We visited Agios Stefanos beach twice in Oct 2023 despite staying near Kos town we liked it enough that we visited a second time. This was my favourite beach on Kos. The ruins are worth seeing and the beach itself is clean and easy to access. There are plenty of sunbeds on the beach but there is also plenty of clear sand if you don't want to pay for a sunbed. Kastri Islet is interesting and easy to swim to although I couldn't see a way to reach the top of the highest part of the rocky outcrop (and I suspect there were birds up there that are best left undisturbed). On our second visit we did some snorkelling and found there was a reasonable amount to see. The water was calm and clear and a good temperature.

This is a lovely beach. You can use the facilities next door. The food from there was excellent. Large portions & good price. For €10.00 you get 2 sunbeds & an umbrella. Very friendly people who run both the sunbeds & the cafe. Water sports are right next to the sunbeds. No problem with them at all.

It is very clean and easy to park and the water is crystal clear. There is a takeaway van and a nice taverna on the beach. There are 2 places to hire umbrella - the one by the taverna is cheaper at 10 euros foe 2 beds and an umbrella

It was busy but I found parking close to the beach. The beach is safe and I left my towel with car keys there with no issues. Snorkeling is safe for those who are good swimmers to the islet Kastri. Make sure to wear shoes. It was a steep cliff to climb up to the church, but I made it without help & was able to ring the bell! I jumped in the water where the pedal boats & kayaks pull up and it was much easier than going down the cliff to the water. The ruins on the beach are interesting! Enjoy

We went to the beach east of the old ruins of Agios Stefanos. An umbrella plus two sunbeds cost 15€ which is way more than in other places. The beach itself is really nice and the water slightly cool. You can Walk in the water for about 50m before you really need to start swimming. We really enjoyed the stay there.

The beach was sandy and the sea warm. There were relics of a monastery on the beach. You can cross to Kastri Island a short distance away by pedalo or sea kayak. We decided to swim across to the island. It had a typical Greek chapel and short walks to explore. We tried rock jumping before swimming back. A must visit destination.

Nice view of Kastri Island, plus there are the ruins of a monastery to explore. Sea is clear, bit pebbly so bring some swim shoes. We were staying in the Ikos hotel, so worth going down to this beach, but I wouldn’t bother travelling any distance to it.
