    Things to do in Santorini in August

    Oia Village

    Santorini is famed for its incredible sunsets and one of the best places to see them is in Oia.

However you decide to watch the sunset, make sure you bring a camera so you can capture the image forever.

    Cool off from the summer sun by spending a day at the Santorini Water Park.
