This is a very long beach with several coves located south of Milos beach. If you want to be alone in your own cove this might be your choice. The sand is rather coarse and there is a lot of shingle. The beach can be reached from both ends. To reach the northern end turn off from the way between Aghios Nikitas and Kalamitsi. The signpost reads "Kathisma beach". The main beach is textile with a taverna at each end. Park at the southern taverna (Akroyiali), where you will be able to shower on your return, walk past a low rocky headland and you reach the nudist part. It is best to walk along the shore line as the path at the back of the beach is crumbling away in parts and is becoming dangerous.

Starting at this restaurant and walking southwards, the beach becomes naturist surprisingly quickly; after perhaps 150 metres, there's a little beach (~200m) and walking here is difficult because you sink down in the soft sand and pebbles. Then, after some big rocks, the beach opens up to a practically deserted naturist beach. Walking here is easier.

2015 August: Kathisma is probably the best Lefkas beach, with the same (or better) turquoise colour than Egremni. Not the main section - with a lot of bars ect. - but the nudist section. The best way to go there is the road from Kalamitsi village to Kavalikefta. 1km before Kavalikefta, facing a sign "to Avali beach-bar", follow this road, don't stop at Avali after 500m (clean but totally textile beach), pass the next pebble deserted beach and after 200-300m you will see another beach, pebble and sandy. Good beach but the best place is the beach at the end of the road.

This is Kathisma beach. The first half, about 80m, is dressed, the second totally nude. We met there up to 15 other nudists (the textiles at the first section are far more but they accept nudity). Almost all nudist were couples, except a single man. We found the beach very nice and clean. The sandy bottom is also nice - no sandals needed. We stayed 7 hours there, so bring your own water and food. Bring also a sun umbrella because no shade there (no trees).

It seems that a discreet and civilized sexual activity is accepted, because no kids were there: As I noticed, all couples went inside the water for kisses, hugs and penetrations. I confess, that seeing the habit, I did the same with my wife and she told me it was perfect. Go there, stay au naturel and keep the beach clean!

2016 May / June: The third stretch of beach is still clothing optional, about 50% nude. A camper was parked there, the owners stripped in the afternoon to take a swim and stayed nude the rest of the day. There is construction work going on further north, but we doubt it threatens the nudity at the beach. No creepy (masturbating) single men seen during several visits, great decent nude beach. Late June: The second and especially third stretch of beach is clothing optional, about 75 to 90% nude. Somewhere between 20-30 people. Nearly 10 couples and a few single men. Some aged between 30 and 40 years. Many people coming from the main beach, swim naked and after some time they are returning.

September: The road which gives the southern approach via Kalamitsi was narrow and in such bad condition that some people were abandoning their cars before the Avali turn-off and proceeding on foot. I turned round and went to the beach via the northern approach (signposted Kathisma beach) but when I reached the third beach (the only nudist part) it was clear that at least some cars had got through to the end of the road via the southern approach.

2019: Visited the nude (southern) part of Kathisma (here) 3 times this summer. To find it you park at the southern end of the road and then walk on the beach and past the rocks. Beyond that point, everyone is nude and you can easily find a spot there. There may be occasional textiles walking by from the main beach, but no creepy single gawkers here. April: The northern end and much of Kathisma beach is backed by tavernas and is 100% textile. However, nudism is accepted beyond the rocks at the southern end 38°46'20.7"N 20°35'54.7"E. When we visited at the end of April there was just one other m/f naturist couple and a small group of textiles at the southmost end.

Kathisma is a gently sloping gritty sand and pebble beach backed by high ground. The sand and small pebbles shelve gently for a few metres below the waterline but then there is a small drop onto larger smooth rocks and boulders. These can make entering and, even more so, exitting the water difficult, particularly if there is an onshore breeze whipping up waves. When we were there the waves were churning up the sand so water clarity was poor and not great for swimming but probably OK in calmer conditions.

2021 August: Kavafis reporting says "I realized that the beach currently referred as the third bay of Kathisma and Gaidaros are actually the same place." Bear this in mind when reading what follows….
This third section of the beach is the best for swimming (more sand). The road at the back of this section of beach has collapsed. Beyond this it continues and provides access as small vehicles arrived from the other direction, which makes access with a bit of luggage much easier. It is quite a drive from the main entrance, but it saves you a long walk and climb along the beach and over the rocks.
Reports say that the second and third beaches are totally nude and almost completely deserted. The first beach (with the taverns) is fully textile.
