The Greek islands always have a way to leave you breathless. Santorini, being one of the most famous islands, is truly magnificent. It's an island that attracts many tourists, but once you've been you truly understand why.
The cheapest way there is usually from Athens. I paid 20€ round trip for my ticket on a low cost airline. However, depending on the season and when you buy your ticket, they are usually higher than this. Another option is to take a ferry from Athens or another island.
Getting around is quite easy. For less than 2€ you can take the local bus to Fira or other cities around the island. Taxis are very expensive. Like many, I opted to rent a quad for the day. For 25€ including insurance I had my own wheels. Reasonable priced lodging is relatively easy to find and numerous depending on the season. The beginning of November was perfect for me because there were less tourists than at the peak of summer, the weather was still sunny and warm, along with lower prices. On a tight budget, Gyros for 2.50€ quickly become your favorite meal.
Oia is the epic village that's best to be visited right before sunset and then find your perfect spot to enjoy the spectacular sunset show. Fira, Pyrgos, and Red Beach were my other favorites to check out, each with their own charm and not to be missed!
