Post w Lake Tekapo, Canterbury Region, New Zealand

Hello everyone, I just arrived in Athens for my Erasmus stay but brefore university starts and the waters are warm, I would like to go explore. I would love to use the warm weather to go out to some beaches, if not island and am looking for some recommendations :) Ideally it would be with nice beaches, (I like scuba diving but do not have equipment- just a masque),and places for hiking, running, etc. I would like to avoid party areas and if possible crowded areas, too ;) I brought a tent and sleeping bag and could do some overnight trekking as well. (I don't have a car.)

If you have any recommendations please let me know! :)

And if you happen to know someone who is renting a studio/flat please also let me know ;)

Thanks a lot ! Kind regards, Katharina.
