Reviews Summary
Visitors consistently praise Keri Caves as a must-see on Zakynthos, highlighting the mesmerizing natural beauty of the sea caves and the stunning turquoise waters. The boat trips are a major draw, offering a magical experience of exploration, swimming, and even turtle spotting. While some tours might be busy, the overall consensus is that the caves are well worth the visit for their unique geological formations and breathtaking scenery.
"We visited the Keri Caves by boat and it was one of the highlights of our trip to Zakynthos. The water is unbelievably clear, with shades of deep blue that don’t even look real. We went inside some of the caves and swam through others — such an amazing experience. It felt quiet and peaceful compared to other popular spots on the island. I really recommend renting a small boat or joining a small group tour so you can get closer to the caves and enjoy it at your own pace. Bring a mask for snorkeling, the underwater view is incredible. Totally worth it, a magical place."

"Stunning caves - absolutely breathtaking from the colours of the water to the caves themselves! Our skipper from Ocean Private Cruises took us right in! Super place to visit!"

"We hired a boat and took ourselves there as we were able to be in control of where and when we stopped.
Boat cost €90 for 2 hours from the local guy at the waters edge."
