Kastani Beach is one of the most famous beaches on Skopelos Island. It lies on the western coast, about 15 kilometers from Skopelos Town. Surrounded by lush pine forests, it offers a stunning mix of turquoise waters and soft white sand.

The beach became widely known after appearing in the movie Mamma Mia!. Its natural beauty and crystal-clear waters attract visitors from around the world. Despite its fame, Kastani maintains a relaxing and unspoiled atmosphere. The sand is fine, and the seabed is mostly sandy, making swimming enjoyable. The waters are shallow near the shore, perfect for families and casual swimmers. 

A beach bar operates on-site, offering sunbeds, umbrellas, and refreshments. Visitors enjoy cocktails, snacks, and music while relaxing by the sea. The organized area blends well with the natural surroundings, keeping the beach’s charm intact.

Kastani Beach is easily accessible by car, as well as by bus. A well-maintained road leads directly to a parking area near the shore. The short walk from the parking lot reveals breathtaking views of the bay.

Water sports and activities available at the neighboring Milia Beach add to the fun. Visitors can try paddleboarding, snorkeling, and beach volleyball. The clear waters allow for great underwater visibility, making snorkeling a popular choice.

Sunsets at Kastani Beach are unforgettable. The sun dips behind the horizon, casting golden hues over the sea and cliffs. Many visitors stay late to enjoy the peaceful evening atmosphere. Despite its popularity, the beach rarely feels overcrowded. Those seeking more privacy can explore nearby small coves.
