Kalafatis Beach is a popular spot on the eastern side of Mykonos, known for its family-friendly vibe and great water sports scene, especially windsurfing. It's a bit less developed than some of the more touristy beaches, but still has a few hotels and restaurants nearby. The beach itself has some rocks near the shore, but once you're past them, it's perfect for swimming. Plus, if you fancy a change of scenery, the smaller Agia Anna Beach is just a short stroll away.
