Do this because

You'll cruise Zante's southern coast by glass-bottom boat, with a chance to spot loggerhead turtles
There's a stop at the Keri Caves and Picines Beach, a white-pebble hideaway reachable only by boat
You'll swim into Eros Cave, explore inside on foot and rejoin the boat at the far side of the cave

What to expect

A laidback island outing unfolds as you hop between some of the prettiest spots along Zante's southern coast. Your day starts with a pick-up from your hotel and a short ride to the little port of Agios Sostis, where a glass-bottom boat is waiting to whisk you off for the day. Once you've grabbed a spot on board and settled in, keep an eye on the water – it's so clear along this stretch that there's a good chance of spotting loggerhead sea turtles gliding by.Your first stop is the Keri Caves, where sunlight bounces off the rock and turns the whole place into a natural light show. From there, the boat glides between the Myzithres Rocks, two towering formations rising straight out of the sea. Then, it's on to Picines Beach, a white-pebble spot only reachable by boat. With fewer crowds and water as blue as a swimming pool, it's a dreamy spot for a dip.The grand finale is the Eros Cave. You'll swim through its small entrance, explore the inside on foot and pop out the far side where the boat circles around to meet you again. After that, it's time for a chilled cruise back to the port. Just so you know, there is also an evening option of this tour, to enjoy the beauty of the south at sunset.

Two things, we didn't know where to go when we got dropped off in the harbour. I do expect to be met where the bus stops by someone with a TUI sign. Captain showed up after a few minutes confusion and was super nice. In the description it says that we should "Du simmar genom den lilla ingången, utforskar insidan till fots och dyker upp på andra sidan där båten cirklar runt för att möta dig igen" This did not happen which was one of the things we wanted to do.

Helaas maar op zoek gegaan naar 1 schildpad daarna niet meer. Het varen langs de kust was prachtig en de mogelijkheden om te zwemmen bij de grot en in de groten was een fantastische ervaring

Boot zat vol dus we moesten op een kleinere boot. Tocht was top maar na de zwemstop moet je op een klein ijzeren trappetje klimmen om op de boot te komen. Door de harde wind gleed ik uit met als gevolg 4 hechtingen in scheenbeen. Het trappetje was dus gevaarlijk. Ook had deze boot geen glasbodem, wel schildpadden gezien en dat was super.

The boat had an extremely small glass bottom not what we were expecting at all. The captain Nokia was fabulous and even with his minimal English he kept us entertained and made sure everyone on the trip had a brilliant time. I don’t think it would have been as good without him

Der manglede information om hvor vi skulle finde båden som vi skulle med da vi ankom til havnen. Det var rent kaos. Selve bådturen var fin. Båden havde dog minimalt glasbund og det var ret skuffende. Kaptajnen osv. var fint og selve turen var fin. Men vi blev ikke hentet til tiden bagefter og det var igen kaos da vi skulle hentes af en bus og tilbage til hotellet.

Only fault would be better instruction when leaving the bus for finding the boat. It was also unclear what would happen at pick up time. Other than that, it was absolutely brilliant.

De excursie op zich is prachtig: Turtle Island, Keri grotten en vaak zwemmen aan prachtige stranden met helder groenblauw water. Wat minder is, was het ophalen en terugbrengen. De chauffeur was heen een kwartier te laat en terug zelfs meer dan 20 minuten, terwijl hij zei dat hij er zou staan. Verder maar twee zeeschildpadden gezien. Wel erg indrukwekkend. De kapitein Petros was geweldig!

Wir kamen an den Hafen und niemand war da und das Boot war nicht gekennzeichnet. Selbst der busfahrer von TUI hat sich beschwert, weil seine Insassen nicht abgeholt wurden. Alle anderen Organisationen hatten so eine Fahne oder irgendetwas was erkennbar gemacht hat, wo man warten soll. Der Rest war super. Überteuert, aber ok.

Trevlig tur., men den motsvarade inte riktigt det som var beskrivet. För det första var beskrivningen av båten missvisande. Glasbottenbåt visade sig vara en båt med två minimala fönster. För det andra gjorde båten avvikelser från den beskrivna rutten utan förklaring. Vi fick inte gå igenom Erosgrottan utan blev istället avsläppta på en ö där vi fick stå och vänta i 40 min på att båten skulle komma tillbaka. Meningslös avslutning på en annars trevlig tur.

De drops op het strand was super geweldig.Het water is kristalhelder. Het spotten van de schildpadden was top. Voor mij mag het minder grotten kijken zijn en meer tijd voor te zwemmen en het strand.

Fantastische boot tocht. Leuke leiding. Indrukwekkende schildpadden. Mooie zwem en snorkel stops in dat heldere blauwe water. Paradijselijke plaatjes met de grotten en langs de kust. Genoten!! En zeker een aanrader, ook door het kleine aantal mensen op de boot.

All the paperwork had been completed when we booked the event. It was only by pure luck - as I don’t usually carry my phone all the time - especially with the liklyhood of of going in the water - but luckily enough I did take it with me and all the relevant information it held on it was duplicated when we boarded, which to me was an unnecessary delay. Otherwise the event was very enjoyable and the crew were very helpful and professional.

De bus die ons ophaalde was veel te vroeg, waardoor mensen in de bus op mij moesten wachten. Daardoor voelde ik me opgejaagd en ongemakkelijk. In de boot was er maar een heel klein stukje glas waar je doorheen kon kijken. Daarnaast deden er veel mensen mee aan het tripje, waardoor het erg druk was op de boot. We zaten erg dicht op elkaar, wat ik niet prettig vond. De omgeving was prachtig en ik was blij dat we twee stops hadden, zodat we even van het overvolle bootje af konden.

Good tour showing you Keri Caves, Turtles, with 2 swim stops and 2 besch stops. The captain was also able to show us several turtles in the waters also. Family run boat with Father, son and daughter. Boat was glass bottom but served no real purpose as no one was actually using it as there wasnt really anything to see. The whole trip is actually a little longer than we expected, take that as you will. We left at 8 and never arrived back at the drop off point until 2.15.

Hele mooie tour. Prachtig uitzicht, stopt af en toe om te zwemmen, heel relaxed. Vonden de”glasboden” wat tegenvallen…..klein(had er n andere voorstelling van) en er was weinig tot niets te zien. Paar kleine visjes en de bodem…..zeer helder water maar niks aan flora en fauna?

Prachtige tocht over de zee naar de kliffen met grotten en kleine strandjes. De schipper was heel vriendelijk en hielp mensen indien dat nodig was. De duur van de tocht was wel lang zonder de mogelijkheid om naar de toilet te gaan. Ook was de glazen bodem maar een klein deel van de boot. 40 minuten aan land, om iets te eten of drinken vonden wij ook te lang, daar het nog maar 10 minuten varen was naar de eindbestemming.

Zeer mooie tocht, prachtige rotspartijen met azuurblauwe zee. Onderweg zeeschildpadden gezien. Kapitein nam ruim de tijd voor ons als gast om dingen goed te kunnen bekijken en filmen/fotograferen. Een mooi stop op turtle island gemaakt, waar we ruim de tijd kregen om aan het strand wat te eten en drinken. Kortom een prachtige ervaring!!
