Environmental ProjectWe believe that we do not have to damage the earth to accomplish our dreams
In 2003 we decided that we wanted to embrace and promote sustainable tourism in Greece, so we dedicated our mental, emotional and financial resources to protect the cultural and natural heritage of los Island

In the last decade, almost every successful island in Greece has become a victim of its own success.

Fortunately, Ios was saved by the hippies, thirty years after they were gone, making it today, not only one of the most untouched islands in Europe, but also, true to its hippie heritage, a top-rated place in the world to have fun. We intend to keep it that way by building only 1% of the land we own to ensure that our conservation efforts can be financially sustainable for generations to come.


Our conservation project has planted 68,842 trees and bushes around the island so far to restore the habitat that had previously been burned repeatedly by wild fires and land deforestation. In addition, some 550 ancient olive trees (most of them more than 300-years-old) which were about to be cut and sold for firewood in Athens, were transported from the mainland, by boat, to Ios.


We cut their brunches off to help them survive


Brought them by boat and trucks to Ios Island under the supervision of experts


Tend to them every day as they flourish again in their new home



Between 2003 and 2007 we purchased a significant amount of land on Ios with the purpose of preserving it for future generations. By pursuing a model of sustainable development that included safeguarding vast tracts of natural landscape and building a small collectionof villas, lounges and boutique hotels based upon environmentally-friendly design and construction, working closely with the local community thus providing direct economic benefits through responsible tourism development.

We believe that we do not have to damage the earth to accomplish our dreams so our aim is to use a very low-impact, environmentally sensible approach to sustainably develop the land by leaving 99% of it unbuilt, so that Ios’ natural beauty, unspoiled beaches, sense of place and Greek island cultural heritage continues to thrive for future generations of locals and visitors alike. We have made a conscious decision to build on only 1% of the land we own on Ios, leaving 99% to remain as part of nature to help ensure that future generations will also be able to enjoy the wild beauty of Ios and its magnificent beaches.


Cut and carved by local craftsmen

All the materials we use during the construction process, except for wood, iron, glass and cement are produced locally. The uniqueness of this project is that our venues are built out of materials that are extracted from the ground of the actual building site

Environmental Project


All the water from the daily cleaning of the venues and various water features is recycled in separate waste management reservoirs to be used for the watering of our trees.
Environmental Project


There is no exposed infrastructure anywhere on our properties; no electric or telephone lines are exposed as all cables are dag underground at a great cost in order to not pollute visually the environment.

Storm water management and harvesting is in the forefront of our land development philosophy. Every venue of ours has very large (for a total of 8.500 cubic meters underground water reservoirs to collect water during ...


Not only is the epic poet Homer said to have seen his last sunset on the island (his grave is supposedly at Plakoto) but it is also home to Skarkos. The oldest known prehistoric settlement dating from the Bronze Age, (3,500 BC) whose recent discovery changed the history of the Cyclades.

Reached by ferry or boat in 1:45 hours from Mykonos and 45 minutes from Santorini, this 70 sq mile island boasts some 365 chapels and 32 stunning golden sandy beaches thought to be some of the best beaches in the Mediterranean. Our project offers the only place in the Cyclades where you can spend a whole day in complete privacy in one of our beaches, enjoy the hospitality of five star resorts,explore Skarkos without the tourist mayhem, walk through the magnificent interior of the island which also offers spectacular sea vistas,and later at night embrace the islands infectious, youthful energy and party till dawn.

Believing that in the battle between man and nature the only victor is his delusion that his creations are more beautiful than nature’s. Witnessing that whatever a man destroys can never be restored to the quality that nature originality created it, no matter how good and honest are his intentions, we refused to develop our land for a decade as we worked out how to best ensure that our creations have no long-term negative effects on nature.

Our Philosophy

A message from the Michalopoulos family, creators of CALILO:
Life is more beautiful than we think, if we can only find a way to disarm our ugliness that won’t let us enjoy it. Every moment we live, we are faced with a choice to either create beauty in the form of happiness, kindness, generosity and compassion, or ugliness in the form of sadness, malice, stinginess and frigidity. Every moment we live is a blank canvas which we can either smudge until it becomes black and ugly or paint with joyous colours until it becomes beautiful.
During the process of conceptualising and creating Calilo both as a physical place and an emotional one, the exceptional beauty and emotional intensity of the land pushed us to realise how much we must strive to make life beautiful for others and to dedicate ourselves into creating and sharing the vast array of beautiful emotions it keeps generating with everyone who chooses to visit it. That is why at the heart of Calilo, our family’s project, one will find this pursuit and embrace of beauty acting as both its roots and its wings.
Our mission and deep desire as a hotel and hospitality brand is to offer our guests the conditions to open up their souls to their feelings so they can discover the beauty hidden behind even the most ordinary moments, discover the surprising warmth that the smile of a person they’ve just met has, the joy and fun-loving energy hidden in the rays of the Greek sun, explore the rare sense of freedom that carefree footsteps like to leave on a gleaming sandy beach and allow themselves to be mesmerised by the rhythmic musical notes produced by the playful waves of the Aegean Sea.
Lastly, our uncompromising yearning and enthusiastic ambition is to provide our guests with a physical and emotional environment that encourages them to set aside any form of ugliness and embrace beauty enough to Create A LIfe they can fall in LOve with.
