Kokkinokastro Beach Alonissos lies on the eastern coast of the island. It stretches about 7 kilometers northeast of Patitiri, the island’s main port. As visitors approach, they quickly notice the dramatic red cliffs rising above the shore. These striking colors give the beach its name—“Kokkinokastro” means “Red Castle.”

The beach features a mix of golden sand and yellow pebbles. As a result, the shoreline feels both soft and textured underfoot. The sea becomes deep only a few meters from the shore. Therefore, swimmers can enjoy refreshing, cool waters. 

Reaching Kokkinokastro is simple. Travelers can drive or rent a scooter from Patitiri. After parking, a short path leads down to the beach. The trail remains clear and manageable, even for families with children. Consequently, the beach attracts both locals and tourists.

Kokkinokastro offers some basic comforts. Visitors can rent umbrellas and sunbeds during the summer months. Additionally, a small wooden beach bar provides cold drinks and snacks. However, no restrooms or changing rooms exist. 

Beyond natural beauty, the beach holds historical value. Ancient stone walls from the prehistoric town of Ikos still stand nearby. Moreover, the small islet Kokkinonisi, just offshore, contains early human artifacts. Archaeologists have discovered tools and pottery from the Paleolithic period there. These findings show that people lived in the area over 9,000 years ago.

Kokkinokastro looks especially beautiful during early morning or late afternoon. The sun highlights the red cliffs, casting a warm glow over the sea. Photographers and nature lovers often choose these hours to enjoy the peaceful setting.

In conclusion, Kokkinokastro Beach Alonissos combines natural wonder, clear waters, and deep history. With easy access and nearby attractions, the beach offers both relaxation and adventure.
