Create your own retreat experience in one of Greece's rarest natural sanctuaries

Private Retreats at ONAR

ONAR is not a conventional retreat venue. It is a secluded sanctuary where nature, comfort and privacy come together to create the ideal setting for groups that want to slow down, reconnect and experience something meaningful.

Located in the protected valley of Ahla, the property is surrounded by untouched Cycladic nature, dramatic cliffs, ancient trees, freshwater streams and direct access to Ahla Beach. Every part of the setting invites guests to be present, whether through quiet reflection, shared meals, creative work, movement, exploration or simply time spent outdoors.

From wellbeing retreats and creative residencies to leadership gatherings, culinary escapes and private group experiences, ONAR can be shaped around the purpose, rhythm and needs of each group.

Nature is the retreat

At ONAR, nature is not the background. It is the essence of the experience.

The protected wetlands of Ahla create a landscape that feels rare, alive and deeply restorative. The sound of the river, the shade of the plane trees, the open sky, the sea breeze and the silence of the valley naturally shape the pace of each day.

Here, guests are invited to disconnect from everyday noise and reconnect with the simple elements that matter most: water, land, food, rest, conversation, creativity and presence.

Food & Ritual

At ONAR, dining is not simply a service. It is part of the retreat journey.

Rooted in Mediterranean simplicity, seasonality and fresh local ingredients, each meal is designed to nourish the body, bring people together and support the natural rhythm of the group.

Menus can be adapted to each retreat, with options such as:

• Vegetarian
• Vegan
• Gluten-free
• Traditional Greek cuisine
• Fish and meat options
• Organic farm products
• Custom menus upon request

A shared table becomes a daily ritual - a moment to slow down, connect and experience the flavors of Andros.

Retreat Spaces

ONAR offers a variety of natural and sheltered spaces for workshops, movement, reflection and group connection.

Available spaces include:

• 100 m² Hexadome tent under the plane trees
• 90 m² covered pergola space
• Shaded outdoor areas
• Riverside spaces by Achla River
• Poolside areas with valley and beach views
• Ahla Beach for quiet moments by the sea

Each retreat can move naturally through the day, from guided sessions and creative workshops to shared rituals, outdoor experiences and free time in nature.
