A list of ten of the most enchanting hidden gardens tucked away in major European cities—including one in Greece—was recently compiled by The Guardian. These serene green spaces often escape the notice of even longtime residents.
Among them is the lush, little-known botanical treasure just outside Athens: the Diomedes Botanical Garden.
An overlooked oasis near Athens
While the National Garden in central Athens is a popular tourist destination, the Greek capital has another, far less familiar green retreat—the Diomedes Botanical Garden in Haidari. This hidden gem lies just about twenty minutes from downtown Athens by bus and stands as one of the most tranquil gardens not just in Greece but in all of Europe.
As noted by The Guardian, the vast garden spans approximately 460 acres. While the majority of the land remains in its natural state, approximately 11 percent is carefully cultivated and features over 2,500 different plant species.
An international showcase of nature
The garden is divided into themed sections, offering visitors a rich and varied botanical experience. Highlights include the arboretum, featuring tree and shrub species from around the world, as well as a vibrant ornamental plant section with 15 floral beds and 25 tranquil ponds.
Other dedicated areas showcase plants of historical significance—many referenced in ancient Greek texts—as well as collections of medicinal and aromatic herbs, economically valuable crops, greenhouse species, and rare native plants. A cozy on-site cafe enhances the tranquil atmosphere, making it an ideal escape for nature lovers visiting Athens or exploring the diverse gardens of Europe.
