Agios Stefanos Beach is one of the most picturesque beaches on Kos, combining natural beauty with fascinating history.

The crystal-clear waters are ideal for swimming and snorkeling, while the small islet of Kastri, just offshore, provides a stunning backdrop for photos. Visitors can even swim or take a paddleboard across to the islet and explore its charming white chapel.

9 months agoAncient ruins of Agios Stefanos by the Aegean Sea, where early Christian basilicas once stood. Today, the site offers a stunning view of the Milky Way under clear night skies. Captured on July 13, 2025

10 months agoVery nice beach next to old ruins. Good place for snorkelling around the ruins where you can see a lot of fish. Beach on the right side had the view on the island but it’s crowded, small places between the sundbeds and they charge you 25 euros for sunbeds witch is ridiculous.. I recommend you to go to the beach on the left side of the ruins where the beach si much better and sunbeds cost ,,only,, 15 euros - (saved 10 euros - better beach - less people). If you want to go there without people, try to stop by around 18:00 to get this view.

10 months agoThe best sea in Kos. Sea was so clean and fresh. Also it was great to swim antic beach. You would want to swim to Kastri if you are good at swimming(recommended. So natural place to swim so there is no beach club and shower.

8 months agoA beautiful beach where history and nature meet. The water is shallow and clear. Of course, this can vary depending on the weather. It's far from the island's center, so you'll need a car or motorcycle-like vehicle. There's parking, but since it's a crowded and popular beach, you might have trouble finding a spot. There's a cafeteria-like kiosk where you can find your essentials. You can rent a sunbed or sit on a stone on the beach and enjoy the sea. As I said, it's a bit of a journey, almost the tip of the island, but it's worth it. It's better to come early. It gets very crowded after that.

9 months agoThe beach itself is amazing and truly unique – swimming right next to 3,000-year-old Greek ruins is an unforgettable experience. The water can be a little cold, but it’s refreshing, and the beach is very child-friendly, which makes it great for families. There are a few challenges though: parking is quite difficult to find, and the free part of the beach gets very crowded. If you don’t arrive early, it’s hard to get a good spot. The other half of the beach belongs to a private hotel, so access is limited. Also, toilets are an issue and could be improved. Overall, despite the practical inconveniences, it’s absolutely worth visiting for the history, the scenery, and the atmosphere.
