Are beaches in Santorini free?

Yes, all beaches are public. You only pay if you choose to rent a sunbed and umbrella from a private vendor, which usually costs $10–$20.

Can I visit in August on a budget?

It is very difficult. Accommodation prices double or triple in August, and the island is extremely crowded, making budget transport harder.

How to Visit Santorini on a Budget

Skip staying in Oia or Fira to save 60% on accommodation and use the local KTEL bus system instead of taxis. Eat at local souvlaki shops and carry a reusable water bottle to keep daily costs under $120.

Book accommodation in Karterados or Perissa. Avoid the cliffside towns of Oia and Fira. Staying inland in Karterados or on the black sand beach of Perissa costs roughly $60–$80 per night compared to $200+ in the caldera view zones.
Use the KTEL bus network. The bus terminal is in Fira. Tickets cost between $1.60 and $2.50 per trip. Buy them in cash directly from the conductor on the bus. Avoid renting ATVs, which cost $40–$60 per day plus fuel.
Eat at local grill houses. Look for 'gyros' or 'souvlaki' shops where locals eat. A pita wrap will cost you about $4.50–$6.00. Avoid any restaurant with a view of the caldera, as they often charge a premium for the location.
Hike the caldera rim. The hike from Fira to Oia is free, takes 3 hours, and offers the same views people pay hundreds of dollars for on sunset cruises. Bring 2 liters of water and wear sneakers.
