This might just be the one mentioned in the introduction - there are two beaches here; some reports would be welcome! Also for:

This seems highly attractive! if you can find the way there.

"I think Aghios Ioannis beach is the same as Monasteri beach as the monastery by the beach is [dedicated] to Ioannis. Happy to be corrected" says The Barefoot Doctor in 2017. Seems entirely likely says the Admin: Thank You!

2019 May: We (Bored Pacianga & girlfriend) visited these two beaches and found both written on Google Maps "Tripiti". Both are very easy to access by car; the westernmost, the first of the two above, is a sandy beach, with a stones label indicating "nude beach" on the sand. We went there twice; the first afternoon was almost deserted, just 4 people, we included, all naked. The second, a Sunday morning, was full of families dedicated to a glorious barbecue. Obviously no nudity, so we went to the other "Tripiti" beach (the second of the above, 7 minutes by car to the east; we found there also grilling people, 2 young couples, but naked, so we stopped there and enjoyed the day. Just remember to wear long trousers and not flip-flop for the last 50m.

2021 July: In a report we went to Tripiti 2 Beach, 7mn west from Tripiti beach. After parking 500m from the beach, we walked to the beach which was not crowded but full of families and only textiles. After a few hours, we saw one woman going to swim, naked in the middle of textiles, followed one hour after by one man. They were the only two naked persons on the beach (almost 30/35 persons around). We enjoyed the day and finished going naked after 7:00PM, when there was only 7 persons (us, two young couple and one guy) left .
