If there was an award for the most scenic stretch of pathway in Europe, Santorini’s crater hike would be the one to beat. The 10-kilometre walkway along the Greek island’s volcanic caldera links a series of whitewashed villages – Fira, Firostefani, Imerovigli, Oia – and offers stunning sea views all the way along.
The catch? If you come any time between May and September, you will find that hundreds of your fellow travellers have had exactly the same idea and are thronging the path, turning what should be a highlight into an ordeal.
