Apella, Kyra Panagia and Achata have almost the same roads. You turn right from the main road, and there is a long, narrow, curvy road all the way down. But you will love Achata when you get there. We found the spot and parked our car, and the beach wasn't that crowded. It has natural shade from a big tree so you can stay there or rent an umbrella, or put your own umbrella. The beach is rocky, the water is cold, but not too much. It gets deep very soon, but it is good beach if you want to swim and climb on the rocks. Water is crystal clean and there is no wind in this beach, which is rare on Karpathos. Beach is beautiful, and you should visit it.
