Chalkida or Chalkis, the capital city of Evia (Greece's second-largest island), is located at the point where Evia nearly touches the mainland, connected by two bridges. This fascinating city is world-famous for its unusual tidal currents. The "crazy waters" phenomenon occurs due to the moon's gravity and the Euripus Strait's unique geography, causing the currents to flow north-to-south and then south-to-north every six hours, creating a mesmerizing natural spectacle.

Witness these unique tidal currents from the Old Bridge spanning the Euripus Strait. Explore the Castle of Kanithos (also known as Karababa), perched atop the green hill of Fourka. Built in 1684, it once guarded Chalkida against invaders and offers panoramic views of the gulf and mainland. Admire the historic Red House, a landmark in the city, and learn about its architectural significance and rich past. Pay your respects at the beautiful Agia Paraskevi Church, an important religious site in Chalkida. For those seeking further exploration, venture into Evia to discover the Fylla Medieval Castle and its scenic views.

While Chalkida offers a more relaxed pace than bustling cities, you'll find a local shopping experience with boutiques and galleries offering unique finds inspired by the Cyclades islands. For a pleasant evening, enjoy cozy cafes, music bars along the shore, and a lively seaside atmosphere.
