Tosha recommends you visit The Castle of Agios Nikolaos in Oia! She loves everything mythological and medieval architecture.
Want to watch Mamma Mia and eat a fabulous meal on the waterfront? This is THE PLACE!
Once you walk the 300 steps to get here, go to the beach, dine at a seafood restaurant, or even go cliff jumping! Don't forget water shoes and a water bottle! If you don't want to walk back up, it's roughly $10 euros for a taxi back to the top.
Great place for a beach day! Keep in mind, most beaches on Santorini have small pebbles, not sand.
One of the best souvenirs you can get!
