Uncovering Rhenia, the Secret Island Next to Mykonos

Mykonos enchants at first glance not just for its iconic windmills, the colorful houses of Little Venice in Mykonos Town, and its vibrant nightlife. Its beaches, such as Paradise, Super Paradise, Psarou, and Elia, are true havens for sea lovers, water sports enthusiasts, and music fans. But are there places on the island for those seeking something more intimate and authentic, far from the crowds? Absolutely. One such place is the island of Rhenia.

Rhenia: The Wild Face of the Cyclades

Located less than 2 km west of Delos and about 6 km from Mykonos, Rhenia (also known as Rineia or Rinia) is an uninhabited island in stark contrast to the lively energy of Mykonos. Here, you’ll find peace, untouched nature, and complete seclusion. It’s the perfect place to disconnect and enjoy the sea in solitude or with just a few lucky companions.

The island covers around 14 square kilometers and has no permanent settlements. There are no hotels, restaurants, or bars. What you will find are crystal-clear emerald waters, hills dotted with ancient ruins, and often total silence—interrupted only by the sound of waves and wind.

Its rugged coastline features hidden bays and sheltered coves, ideal for anchoring private boats and swimming in complete tranquility. The beaches have no official names and are usually referred to based on their location.

Rhenia is a protected area, and its sea is incredibly clear—perfect for snorkeling.

The Ancient Link Between Rhenia and Delos

Rhenia has an ancient history closely tied to that of nearby Delos, one of Greece’s most important archaeological sites. In antiquity, Delos was considered a sacred island, believed to be the birthplace of Apollo and Artemis according to Greek mythology. To maintain the island’s “purity,” from the 6th century BC onward, it was forbidden to be born or die there. For this reason, people were transferred to Rhenia to give birth or to die. The island thus became a functional extension of Delos, hosting necropolises, minor temples, and shelters.

During archaeological excavations conducted in the 20th century, numerous tombs and artifacts were discovered on the island, some of which are now preserved in the archaeological museums of Mykonos and Delos.

Can You Visit Rhenia?

Yes, you can visit Rhenia—but only by boat, perhaps as part of a Mykonos boat tour. There are no regular ferry services to the island, unlike other destinations. However, you can join one of the many daily boat excursions departing from Mykonos, or rent a private boat, with or without a skipper.

Many Delos tours include a stop at Rhenia. Some excursions also offer kayaking, paddle boarding, or snorkeling equipment.

Since Rhenia has no tourist facilities, it’s important to come well-prepared. Bring water, food, sunscreen, and water shoes if you plan to explore the rocky areas. Remember, this is a protected area, so don’t leave any trash behind or take stones or artifacts with you. Respect the environment to preserve the beauty of this extraordinary island.
