There is a little beach off the small fishing village of Diafani that you could swim in, but for a more secluded experience head to nearby Vananta (pronounced Vananda). Better done by boat than road from Pigadia.
Not far from the airport, this sandy shallow beach is perfect for families and not too busy. However you need to get your own umbrellas.
Here's a decent organized beach with some umbrellas that's not crowded, lying serenely a few minutes away from the airport on the way to Pigadia. The name means "Well of Christ".
The name of this beach means 'Clay River', boasting white sand, shallow waters and big waves that are great for surfing. A beach canteen onsite comes in handy.
Considered one of the nicest beaches on the island with stunning waters. Easier to access by boat than by road. Not much else apart from the gorgeous beach though.
These three sandy beaches near Pigadia, the capital of Karpathos, offer clean waters, different watersports, good food and sea-side restaurants. They are most popular and happening, so not ideal for those seeking privacy.
A quiet and pretty beach some 13 km from the capital. Sandy and pebbly with gorgeous waters, surrounded by mountains and greenery. There's a small 'taverna' for food.
The beach of Agios Nikolaos near the village of Spoa has won accolades for its clean waters. There are umbrellas, beach chairs, and a little restaurant, all in a serene environment.
Here's a well-organized beach near the big village of Arkasa on the western side of the island, 15 km north of Pigadia. White sand, shallow waters and delicious little restaurants (tavernas) serving seafood and local cuisine.
One of the most gorgeous pebbly beaches on the island, this beach is surrounded by rocky hills and shrubs. Mostly deserted, great if you have a boat to explore. Access also by dirt road.
