Just a few nautical miles north of Heraklion lies Dia Island — a small, uninhabited jewel in the Aegean Sea that blends natural beauty, rich mythology, and ecological significance. Often overlooked by mainstream tourism, Dia offers one of the most serene and authentic day trip experiences in Crete.

The History and Mythology of Dia Island

According to Greek mythology, Dia Island was created by Zeus to protect Crete from pirates and invaders. Its name even comes from “Dias,” another name for Zeus. Ancient Minoans are believed to have used the island as a strategic outpost, and archaeological findings suggest it may have been home to a harbor settlement in the past.

Today, Dia remains uninhabited, preserving its mystique and raw charm. You won’t find shops, hotels, or crowds here — only nature, sea, and stories whispered by the wind.

A Protected Natural Reserve

Dia Island is part of the Natura 2000 protected area network due to its biodiversity and important wildlife habitats. The island is home to endangered species of birds, rare flora, and the endangered Cretan wild goat (kri-kri), as well as a rich marine ecosystem. Its rocky coastlines, sea caves, and pristine coves make it a sanctuary for snorkelers, nature lovers, and adventurers alike.

A Top Destination for Sailing and Day Cruises

Thanks to its close proximity to Heraklion (just 7 nautical miles away), Dia Island is a top destination for sailing tours and private boat cruises. Visitors can enjoy swimming in crystal-clear waters, exploring hidden beaches, and relaxing under the Mediterranean sun. Popular activities around Dia include snorkeling, paddle boarding (SUP), and fishing.

How to Get There

The only way to reach Dia Island is by boat, making it a perfect destination for those seeking an exclusive and off-the-beaten-path experience in Crete. Most tours depart from the Heraklion port and include a scenic sailing journey along the Cretan coastline.
