For four weeks in Summer 2021, I was able to take a class on the Anthropology of Food in Greece, taught by Aimee Placas (who is amazing!). The course, and Greece in general was amazing. I learned so much about food, traditions, culture, etc - and ate my way through 7 Greek islands as well (yum!). I'm missing the experience and the people I met along the way already.
I highly recommend taking the ferries from Athens (Pireaus) to islands like Aegina, Naxos, Poros, Paros, etc. Ikaria is another favorite - but fly there!
