Caves of Diros

Absolutely amazing. The cave colors were breathtaking. The trip began with a walk to the cave entrance. We were provided with life jackets and entered a row boat. After the boat reached its destination, we continued on foot. The trip takes 15 min end to end. However, once the foot portion begins, you can take your time. We weren't rushed. The beach surrounding the caves is also beautiful. The water was calm and warm. A few clarifications, arrive early to get your tickets. Even though the cave ticket booth opens at 9 a.m., people start arriving around 8:30. Also, the green light for ticket sales begins once the ship captains confirm the water level. As such, I don't recommend buying your ticket earlier because what you buy may not be tide appropriate. Once you buy your tickets, you can drive to the cave's entrance. There is a parking lot there, as well as a snack bar and washrooms.

Very beautiful and above all large stalactite cave. It was very interesting to walk through it. Stalagmites and stalagmites in all shapes and sizes. The cave is well lit. At the end of the path you can see the underground landing stage for the boats. The combined tour, which starts with the boat trip and then turns into the land tour, is certainly much more interesting and recommended. Unfortunately, we were unable to do this on this day as the boats were not available. Unfortunately, the information was not available on the website and online booking was also not possible. Therefore one star deduction. There are free parking spaces both at the top at the ticket store and a few below directly at the cave. Another little tip, on the opposite side is a nice little beach, 7 minutes away by car, highly recommended. Not to be confused with the small beach right next to the stalactite cave.

Paid 44€ for 2 adults and 2 kids. For the past few months they have decided to only show a tiny portion of the lake part of the cave, the one you visit with the boat. Used to be a 30 minute ride with the canoe, now you get 5 minutes, skip the beauty of the long ride, and only do almost like a straight trip from the boarding area to the disembarking area. Then approx 200-300m of a walking path follows. There is a basic cafe (think 50s without the glamor) and no gift shop. Employees sitting around doing not much, besides complaining about the government, if you ask about the closure of the long boat ride. (lack of staff they claim). The cave is spectacular, the experience on the little canoe is exciting / 5 minutes worth of excitement. Like others have said, if you are close by, and you can afford it, go. Don’t drive from Athens 3 hours for this. Wait for/if when the full experience opens again.

We visited the Diros Caves on our way from Corinth to the Mani Peninsula in the Peloponnese. The drive to the site was beautiful, especially the descent from the highway. We waited about half an hour before starting the tour, which we did with a guide—essentially a private one, as it was just us and our three children. The guide’s explanations were engaging and full of amusing associations, finding shapes and characters in every stalactite, which made the experience both fun and entertaining. The kids really enjoyed it, and so did we. It’s a great stop along the way and a pleasant family experience. The cost for two adults and three children was about 20 euros—very reasonable. The tour lasted about an hour.

Often mentioned but disappointing. The visit is very short and purely touristic: just a few minutes by boat, with fast circuits clearly designed to avoid queues and maximize turnover. Though presented as ancient and fragile, boatmen push directly against the walls (strange), while the final 10-minute walking path is full of signs telling visitors not to touch anything. In the end: a rushed 20-minute visit for €68, with little real value. Far better to enjoy a peaceful lunch by the water in Geroliménas!

Lovely Underground Experience at the Caves of Diros The Caves of Diros offer a wonderful and quick underground adventure through a beautifully lit cavern system. The highlight is a 300-metre guided boat ride, gliding quietly through the cool, still waters—truly magical. After the boat ride, there’s a short walking section that lets you explore even more of the cave’s natural beauty. It’s not a long tour, but it’s definitely a memorable and very enjoyable experience. Highly recommended if you’re in the area!

Do NOT go at this time. They only offer the “short version” boat ride which (according to the video I took) lasted literally 7 mins. 22seconds!!!! I posted 2 of the 3 videos…..Then you get off the boat and walk on your own thru the cave for an additional 10 mins to the exit. No guide, no staff, no one! You just wander on your own…. It was a great letdown, considering it is the largest water cave in the world (extending over 17 km)!

Unfortunately the long trip is not available in this period, the ticket office and the website are clear about it. The boat driver was explaining the tour only in Greek, no English so we didn't get any information about the caves, just watching and taking pictures. Not the best esperience for foreign tourists but the caves are cool.
