Oia, Santorini, is famed for its stunning sunsets, whitewashed buildings, and breathtaking caldera views. The village is mostly pedestrianized, with some steep slopes and stairs, which can pose accessibility challenges. Exploring independently allows flexibility, but guided tours offer historical context and local insights. The peak season is from June to September, with milder weather and fewer crowds during the shoulder seasons (April-May & October). Expect higher prices during peak season, and a visit typically lasts a full day to fully appreciate the views, shops, and restaurants. Consider booking accommodations and tours in advance, especially if traveling during peak season. Be aware that the paths are crowded, particularly during sunset.
