Just a short ferry ride from Athens lies Kea, an island worth exploring.

Marco Arguello

One of the best things about living in Athens is the proximity to so manyGreek islands.

The island of Kea is only an hours ferry ride away from the mainland.

The boat departs from a scruffy port called Lavrion, about an hour from downtown in a taxi.

Even though Kea is the Cycladic island closest toAthens, few foreigners have heard of it.

The locals have never been interested in tourism.

The island has always been very self-sufficientthey have livestock, farming, and fishing.

Thats one of the reasons my father loved it so much, said Viktoria Fassianos.

Her father was Alekos Fassianos, the most beloved Greek painter of the 20th century.

Our summers were all about the simple life.

We spent hours together in the atelier, making flying toys and shadow puppets.

Alekos would put on puppet shows for the local kids.

For Alekos, it was the modest life of smallness that captured his imagination.

Love for the sea also drew Yannis Tzavelakos to Kea some 35 years ago.

The wreck, a sister vessel to theTitanic,was located by Jacques Cousteau in 1975.

Back then, it was only accessible by boat or on foot.

Kea is so authentic: an island of exclusivity, simplicity, art, and nature.

Some 300 staff maintain the immaculate grounds and extensive facilities with polished deference.

The ambitious scale can almost compete with the wide-open horizon framed in every floor-to-ceiling window.

Kea is so authentic.

It should be positioned likeSt.

Barts: an island of exclusivity, simplicity, art, and nature, Colson said.

In antiquity, Kea consisted of four distinct city-states, each with its own government and currency.

The islands settlements still feel like self-contained universes.

I went looking for adventure at Kaliskia, one of the far-flung beaches on the islands southeastern coast.

I shared the beach with a handful of locals who were having a picnic beside their pickup truck.

The archaeological site is all the more incredible because it is so inaccessible.

Most visitors make the pilgrimage on foot, following one of four relatively challenging trails.

At first, they would stay in the spartan monks cells at Kastriani Monastery.

Natural rock formations are strewn with pillows for daydreaming, or made into outdoor showers.

The stone walls of thekathikiesare so thick that there is barely any phone signal, and Wi-Fi is patchy.

At Kea Retreat, there are yoga mats and books on meditation, but no hair dryers or TVs.

Wedont like technology, said Uri Eshet, who is the resident chef, with a grin.

Vine leaves were stuffed with grouper cheeks, roasted apricots, and caper leaves.

Sea bass carpaccio was garnished with delicate pink garlic blossoms.

Dessert was a thyme-honey cream served in a handmade beeswax bowl.

But thats the beauty of Kea, the place with two names and a split personality.
