Driving in Santorini can be challenging due to narrow, winding roads, steep inclines, and intense traffic during peak summer months. Many roads were originally built for donkeys and are barely wide enough for two small cars to pass, often requiring one driver to pull over or reverse. High-traffic areas like Fira and Oia suffer from severe congestion and extremely limited parking. Furthermore, the island is shared by large tour buses, local "Safari" trucks, and a high volume of inexperienced tourists on ATVs and scooters, which can lead to unpredictable traffic patterns. If you are a confident driver and opt for a small, manual or automatic car, it is manageable and offers great freedom to visit remote beaches. However, if you are uncomfortable with cliffside driving or tight spaces, utilizing the local "KTEL" bus system or private transfers is a much more relaxing way to experience the island.
