If you are traveling on a budget, Santorini may not be the most affordable destination. During peak season (June to August), prices tend to skyrocket due to high demand. However, visiting in shoulder season (April-May or September-October) can result in significant savings as prices drop by up to 50%. Additionally, staying in accommodations outside of popular areas like Oia or Fira can also save you money while still allowing you to enjoy the island's beauty.
