to enjoy it from the outside.
