Tucked just off the coast of the cosmopolitan Mykonos lies a tranquil and often-overlooked paradise: Rhenia Island. Known for its untouched beaches, crystal-clear waters, and rich ancient history, Rhenia offers a stark contrast to the lively party scene of its famous neighbor. If you’re seeking a day of peace, nature, and a dash of Greek mythology, this hidden gem in the Aegean Sea is well worth a visit. Its serene beauty and quiet shores provide a glimpse into the more traditional and untouched side of the Cyclades. And far removed from tourist crowds and noisy clubs. It’s an ideal place for travelers craving a true escape, where the main soundtrack is the gentle lapping of waves, and the views stretch endlessly in every direction.
Where is Rhenia Island?
Rhenia Island, also spelled Rinia or Rhenea, sits just west of Delos and a short boat ride from Mykonos. Though uninhabited today, Rhenia was once part of the sacred center of ancient Greece, paired spiritually and culturally with the nearby island of Delos. Today, it’s a favorite day-trip destination for those looking to escape the crowds and immerse themselves in nature. The island remains protected, and because it is undeveloped, visitors can experience an authentic taste of the Cycladic wilderness. It’s a raw and windswept place where goats outnumber humans, and sandy trails crisscross sun-bleached hills.
A Historical Treasure in the Aegean
While Rhenia may seem like a peaceful paradise now, it has a surprisingly rich and sacred past. In ancient times, it served as a burial ground for Delos, which was considered too holy for the dead. The island is dotted with archaeological remnants, including ancient tombs and ruins that whisper stories from thousands of years ago. Though the island isn’t officially open for exploration like Delos, its silent history adds a mysterious and powerful aura to the landscape. It’s a place where you can reflect, walk softly among forgotten stones. And feel the weight of time settling gently on the land. The ancient sanctity of Rhenia adds a layer of spiritual allure that deepens the experience for thoughtful travelers.
How to Get There
The only way to reach Rhenia is by boat, and there are plenty of options from Mykonos. Many guided tours include both Delos and Rhenia in a single day trip, allowing you to soak up ancient history and then relax on Rhenia’s pristine beaches. You can also charter a private sailboat or join a catamaran cruise that includes stops for swimming, snorkeling, and lunch onboard. The boat ride is scenic and often includes panoramic views of the Cyclades. The journey itself becomes part of the experience, as you sail over aquamarine waters with the wind in your hair and the scent of salt in the air. Depending on your style and budget, you can choose from sleek yachts to traditional wooden kaiki boats, each adding a different flavor to the trip.

When to Visit
Rhenia is best visited between May and October, when the weather is warm and the sea is calm. July and August bring more visitors to Mykonos, so consider the shoulder months—May, June, September—for a more peaceful experience. Morning tours often offer calmer seas and a more serene vibe. These months also provide milder temperatures and longer daylight hours, perfect for a full day of discovery. Off-season visits are not recommended, as tours cease and winds can be harsh, making the journey less enjoyable.
A Contrast to Mykonos’ Buzz

Rhenia is a place to disconnect from the world and reconnect with the elemental forces of nature, offering restoration in its purest form.

With its secluded beaches, ancient secrets, and dreamlike waters, Rhenia invites you to slow down, breathe deeply, and connect with the soul of the Aegean.
