As others have already said, the caves are superb. It’s €12 per adult, 10 for kids, you buy a ticket at the gate, drive down to the car park, and wait for a boat. It’s about 20 minutes long. We couldn’t book online, and the phone wouldn’t connect, but gave it a shot. We were on a boat after what was at most a twenty minute wait. This was thought in April when tourist numbers are low, so may be much busier over summer. Parking was interesting! When we arrived the car park was full, and cars were parked up the road. Whilst they took up half of it the remainder had a pretty significant trench running along it. This made getting in a bit precarious. We managed, it did subsequently clear, and a small bit got filled in. You might though want to park near the gate and walk down.

The cave was really pretty. The stalactites were beautiful to see. It was also really cool to see them reflecting in the water. Our guide was nice, an excellent skipper as well. The staff however barely speak English and they made us wait quite a bit. Explanations are in Greek only.

Excellent tour of the cave system and definitely worth seeing if you’re in the area. We have been through many caves over the years and this cave was unique and magnificent! So fun to see it all while in a small boat with a small group. Loved it! We simply bought our tickets at the ticket booth this afternoon and didn’t have to wait at all for the tour. Many reviewers had suggested purchasing tickets online in advance, but we didn’t wish to be tied down to a schedule. After you purchase your ticket you can drive further down the hill to park. We parked on the side of the road as the lot at the base was small and quite full and would likely be a difficult place to turn around. Anyway, Diros Caves are highly recommended! Enjoy!

As tickets were sold out online we didnt think we would be able to see the cave on this holiday, but drove down in the afternoon to ask if it was possible to purchase at the desk, and it was! You can only buy the same day as you are to go inside. We got four spots on the last boat of the day, and waited about 10 minutes in total! Beautiful cave system, crystal clear water, and a lovely retreat from the heat. Would have loved to get some information from the boatsman, but there we are. Highly recommend going!

It is very impressive! Really nice. The boat man just spoke in Greek. No translation. I heard another boats were just in silence for all the trip. About 25 minutes. Go early, read another reviews, the lines are crowdy under the sun. The man that sells the tickets is no polite at all.

This was a beautiful site and a boat ride that seem to go on forever. Around each corner was something new and different and our boat. Osman handled the vessel very well. We had no problem with queueing but again we didn’t choose to go when 2000 other people were going in July and August. It’s like anywhere else in Europe you going in peak season you’re going to have to queue
