We were able to purchase tickets online from the USA and they were honored (We'd also been told that this wasn't possible). We expected long lines because it was July, so we arrived early, and we did not have to wait long. We were placed in the "English speaking" line, and our guide spoke serviceable English, and was polite. The caves were certainly worth visiting, just as remarkable as described!

Arrived 11am and queued at the first gate for tickets. Only the long tour was available. Limited parking at next area but there is a small cafe and we waited about 10-20mins to be called for a boat. Must be chaos when the coaches arrive. Given a huge buoyancy aids and told to get in the boat by guide based on weight distribution. I was very nervous about the small spaces but actually you have no time to think about it as you're moving fast all the time from cave to cave . The issue is the ridiculously bulky buoyancy aid as you are told regularly to bend down but you can't wearing it. That was my biggest criticism. It's practically strangles you. Our guide was OK and told us about the cave. Not an easy job as I can imagine people don't listen to the instructions and it could mean someone hits their head or off balances the boat by turning round . But it's all good if everyone does as he says. You Almost travel a bit too fast and you can't see everything as you can't turn much and have people say infront off you off course. My son was sat at the front, so he got some great photos. Was a nice thing to do, but could be better if they sorted the buoyancy aids out so people can duck better.

The caves are absolutely stunning- I have visited many caves over the years and these are absolutely one of the best. The formations are incredible and world class. The boatman however was rude and aggressive. He acted and spoke as though he was drunk. He shouted and sang loudly and out of tune, it seemed almost revelling in the discomfort he was causing. He punted as fast as he could to get round. It spoilt the serene beauty of this place. Advice to the management- get a grip on your boatmen or change them!

Decided on a whim whilst visiting Areopolis to go to caves. Parked up on the hill and purchased tickets. Then drove the car down to the entrance. We were planning just doing the walking part not the boat. After queuing up for what seemed like an eternity waiting for half a dozen locals to exchange pleasantries with the ticket lady we were then told that the land only walk wasn't an option and the boat and land tour was only available. We agreed and got 3 tickets at €17 each. Ushered down to the boats with a life jacket on we then got on the small paddle boat seating about 8 persons. We set off with the tour guide at the back pushing us along. Not one explanation of what we were seeing the whole time time. All in Greek for the three Greeks on board with 5 British. So apart from ducking out heads and not daring to move for fear of unbalancing the weight of the vessel it really wasnt worth it. I felt like a little history along the way would of made it appreciated. The cave itself was stunning. So at the end of what seemed like a lifetime we got off and walked 300m to the exit. A short walk and we were back on the hill at the car.

We enjoyed the tour of the cave, it's an amazing cave to explore, first by boat and then on foot. There are a few things that could be improved; it was a bit unprofessionally run but still a worthwhile experience highly recommended. There is no good system of taking names to ensure first come first served. Once in the boats, the narration is in Greek so for non-Greek speakers it's not helpful. The guides come across as rude, but i think it's their broken English and the fact that they probably have to repeat warnings and make sure the boats don't tip over all day long. Once the boat tour ends, you walk through the rest of the cave and have an opportunity to take more photos as you exit. The scenery as you exit the case is also amazing. Highly recommended!

The caves are amazing, but the people who work there were not friendly and didn't convince us that the water level truly prevented the longer trip. Considering the high number of visitors per day and the small number of boaters, I wonder if the high water level in the caves was just an excuse. Shorter trips might allow more visitors to see the caves, which would mean more tickets sold and more money with less effort by the boaters each day. The souvenir shop at the caves was closed, and the surrounding area was full of debris and building remnants.

Απίστευτο μέρος! Incredible place that travels you back in time. An amazing geological miracle. A must for your trip. Be aware though that usually in the summer months only the short trip is available. Still amazing.
